Hi i have a 1997 wrx turbo,and it has just started leaking oil from the front of the engine between the cam cover and engine,i have phone up a subaru repair's and they have said it is my cam,or crack seal's,i now loose power on boost is this the reason why or could it allso be the blowing exhaust's cheer's andy???????

 

It's quite common for the cam covers to develop a leak now and again although this shouldn't effect the engines performance so I would look elsewhere for that problem. A badly blowing exhaust will effect the engine performance to a degree though.

 

Cheer's m8 for your reply,someone has told me it could be the boost control valve not sure????????????
