As tempted as I am to question the dealer again, I am going to wait and see how this goes. The valve seals are on order and im waiting for the call. The dealer called the ford tech line who informed them that they are experiencing valve seal issues with this engine although I havent seen anyone else on here having this problem.So, are we to ass-u-me they ran a leak down test with the valves open?
I understand very well how the seats and seals function. When the valve is open oil can enter the chamber through guides if the seal is leaking. What I fail to comprehend is how pressure can reach the seal if the valve is closed, as required in a leak down test.
