Q: Oil Spraying Out of Dipstick
I just recently purchased a 1967 bird with a 400 and an automatic tranny. It needs some work but for the most part is all original. The motor has 670 heads and is a YT.
The engine seems to have a lot of power but when I rev it very high I get oil thrown out of the dipstick tube onto my exhaust manifolds. I suspect the bottom end of the tube is missing or the windage? tray is not installed. I am the third owner of the car. The second owner told me that the engine had been rebuilt. Bored .40 and bigger cam installed, heads have been redone.
A: Oil spray out of the dipstick tube could mean excessive blow-by (i.e., the rings are gone or broken ring). Run a compression check before you break the motor down.
A: I had the same problem when I installed after market valve covers. I was waiting delivery on a oil breather, and since I had just installed headers and a RPM performer manifold I didnt want to wait for it, so I just blocked the cover off and took it out for a run. Guess what, oil shot out the dipstick due to back pressure. Suggestion to original question. Make sure there is a clean unblocked breather on one of the valve covers.
