rian Posted August 4, 2012 Author Report Share Posted August 4, 2012 (edited) Yeah bigport and smallport should both use the same 1-wire 02 sensor, same part number according to Bosch. I haven't got the engine light hooked up but I'll do that tomorrow. That's probably the easiest way to find out what's going on. I've had a few more goes at getting the engine running properly but no luck, I've discovered that the engine is not hunting when the TPS is disconnected, but it's still idling very very high. Sounds like 3000+ rpm (i'll hook up the tacho tomorrow). The engine smells pretty bad of fuel as well. I'm going to check for air leaks around the manifold and throttle body tomorrow.

It's_AUDM_Yo Posted August 4, 2012 Report Share Posted August 4, 2012 Could be the super rare 4AGE 3 rotor.... Yeah check for leaks as my friends s13 had one and it was causing it to idle incredibly rough and thats the end of my knowledge on this subject. I gotta get mine going!

kickn5k Posted August 5, 2012 Report Share Posted August 5, 2012 Webers4x48 had very similar issues with his ae82 a few years ago. Had an air lock in the cooling system. I'd try filling and bleeding the cooling system that should help. Quote Link to comment Share on other sites More sharing options...
rian Posted August 5, 2012 Author Report Share Posted August 5, 2012 (edited) ^Thanks for the input Stuart, I have a feeling it's a few issues that are causing the high idle problem. Today I discovered that the intake gasket was missing a big chunk (yes I had bought all new gaskets for this engine but wasn't planning on replacing them until I knew the engine was running and I wouldn't be constantly pulling off the manifolds etc) and was causing an air leak. I also discovered the timing was out, and I figured out how the idle up/cold start valve works and how to remove it. So I think all these things were contributing to the high idle, plus not having any coolant for the coolant sensor to read the temperature of. So most of these issues have been sorted: the cooling system is mostly plumbed up, the gaskets are being replaced and I'm going to borrow a timing light next time I come down so I can set the timing. The other thing I did today was install a water temp sensor, I'm really happy with it. Here's how I did it (excuse the shitty camera phone pictures, my camera is in Brisbane): Removed this bung from the AE82 4AGE external thermostat housing (AE82 4AC external thermostat housings have a TVS sensor here which you can also remove if you're using it in a 4AGE swap): Replace it with a 16x1.5 to 1/8 npt -27 thread adapter, I cut the adapter down a bit because it was too long: Then use some thread sealant and put the water temp sensor into the thread adapter, then use more thread sealant and put the thread adapter into the external thermostat housing: So I'm going back to Brisbane in about an hour, next time I come down here I should have this engine running smoothly.

rian Posted August 8, 2012 Author Report Share Posted August 8, 2012 Got an AE71 tailshaft! If this doesn't work with my setup I'm going to be very annoyed. Next update it should be a drivable 4AGE KE70! Quote Link to comment Share on other sites More sharing options...
It's_AUDM_Yo Posted August 8, 2012 Report Share Posted August 8, 2012 Not having much luck are you. Quote Link to comment Share on other sites More sharing options...
rian Posted August 8, 2012 Author Report Share Posted August 8, 2012 Not at all. I now have 4 tailshafts lol, the T series I bought ages ago, the auto KE70 tailshaft that was originally in the car, the manual KE70 tailshaft you gave me and now this new AE71 tailshaft. But this one looks right, 22 spline yoke at one end, what looks to be a Borgy flange at the other, I didn't measure the length or anything but I'm pretty sure it is an AE71 tailshaft. Pretty keen to actually be able to drive my car! Quote Link to comment Share on other sites More sharing options...
Willis Posted August 8, 2012 Report Share Posted August 8, 2012 I could possibly make use of that T series tailshaft if you don't need it?? Stoked to see it all happening buddy! Vids when it's done! Quote Link to comment Share on other sites More sharing options...
rian Posted August 19, 2012 Author Report Share Posted August 19, 2012 (edited) So the tailshaft I bought recently was definitely a T50 to Borgwarner tailshaft, so I went to fit it up to the car but it was about an inch too short... wtf?? I noticed later that it had actually been shortened for some ʞ©$ɟing retarded reason. But luckily I have a million other incorrect tailshafts lying around and was able to make one useable tailshaft out of a KE70 rear half and an AE71 front half, but now it won't be balanced... :bash:. I put the tailshaft in anyway because I'm sick of looking at them. And I also fitted up a T18 speedo drive, made a throttle body gasket, replaced the manifold and TVIS gaskets and finished off the water system, though I still haven't got the thermofan mounted to the radiator. The engine is running a lot smoother now, still idles a bit high but that is probably just the cold start system. So basically this car would drive if I put some fluid in the clutch system. Next time maybe... Edited August 19, 2012 by rian Quote Link to comment Share on other sites More sharing options...

rian Posted August 19, 2012 Author Report Share Posted August 19, 2012 (edited) Nope, my entire workbench is now full of useless tailshafts... At least I've learned something from it all. I shall get this new tailshaft balanced and I'll never have to think about it again. Hopefully. Edited August 19, 2012 by rian Quote Link to comment Share on other sites More sharing options...
