This is a view of an outer drive

Sometimes, if the client keeps driving an engine with a burned valve, the heat buildup in the valve head can get so high that the whole head melts and breaks off. You are looking down the cylinder to the top of a piston that has met it's untimely demise. Yes, that's a big hole in the middle...Good night, Irene.

Again, valve clearance adjustments can help prevent this from happening and save big dollars! Ask us.
