Im looking to buy a s4 turbo. But the car smokes so im a little hesitant. It turns on fine. no problems. I let it run for 10 min and it turned on again fine. At idle there is little smoke. But when i hold the throttle at 4k rpms it smokes. I held it there for about 10 seconds and it started smoking. I let off the throttle and it doesnt smoke as much when it returns to idle. What can it be? i cant drive the car to see if it smokes under boost because the clutch is slipping. I did this 2 times and it smoked. the third time some smoke came out of the front of the car. Hood area..

I am searching here but i would apreciate it alot if someone can help out to decide faster

thanks for looking

 

do a compression test.. turbo could be smoking because of a bent fin from a blown apex seal .. or possibly it is overheating due to oil/ water starvation.. good luck.. start with a compression test

 

if it was a bad apex seal it would idle bad and sound erratic when going up and down the rpms. right..

 

you can have fun sitting online and guessing... but if i was you i would just whip out a compression tester so i could eliminate a bad motor as a possibility and go from there
