I went to overtake in my 2.5 DSE the other day, foot to the floor and it just would'nt go. I know a 2.5 p38 isnt the fastest thing but since that overtake it has no go whatsoever and the check engine light is on.

the PCV valve (i belive thats what it's called)has become completely disconnected from both the air intake and the other side. and now when it runs every minute or so you can hear a sort of backfire coming through the air intake and a mini explosion in the airbox.

the intercooler pipes were also fairly gunged up with oil and on start up it was spitting out specs of oil from the exhausts.

any sugggestions guys would be really helpful?
