I have a 95wrx import and have noticed a few things go wrong at once. Firstly the car has been de-catted and has a HKS induction kit fitted (done before i purchased) Right so the problems are from time to time i seen to lose boost at around 4500 - 5000 revs and when i change gear it doesnt return, also i have noticed a small pool of oil under he induction kit after every outing (not excessive but definatly engine oil) Last but no means least when the cars started cold i get a puff of blue smoke which smeels like petrol but then nothing after that. I csan drive the car normal or hard and there is no misfire etc and no smoke after she has been started first thing.

Thanks in advance

 

Check oil level is right. Check all boost pipers and breathers are clean of oil, and try clean your boost solenoid. I'm not 100percent but worth a try for nowt.

 

Could possibly be the turbo on it's way out, but faults can be interpreted so differently by us from what people write. Your best bet would to be to take the car and get an opinion from a specialist

The oil defo does not sound good though and could be damaging your engine everytime you start and drive the car (oil on maf and not reading right, mixture not right as oil is being burned, leading to detonation etc.). one of mine did this as I didnt see to it early enough, now its had a new engine due to a broken piston

 

cheers guys im going to phone motoscope in the northeast today or tomorrow to book her in so they can put it onto rolling road and there machines to tell me whats wrong, prob worth spending £50 - £80 to have it all checked rather than a hugh bill for a new engine
