old gas cant bend a valve or a pushrod any more than new gas can make them straight again....

rotten gas that turns to varnish...will gum up the valve and the valve will not be able to open...bending the pushrods...

and went the valve hangs open...guess what..the piston hits it....as I said before...been there with an old motor home that was parked for years...
