CAR - KE70
MOTOR - 4AGE, big port head with a small port bottom end.
USE - soon to be fun daily


hey guys am slowly getting through my 4age conversion but there a few things i need your help with.

Firstly what is the pipe in the picture and where is it supposed to go to, should i leave it like that? also what type of sensor is that, the one with the red rubber thing on it?



secondly, where do these two pipes go?


and one of them seems to have been put in by the previous owner, and not cleaned up very well.




this leads me to my next question, i found tiny little shards of metal in my sump, first thing i thought of was my bearings had gone, but could these be the shavings from the the holes that had been drilled? and is there an easy way of checking my bearings while the sump is off?

thirdly, what connects up to that plug and what does it measure? see the little black thing with three tubes coming out of it, where do those tubes go? and what do they do? another thing, what is supposed to go into that hole in the inlet manifold? i'm pretty sure it is a inlet temp sensor but i could be wrong.



also, all these vacuum pipes what do they do and where to they go?



one of them seems to be un plugged, should i block it off?





another thing, what do these plugs connect up to?







6: what is this pipe and where is it supposed to go?



7: whilst cleaning my harmonic balancer i noticed that a small amount of it had broken off, does this matter?



8: what connects up to all these points on the alternator?



9: when i was trying to tighten up one of the engine mounts i got a bit too into it and this happened



do you guys know how i would get this nut out of this socket piece?

10: and lastly, when i was mounting my gearbox onto my engine, all this oil came out of the end of it, where the prop shaft goes. do you guys know what type of oil this is and how to i put more in?





sorry for the mad long post.

cheers guys.

I can't help you with all of them, but the green/red plugs and that black plug I can... The green plug I'm not 100% sure on I'd have to go over my diagrams but the red one is for your cold start injector and the black plug is for your cold start injector...

I'll read through the rest in a bit

il take a stab at a few things for you.

the hose in the first picture looks like the hose which connects to the head like this. not sure what the other thing is


the sump looks like oil drain from a turbo.

i cant really help you with the vacuum lines as i havnt done that on mine yet.

the orange and green plug is for water temp at the back of the head i believe. it can be seen on the far left of the picture i gave you above.

that line off the plenum may go to the brake booster fro vacuum?

not sure on harmonic balancer. it looks like an indicator mark tho?

the plug on alternator will be on your loom. you have the big plug which is specific to only bigport 4age's if i recall correctly

throw away that socket and buy a new nut

if you tip the gearbox oil will spill out where the yoke goes. just drain it and refill with 1.7L of oil



hope this helps. im sure one of the tech wizards will answer more questions in greater detail soon, but thankyou for actually going to the effort of putting up detailed pics

Being an admin and this being my hangout part of the forum I eddited your thread to have appropriate numbers

1: external oil drain from the head, only smallports have it, because you have a hybrid engine the big port head it can either be blocked or you can mod your head for a drain. What is your engine going to be used for? any high cornering?

2: ones for the return line for an oil cooler, the other could of been used as an oil drain from the turbo. Stuffed engines don't make swarf, is the crap in the sump curled in any way?

3: dunno about vacuum lines but that hole doesn't look genuine, the sensor next to the hole is original air temp gauge. Was this engine on an aftermarket ecu before this?

4: two of those are for water, one of them is for the map, another for an idle control or something. Look up a vacuum diagram

5: Green plug is for the ECU, red is the wrong one, pull it out and put the one out of your original 4ac top water pipe and put it in instead.

7: no that's fine

8: been covered before on here, search for alternator connection

9: wind it back into something solid and then wobble it back and forward

10: its a good idea to drain your oil out anyway. Any auto store will have a listing for oil, just look up ae71 corolla. Its a 80W-90 or something

To add to SAMQ's post

1) Also pictured is the knock sensor (the thing with the red o-ring)

2) Ditto SAMQ, turbo oil drain and factory oil cooler return.

3) Yeah, most people do dodgy oil drains lol

4) Air temp sensor. The 'three pronged vacuum' thing: one goes to your MAP sensor, one goes to your fuel regulator, the other one is blocked off.

The rest has been answered or i don't know the answer

ok cheers, thanks for the help

cheers man, yea i'm thinking the same, don't think it would be a cooler line because doesn't the banjo fitting under your oil filter connects to the cooler and the oil drains back into the second one in the photo.cant think of what else it would be.

do you think i could go with out the tube that goes to the brake booster?

i had a look at it and it seems to be a little chunk missing, the indicator mark further round it.

ok sweet thanks

yea i think i might, will have a better go at getting it off tomorrow.

ok cheers dude.



yea the car will be used for drifting, but will it affect it that much if i don't have one?

yea i think it was running an after market ecu previously, don't know what, should i just plug up the hole?

sorry to be a noob but what is swarf? nah i don't think it was, i couldn't really see if it was, the bits were really small, like smaller then grains of sand.

ok will do.

ah k cheers, well thing is i didn't have a 4ac originally :/ do you think i could run the one thats already there or should i just get another one of a 4ac?

you wouldn't happen to know what number 6 is would you?

ok so it doesn't need to be gearbox oil, it can just be regular engine oil?
thanks heaps for your help much appreciated.




ok sweet thanks dude

Number 6 (assuming your talking about the vertical larger rubber pipe is the vacuum hose which goes to your booster. It will need a one way valve in it. I'd say you 100% definitely need the hose to go from your manifold to your brake booster or you will have no vacuum assist for your brakes. They will be HARD to use!!!

You only need to plug in the round plug hole thingy and the nut on the top of the alternator, you don't need to do anything with the three bolts on the back if thats what you were worried about.

With the stuck nut I would just chuck the whole thing socket and all. Probably pick up a replacement stud and nut first though. If this is happening with your sockets and you aren't doing anything stupid like 3 meter long pry bar or wrong size socket then you need better sockets.

Also I'm not trying to be a bitch or anything but do you have anyone helping you with this stuff? Cos to be brutally honest if you don't know some of this stuff I see a very difficult engine swap in your future. I would suggest getting an ae86 owners manual and a 4age engine manual, plus find a stock ae92 with a 4age and climb in the engine bay and take a shit load of photos!!! Then compare them to your motor and wok out what everything is!
The ae86 owners manual and the ae86 manual and even wiring diagrams ARE available on this site or club4ag or rollaclub because I found them and used them for my conversion!!

[marvis]

Stick a screw driver in the back of the socket and smash it.

I would suggest replacing the rear main seal and the seal on the back of the gear box while it's out also.

[timbo]

You won't need the knock sensor if you're running a bigport loom, so just take it out. It will also foul with RWD water lines and so will the oil drain in the block, this is unless you route it over with extra tubing if you are going to run one.

If you tip the gearbox up on its end it will leak. Drain and flush it before you put it in. Also marv's suggestion of replacing the seals/gasket isn't a bad idea while its out. When its in the car you can fill it through the shifter hole (1.7L) or on the passanger side on the box is the fill plug above the drian plug, but to use this you will need a little hand pump.

The vac lines on the throttle body are for a/c or power steering, I can't remember which one. I have niether in my car so the are all blocked off. The two line facing down are for the coolant lines to and from the idle control which is the thing on the bottom of the throttle. They are usually stuffed so you can blockthem up like the vac lines or plate the whole thing up and idle you car with throttle control when cold.

[grey_nomad]

Idle up for air con. Plug them if you don't have A/C.
