I have a 468 motor and last night at the track I noticed a light film of oil on the inside of one of my zoomie hearder. Can someone tell me what this might could be? :(
Thanks
Ray

If you have a header evacuation system it could be sucking oil out of the valve covers especially if you dont have baffles under your breathers.

Zoomies don't use header evacs!!!

Might be sucking oil through the guides if you don't run valve seals. Might be sucking oil through the rings if you run low tension rings. Have you done a compression check on that cylinder yet?

Could be Blow by from a ring not seated.
