I don't know what the compression ratio is. I don't know what shaved the deck means either. Sorry, I think for a female who is a nurse, not a mechanic I do know a little about engines but the terminology here is lost on me. Thanks for your suggestions though. What would I have to do if it is a valve train problem? Have the valves adjusted? Is that expensive? If it is just valve noise do you have any recommendations as to how I can get them to be quiet? Is there something I can add to the engine such as slick 50 to quiet them or would I be wasting money? Again, thanks, I sincerely appreciate your input ....any ideas are worth considering. VJW
