can anyone help,recently bought imported wrx mreg and seem to be getting alot of smoke from the exhaust. also car is quite juddery now and again when first started any clues on what this problem could be would be appreciated.

 

Worn turbo, piston rings if on acceleration or valves if on lifting off the throttle I assume it's blue (oil) smoke? Not good really :-(

 

ive filled up with v power since i bought the car but this weekend used the cheap stuff,the car has only started to smoke since then could this be the problem,the car only judders now and again when the engine is cold

 

imported cars cannot run on 95RON theyre mapped in japan for 100RON fuel (huge differance) and when imported they have to be mapped to use 97RON at least to be SVA tests i think

 

well i wont be doin that again ill get some vpower in it tomorrow and hopefully that will correct the problem i just hope it aint caused any serious damage thanks for your response guys.
