The car is smoking now. I don't know where the hell its coming from! it's definatly coming out of the exhaust. Color is white, possibly slightly bluish. Smells oily. how can I tell if it's the turbo or the engine oil seals? I've had the I/C out, didn't notice any excessive oil.

how much shaft play is unacceptable? I'm HOPING that it's the turbo, because I have a spare. I don't have a spare motor

 

it seems to be MUCH worse after hard accelleration AND high (3000+) rpm coast.
it almost seems to be nonexistant if I'm just super gentile and don't downshift/decel in gear.

 

how many miles? type of FC? when did this start?

 

'88 10ae.

40k on car, 10k on motor.

for all I know it's been doing it since I got it, I just now fixed all of the oil leaks

 

hm, i have no clue. if you knwo for sure the motor has that many miles on it, then i donno why it would need a rebuild already. Thats weird that there is already a new motor in a 40k car..

 

it sat.
for a very, very long time.
it also had syntetic oil in it.
it also never saw above 2500rpm.

 

BUMP.

 

never saw over 2500rpm......wow. i say the synthetic oil is to thin for the old dried out seals. try a thicker oil or something. I dont now how you would check the turbo though.

 

change the oil and go to somthing non sinthetic that is probably the problem. as you probbably know its suposed to smoke from the oil burning at high rpm's but just in pufs. if yours is constant then. i dont know man. but i have seen that the senthetit takes longer to burn off than normal oil. so swich and see what happens. thats my advise. good luck dude!

 

bump!

THIS engine has never seen synthetic, ever.

I'm using 20w50 regular dino oil

HOW CAN I TELL WHERE ITS COMING FROM??

 

Check the plugs, pull the turbo, check the downpipe, etc.

 

Original Turbo ? Or turbo 10k too?

 

turbo is used and questionable.


I noticed when coasting downhill at about 2800 in 2nd a constant cloud of smoke behind me.

I did a "test" that someone on the forum suggested where I held the car at ~4000 rpm with no load for about 60 seconds... didn't get any smoke. none at all, not even a tiny little bit.
