hi all was out in my moddified 93 wrx last night when i seamed to be getting a lot of knock on the comannder and the engine seams to be breathing a lot and when you start it there seams to be a lack of compresion on one of the cylinders whats it most likely to be?


cheers david

 

Piston rings? Blowby due to one of the ring lands being damaged?

Have you done a compression check?
