BBC timing cover seal
I have a buddy that has a BBC timing cover seal that that came out on a new chrome timing cover. He called me and I told him to try another timing cover that maybe the new chrome one was bad. He put a steel one on with a new seal. He started the car and said he stalled the converter with his transbrake and it started leaking extensively from the seal. I asked him if the vent tubes on the valve cover was blocked or plugged. He said he could blow threw them with no problem. From the valve cover to the header. Anybody know what could blow the timing cover seal to where it would leak if the vents in the valve covers arent plugged?
