Re: Valve tappet clearancePosted by JerryCPP(WA) on October 22, 2009 at 14:55:28 from (71.115.236.186): In Reply to: Re: Valve tappet clearance posted by Billderr on October 22, 2009 at 14:21:09:
Yes Bill, replacing the valves is the solution. Talking a farmer into replacing all six exhaust valves when only one is broken takes some salesmanship, for sure. When you see the price of those valves you'll see why. The exhaust are stellite faced, and on the big engines the exhaust are $odium filled - mucho dollars! When the valve head comes off it may only mess up the valve seat - that's good and easily fixed. When it knocks a hole in the piston, that's bad, but still repairable. When it takes out the cylinder wall, that's VERY bad, and requires sleeving the engine. Your mouse/corn story is a first for me, thanks for sharing it.
