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?

I lapped in new valves with a drill. The drill had a rubber hose attached to a drill bit and the other end was attached to the valve stem. I would spin the valve and keep letting it up and down to lap it into the valve seat. I saw it on a you tube video. I had to lapp them pretty deep like .020" or so so they would be .008" EX and .006" IN. I am thinking I should go over them with the had lapping tool one more time.
once I get one out Ill take a picture and post it. -------------------- |
