THANKYOU in advance, one day I might be able to return the favour.

So I own a 78 ke30 corolla with 3k-c engine. My oil cap disappeared. it was round in shape and the push in type (rubber) According to every parts manual & toyota themselves, a 78 corolla is meant to have the screw in type with hand grips on it. Which was confirmed when I went to the wreckers and the ke30 had that exact screw in type.

-What is the go, and what can I use to replace it other than the sleeved replacement I made (auto stores don't have anything big enough)

 

The second part is when it disappeared it sprayed oil everywhere, therefore leaving my oil empty, and now my engine wont stay on unless I hold the key halfway between the starter motor and on- my thinking was this was some sort of safety thing so the engine won't blow? but It has the same problem since I filled the oil.

I find it hard to believe they aren't related since it only happened straight afterwards and I have never had electric issues, but hey stranger things have happened.

THANKYOU (I'll ask another mechanic but the apprentice gave me a blank look and I can't bring the car in)

Any K motor will have a cap that fits. Thinking about it most Toyota ones will fit.

 

You shouldn't lose all your oil out of the oil cap. Unless you were driving it for months. If so, silly.

 

Sounds like you are holding the ignition in the start position and the starter motor is turning it.

 

Probably totally f**ked your engine if you ran it w/o oil for ages.

 

Which is hard to do with a K motor.

ignition switch sounds kaput?

now my engine wont stay on unless I hold the key halfway between the starter motor and on-

 

This happened to me once on my old ke30 it was the ballast resistor

ballast resistor eh.. gold star :dance: I shal give that a go ( i like how google sais they weren't used after 1975).

thankyou

This happened to me once on my old ke30 it was the ballast resistor

 

Me too, the engine starts but then dies as soon as you let go of the key. Something to do with the power to the coil bypassing the ballast resistor when the starter motor is cranking over, but then when you let go of the key the circuit swaps back and the power then has to pass through the ballast resistor to get to the coil, or something like that. Check the connections to the ballast resistor, I'm pretty sure oil is an electrical insulator so if oil went everywhere in your engine bay it may be stuffing up the connections, but usually it's just because they're corroded or something.

Cheers guys, It was the ballast resistor and repco + $4 fixed everything. :y:

It's more of a curiosity now, but does anyone know the deal with the oil caps screw in compared to push in? what models etc

Me too, the engine starts but then dies as soon as you let go of the key.

Yep i drove 20 min holding the key in the gap between on and when the starter motor kicks in :laff:

Just remove a rocker cover from a later model ke30, possibly from 1978.

Or ke55 from 1979 as they may have the same number of outlets for breather hoses

like your original has, with the only difference being the cap screws in as the

rocker cover has a thread for it :y:

if you can't find a oil cap for it find something else the right diameter that fits. i found one of those rubbery bouncy balls as a oil cap in my old ke30 :blinks:

I've got a cap sleeved with a bike tube which is nice and snug and still looks the goods, and a spare 3k there as well, with the time I spent doing the rounds looking for a cap I could of changed rocker covers :laff:

like I said it's more of a curiosity now because all the parts manuals (4 seperate stores & wreckers) said a ke30, 3k is a screw in type. btw the only time repco has failed me :hmm:

The push in type is just the older version... My Ke10 and Ke20 had these originally.

The 5K I put in the Ke10 has the screw type :)

3k is push in type. 4k and later are screw in. Find ur self a 4k rocker cover
