laser rs turbo awd wierd problem

04-20-2010, 10:38 PM
hi i have a 92 laser rs turbo awd
the car starts and runs fine but it has no boost and a slight black discharge out of the exhaust
i checked compression and its holding at 114.5-115-115-115.5
i cant find any info on this subject
i though it was intercooler or the piping or maybee the waist gate
some one told me it was bent valves but before i go pulling the head off the engine i wanted to know what you guys thought

I'd guess the turbo is shot (black smoke is oil), but not sure if compression is right or not. Not used to Colorado altitudes, but if they're that close together, you might be fine in that respect.

Compression does seem really low, but it's even so that's good. How many miles are on the motor?

Slight black discharge such as exhaust or oil?
