continued from old forum.... i am getting a lot of oil being blown up the breather into the air box on my '85 gti 8v. it then drips out the bottom into the inner wing and along the spoiler and then drips all over the place. previous suggestions were piston rings and/or valve seals but after a compression check all cylinders were at the recomended pressures, so this ruled out the above in my opinion. anyone got any other suggestions? The car has an after market cam cover on(red cast ally thing with "rapid" written on it) I am thinking of changing this to see if this releives the problem...........is there a difference between cam covers on k-jets and digifants? i notice the digi has a circular thing on top whats all this about? cheers for any help
Hi there, a compresion check wont show any wear in the valve guides or seals as the compresion reading is produced while the valves are shut. Its worth doing two compresion checks one "dry" and one "wet" wet is where you squirt a little oil into each cylinder which improves the sealing of the piston rings, if the wet reading is alot better than the dry reading especially if only one one cylinder this may point to ring or bore problems. Is the engine "breathing" alot when running ie if you take the dip skick out when running does it look like a steam train?
8vvw, took the dipstick out when the engine was warm today, there was some visible vapour, but nothing excessive, only at idle though... when revved the vapour dissapeared. wouldnt piston rings or bore problems show up in uneven running or loss of power? its running fine and still pulls hard! going to get a standard cam cover this weekend and see what that does for me
