My efing valves are leaking! I lapped them down to the right height as suggested by delta cams. Now after installing the valve springs I poured some paint thinner in the ports to do a leak test and the thinner is coming out through the valves and into the combustion chamber. Any thoughts?? What did I do wrong?

QUOTE (Smaay @ May 27, 2015 - 10:30 AM)  what did you set the valve clearance too? the valve clearance is 0.006" on the intake and 0.008" on the exhaust. QUOTE (Bitter @ May 27, 2015 - 11:58 AM) I'm assuming you have a nice even gray band all the way around and cleaned up all the compound before checking? Any compound left over will cause more leaking than normal. How much leaking are we talking about? Yes there was a grey band around the valves. I wiped up the compound with a clean rag when I was done lapping each valve. It is leaking slightly not pouring out but leaking. -------------------- |
