Chuck, Then engine wasn't making any rattling before I stopped driving it. I only stopped because I lost 4th gear (at least) while driving on the highway. So if the valve isn't bent, and the valve stem is in good shape I can replace the keepers in place. That would be a miracle. I'll see if I can gather the parts for an 'air hold'. I have a compression gauge perhaps the hose from that will work.
