Welcome Aboard ! My guess is that the compression ratio, will increase, as you compress the greater amount of induced air/fuel mixture, into a smaller volumetric area, as a result, of the flat replacement head, with smaller head chamber volume. You can readily find this new compression ratio out, if You refer to the 7K manual; or mathematically work it out by dividing the calculated swept volume, plus head volume; divided by the volume of the head, when the piston, is at it's highest point. Time to get your pipette out ! Cheers Banjo

I would suggest that you remove the rocker cover, & then start the engine, without the rocker cover, if nothing visually, immediately appears to be amiss. You will probably find a tappet adjustment, that has come loose, or maybe a cracked or broken valve spring. Let us know what you find. Just check that the sheet metal on the inside top of the rocker cover, has not come loose at one point, so that it vibrates at certain high revs. Cheers Banjo

Not quite sure, what you are trying to do. Is this for entry to the car (unlocking it) ? Did you lose the FOB, or the FOB is not working. Always best to buy alarm systems that include the FOB, & are paired. You say the one You purchased, works fine, but that You don't have a FOB for it. Is the original one, a Toyota OEM item ? I've used simple control boards, c/w a FOB, for bypassing faulty horn button rings, but never replaced a door lock one. Cheers Banjo,

We actually had someone from Cyprus on here recently, asking for assistance; & I meant to ask him or her, had they ever been to see the olde Toyotas, frozen in time. Although the strip of land, I believe is under UN control, & has UN police there permanently stationed there; I believe there are guided tours thereof. An Australian TV crew visited there several years ago, & I watched the show on TV, & couldn't believe what I was seeing. One owner Corolla ! 38 klms on odometer. Pickup FOC, at your own risk ! https://en.wikipedia.org/wiki/United_Nations_Buffer_Zone_in_Cyprus https://japanesenostalgiccar.com/more-nostalgic-toyotas-from-cyprus-un-buffer-zone/#:~:text=Beneath the Ledra Palace Hotel,smashed windshields%2C or missing parts.

Hi Sheryl, There are a lot of circuit & wiring; for the indicator lights, as they are also part of the hazard warning system, where all turn indicator lights are used. There are several things that could be preventing the indicators working. The wattage of the bulbs, is a function of the flashing rate. If the bulbs have been replaced with LED equivalents, they will not work. The flashing device, which is a smallish aluminium can, with three (3) spade terminals; is located usually, behind the panel to the RHS of the accelerator pedal, if a RH drive model car. The stalk assembly switches are known to wear out, if the assembly is olde. ebay your best bet there. There is also a hazard switch on the steering column, which has a number of wires, that also could be an issue. There is a big cable & socket at the base of the steering column, which passes all the indicator & hazard switch wiring to the chassis/body wiring harness. All the wiring for the turn-indicators, was pretty much the same in all Corollas. LEGEND: 121 = Flasher Unit, 157 = Hazzard Warning Switch, 177 = Turn Signal Switch Arm Items 24, 25, & 159, on the RHS of the above diagram, are the two horns & the horn switch, on the steering wheel. Here is a section of the wiring diagram for a KE-70. All the bulbs at the bottom of the diagram, go to ground/chassis. The KE-70 had two fuses, one for indicators & a larger one for hazard, as twice as many bulbs were illuminated, in "hazard mode". All these points can be visually inspected. If it is not a simple blown fuse, or something, that is visibly broken, missing, or incorrect; then you will need a 12 volt test light & a wiring diagram above, to sort this issue out. It could well be a need for an auto-electrician. Hope that assists. Cheers Banjo

We'll need a little bit more information than that statement, before anyone on this forum, will be able to assist you. 1. Does the engine crank, via the starter motor, when you turn the key ! A little bit more information, will allow us, to possibly assist You. Cheers Banjo

Have a quick look at this video, & see if the Starlet ECU, featured there, looks the same as the one you have. https://www.youtube.com/watch?v=_z5hnVmlyuI Cheers Banjo

Hi Brayden, Read your queries, with interest; & Altezzaclub's response, which as always; is very thorough. There was line in His advice that jumped out at me. Several years ago, I took my KE30, with a 4K-U engine, down the inland New England highway, from Brisbane - Sydney. Somewhere up near Guyra, the car started to develop, very similar issues, as You describe. I pulled up in a public car park, right across from a motoring store, so if I needed anything, I didn't carry in my boot, then I had access to it. I did all the usual things like clean the bowl & jets in the carby, & unhooked the fuel line at the carby, & turned the engine over, to ensure I had fuel delivery. All good ! I took it for a run, & for 20 minutes; & it was running pretty good. I was just about to "pat myself on the back", when it occurred again, well away from any town. I pulled up in a little park, near a bridge, & lifted the hood/bonnet again. Yes it was the fuel cut-off solenoid, which is energized, whilst ever, the ignition switch is on. I disconnected the wire from the carby assembly, that was just a push-on connection. I then hooked my trouble lamp up to this wire from the ignition, & an earth; then turned on the ignition. The trouble lamped lit, but when I started tracing the wire back from the carby, & started wriggling the wires, the test lamp flickered. Found the crook connection; corrected same, & I was on my way to Sydney, without any further issues. However, the symptoms whilst driving, were similar to what You described in your post. I hope it is the same fault in your car, because the intermittent wire connection, to the fuel solenoid, is a very easy, & clean fix. P.S. However, if You come back, & advise your engine does not have a fuel line cut-out, on your particular carby; then We are unfortunately; back to square one again ! Let's know how You go. Cheers Banjo

Hi Dananjaya, Yep, a bit more complicated than the olde days, when there was a simple cable between accelerator pedal, & the throttle body. This following link, has a good description, of how they work, & also describes the one like yours, with Hall Effect switches, which do away, with the need for resistance & wiper brushes. https://premierautotrade.com.au/news/accelerator-pedal-position-sensors.php Enjoy ! Cheers Banjo

Hi Diederik, Thanks for your enquiry post. I went looking through my collection of K Series manuals, which I have accumulated over the years, but unfortunately, I do not have the 7K EFI one. There is a "flip the page one", at the following link, which may be of use to you; although I'm guessing, You would like pdf version, so you could print out pages; only relating to a particular subject or topic. https://anyflip.com/ljmk/daij/basic I'll keep looking, & if I come across anything, I'll drop You a note, on this thread. I have a 7K EFI manifold setup here, that I've mated to a 5K engine. However, it is all going to be controlled by an aftermarket ECU, so I don't really need the manual or wiring diagram. Of interest, is the fact, that the idling air control valve did not work, & was beyond repair. I actually found a brand new one, still in a box, on a UK website, at a bargain price; as it was a Toyota original, & not an aftermarket replacement part. The 'Shopee" website in Malaysia, appear to have these for sale. https://shopee.com.my/verify/traffic/error?home_url=https%3A%2F%2Fshopee.com.my&is_logged_in=true&tracking_id=260df8ec5bb-5fbf-43ea-b683-dfc791055af6&type=1 Cheers Banjo

Hi Michalis, It's not too hard, as your olde 30A alternator (first picture) & the newer 40A alternator are both designed for an external voltage regulator. Both have the exact same connections, just in different places. So the top picture You depicted, is a 3 wire plug connection, with 3 wires, The second picture also has F, N, & Earth point, except it does accept the plug on your harness. You will have to cut the plug off the harness, & connect the three wires, to the corresponding three (3) points on your replacement alternator, marked F, N, & E. The last connection, is the +ve or "battery" wire, which will be the thickest of the cables, On your olde original alternator, there is a big "B" for battery, moulded into the alternator aluminium casing, right next to the terminal. On your replacement alternator, there is also a big "B"; moulded into the aluminium case. Hope that assists. Cheers Banjo

Hi Michalis, & welcome aboard Rollaclub ! There are a lot of things on a car, that if they break down; don't stop You from getting from point "A" to point "B". Windscreen wipers, headlights, a horn; or even an reverse gear; don't have You broken down on the side of the road, & isolated, & going nowhere. However, the engine is paramount; closely followed by the alternator. Even with a fully charged battery, if the alternator fails; it won't be that long, before the engine comes to a stop, on the side of the road. The "electrical loads" on a battery, have only increased, over the years, as we add more & more electrically powered devices & gadgets to our cars. There are ways, in which You can decrease the electrical load on your car, by say . . . . . "converting all light bulbs to LED ones". I did this in the past couple of years, & it was a really good upgrade. Brighter lights; less voltage drops; & lower power consumed. When our Corollas were first built, the alternators fitted were pretty standard, & produced 30-35A maximum, at their output terminals. Invariably, the early ones had an external "voltage regulator", that consisted of relays that vibrated to produce an excitation current to the alternator. Later ones, like the Bosch one, you imaged; had a solid state regulator, built into alternator body, & very easily replaced. Alternators have improved dramatically over the last decade or so, & alternators of similar size, to the ones You depict, can now produce outputs of 80-120 amperes. I purchased an alternator on line, that was cheaper than an new replacement, exactly the same as the original fitted to the car. It produces 120 amperes output max. 120 Ampere rated alternator fitted to my 5K engine It was the best upgrade I've done, of recent years. The single biggest wearing item, in the alternators, You've depicted is the commutator. These wear & get "out of round", & result in more rapid wear of the carbon brushes. I would strongly suggest opening the alternator up, & inspection, commutator & brushes, before fitting a second hand unit to your car. Another alternative, is to find a second hand alternator, with greater output, that will fit. Years ago, I purchased a reconditioned alternator, from a Toyota Hilux utility, that produced about 65 amperes max. Off memory, it only requires a couple of washers, on the mounting bracket bolt, so that the pulley at the front lined up perfectly. Hope that these suggestions assist. Good Luck ! Cheers Banjo

I'd suggest having a good read through the Rollaclub website, & you'll find a wealth of suggestions, & experiences of others, including myself, going back many years. I just popped in KE30 front brake upgrade, into the search box at the very top, of this page, & it found 37131 references, & 1486 pages, where this subject was covered or canvased. Good Reading ! Cheers Banjo

Joo, if you click on this link, there are a lot of threads, from other KE20 owners, with suggestions as to what is; & what isn't possible, with wheel size upgrades on the KE-20 Wide Wheels on KE20 Cheers Banjo

Hi Joo, Welcome aboard ! I wouldn't suggest going more than 14" wheels, but before doing that, there are a few things to consider. 1. Are the addition of larger wheels, purely for appearance aspects, or are you considering other upgrades to engine, gearbox, & diff, further down the track, as you advised the car is OEM. 2. If at sometime in the future you decide to upgrade the differential, you may find that these new wheels you are going to purchase are no longer useful. If you are purely wanting to fit it out, for appearance sake, then I would take it to your local tyre place, who invariably market/sell wheels also, & they will put it up on the hoist, & take some measurements, & advise, what is possible, & what is not, without "tubbing" the rear wheel arches, or other mechanical modifications. Lets know what you eventually decide. Cheers Banjo

Welcome aboard ! How long has this KE30 been sitting in this yard ? If it has been a long time, & the engines condition, is unknown; then there are several things You should do before trying to start it. The first thing before even trying to start it, is to remove all spark plugs, & pour a little light oil, into each spark plug hole. Let it settle for fifteen minutes, so the light oil, can seep down through the rings, & wet the lower bore. Make sure there is oil in the sump, but if it looks old & very thick, then change the oil, & oil filter. Then take a socket & bar, & place on the crankshaft pulley bolt head at the front of the engine, & see if the engine turns over easily, clockwise, with no spark plugs inserted; which means there will be no compression. If that all works so far, then hook up a battery, & turn the engine over with the starter motor. If the engine spins freely, then there are two other things You need, which is fuel & ignition. Undo the fuel line & turn the engine over with the starter motor, & ensure fuel is being sucked up from the fuel tank, at the rear. Likewise, Hook a spark plug up to the output of the ignition coil, & earth the spark plug body, & check there is a spark across the spark plug. If all good for fuel & spark, then replace all spark plugs & leads, & try to start it. However, before you try starting it, ensure the air filter is not blocked. If the air filter is in questionable shape, then remove it altogether, just for the first start. Let us know how You fare, or whether You get stuck, anywhere, along the way. Cheers Banjo

Hi James, I've had issues getting them off previously, but the technique Altezzaclub has suggested, & You have tried, always works for me. I would suggest removing the nut, & squirting some WD40 or similar, down the splines on the shaft. Leave overnight, or even give them a second squirt. It will come. They are reasonably fine splines, & slightly tapered, resulting in them jamming, when the nut is tightened up. A tapered spline, sometimes needs a sudden jolt to free it. If still no go, get a bit of square timber, & place it behind the plastic boss of the steering wheel, & a few taps with a mallet, from the underside/ backside, will get it off. Cheers Banjo

That looks so sad ! Your photo lacks a bit of high resolution; but when I zoom in, I can see why you might want to replace the upper & lower components completely. The upper one is a "no brainer", as I believe in all models, it was totally removable, & is just a bolt-on component. The lower one is totally the opposite; & is a completely welded in component. I agree with Altezzaclub, that blasting the lower section back to bare metal; or what's left of it; is your first option. Good luck ! Has this car lived in an area, where it snows & there is ice on the road in Winter, where they spread stuff/salt on the roads to stop icing ? Cheers Banjo

Hi Adam, All the Corolla's around that era, had very similar wiring diagrams. Some of them, are hell to read, as there are so many fine straight lines. http://www.retrojdm.com/ScanViewPage.asp?ScanID=40&Section=Supplement&DPI=100&Filename=S5-03 - Electrical Wiring Diagram for Models KE10(L), 15(L), 16V(L), Series.jpg This is how they should all be presented. The real problem, if you are tracing a circuit; as wire colours vary, depending where the car was assembled. The Australian assembled ones, put together by AMI in Melbourne were a typical example. If they ran out of a particular colour wire, they just added another colour. i rewired my engine bay loom, once, & found the colour changed on some wires from one end to the other, with a join, in a wrapped harness. I only found it, when I unwrapped the loom ! Good Luck ! Have you got a specific electrical issue, or are you "rewiring" ? Cheers Banjo

Hi Concerned Dad. You've got me scratching my head, & totally mystified. We are talking about engine oil here ? Is the oil coming out, when draining it; milky, or aeriated in any way ? Does it appear to be thin, like it has lost it's viscosity ? Does the "screw on oil filter" look like it has been changed recently ? Are there any noises coming from the engine, that could indicate the the oil pressure is low. This is an automatic, so a bit weird that something happening in the engine, all of sudden changes the auto changing, to "irregular & slow". I would not be driving it far, if at all, until You get to the bottom of this matter. I had something happen like this many years ago, in a Fiat 125. The oil pressure "over pressure valve", in the oil pump; jammed open & bypassed everything back into the sump. The reason it jammed was a piston skirt broke off, (common in early Fiats) & a little fragment of piston skirt got jammed in the oil bypass valve, when it opens a little sometimes, in the first minute or so, on a cold Winters morning, when the oil is initially very thick & viscous. I'll be interested to hear what You ultimately find the issue, to be. Good Luck ! Cheers Banjo

5 litres overfill, & being driven 14 miles home, has obviously caused issues. My personal belief, is that the 5 litres overfill, could have well resulted in the crankshaft connecting with the overfilled oil in the sump; which would have it saturating the cylinder walls, below the pistons. Some of this oil would have got past the rings, & foul the spark plugs, which You found to be true, & replaced the spark plugs. However, the greatest damage would be that a of of that excess oil could have splattered the crankcase breathing system, & got back up into the air filter. If the paper air-filter became clogged, it would seriously restrict the amount of air going into the engine. I'd be changing the air filter element, & maybe the distributor cap. If you have had tracking inside the cap previously, it can create tiny carbon tracks on the inside of the cap, & they will reoccur, unless the cap is replaced. Spark jumping across terminals on the inside of the dissy cap, can be caused by an open circuit spark plug cable or an extra wide spark plug gap; but is more than often caused by the carbon bush in the centre inside of the dissy, either falling out, or the spring behind it breaking. Once You do find the issue, & get it going properly, I'd be giving the car a good long hard run, on a country road, to bring it back to normal. Let us know how You go. Cheers Banjo

Hi Daniel, It's Saturday morning, & although I saw Your latest post yesterday; I just took the time to read right back through your build, from when You first posted, 15-16 months ago. It is a wonderful build, & a beautifully, finished project; with attention to detail, which adds to the quality of the result. You should be very proud of yourself, & trust You have many, many, happy trips & memories, with it, in the future. Cheers Banjo

Love your dedication, at something, that takes a lot of time & patience; both of which You've got. Hat's off to You ! Cheers Banjo

Keep the photos coming ! We love photos. A photo tells a thousand words ! Cheers Banjo

Welcome aboard Foxxtrott ! I'll bet you didn't figure on getting such a detailed response, as Altezzaclub's advice; in such a short time. I found his advice excellent, & a good read; & wish a lot of that aftermarket suspension accessories, were available years ago, when everyone on this site (including me), were trying to improve their suspension setups, with swaps from other Toyota vehicles. You can still do that, if the professional kits, are outside your budget, but many of the swap items, are pretty rare to find at a wreckers these days. Good luck ! Cheers Banjo
