ok, a week ago i had my 87 TII out. i was over at a friends house cleaning it up and putting new clamps on some of the vacuum lines. when i got ready to leave it would not crank. i came back a couple hours later and used the "pull the fuse" trick to get it to crank. it smoked very heavily and almost overheated on the way back to my house. i flushed out the radiator and used some block sealant bc i smelled coolant in the engine bay somewhere but could not trace the leak. after i let the block seal dry i refilled the coolant system and it started up fine, idled fine, and the temperature stayed normal. so me thinking everything was alright i went to bed. got up the next morning and it would not crank. so i pulled off the upper intake and cleaned the injectors with carb cleaner and it still wouldnt crank up. this morning i got up and pulled the spark plugs, cleaned them, turned the motor over a few times with the plugs out, put ATF in the bottom 2 plug holes, replaced the spark plugs and it cranked up after a few tries. the throttle feels very hesitant, it smoked a little bit, and it would not rev above 3800 rpms. it also wouldnt idle. so after it cut off on me a few times i kept the engine revved at about 2500 rpms for a couple minutes until i noticed some smoke coming from under the hood. i got out hoping to seek out the coolant leak and the car cut off on me... i tracked down the source of the smoke to the exhaust side turbo housing. i have no idea what to do now, any help will be appreciated.

also it backfires REALLY fuggin loud when the revs drop. thought the cops would be cruisin my neighborhood lookin for the crazy guy shooting his 45 in the air at 8am, haha

what colour was the smoke? im thinking cracked turbo which is leaking oil... But i dont know if that would cause it to not idle.

Rage01

smoke coming from the exhaust was white and for once did not smell like coolant, and the smoke from under the hood was just a greyish colored mist that smelled like oil.

Bio-Weapon

well if it smells like oil chances are you somehow managed to crack the turbo, causing it to leak oil. I believe thats a sign of a bad turbo.

by the way its a relatively new turbo...it was replaced with an aftermarket one (which one i couldnt tell ya) about 6 months before i got the car, 4 of which the car was parked.


EDIT: car has also not been driven hard and never saw any smoke coming from the turbo housing before...why would it crack all of a sudden just turning 2500 rpms for a few minutes?

Bio-Weapon

are you sure it was a whole new turbo and just not an upgraded compressor? the manifold still could be bad.

Rage01

ill check it out and see what i can see real quick and let you know what i find...any ideas about the idling/hesitant throttle?

Bio-Weapon

that just says vac leak to me. you might have put a clamp onto an old hose and it just cracked it a little bit.

ok, i looked at the turbo housing and the manifold and didnt notice anything out of the ordinary. tried starting it again too...started right up, cut right back off. still not idling...cranked it right back up and kept the rpms between 1500-2000 until i reached operating temperature. add coolant light came on a few times but went right back off each time. didnt notice any smoke from the tailpipes or the turbo this time, but after it cut off on me when i got off the gas i looked in the engine bay and noticed a very fine mist emanating from underneath the turbo heat shield.

anyone?
