A hurt valve... - ZR-1 Net Registry Forums

Paul Workman · 08-26-2009

Dr. Pete and his assistant Egore (aka AL) pulled my heads apart and discovered one of the exhaust valves had (for lack of a better description) an evacuation of material about 1/2" long and crossing the big angle of the valve.

Cleaning the top of the piston showed no signs of ingesting anything that Pete and I could see. I didn't have my camera with me, but here is where it is.

Pete's going to take it to the machinist and see what he thinks. It is a total mystery, at this point. But!

More later.
