are you sure they're screwed down all the way? don't strip 'em, but make sure they snug up on the valve stem.

they are screwed all the way down, could it have anything to do with the red adustment screws in the black covers, adjusts the spring pressure on the rave valve cap mine is a 951 supose to be turned all the way down but on the 800 only turned.down till there flush?

Nope... the red screw cap won't have anything to do with it. You might be getting to much exhuast fumes past the housing causing it to blow off. To fix that, you have to get a new housing. Also, check and see if there are any markings/gouges/scratches on the valves themselves.
