Robert, another thing I just considered… if it’s a 2000 to 2002 cylinder (I think?) hold off on removing the plugs. Those years have difficult plugs and can’t simply be re-installed. I believe those have to be glued in place. Anyway, tell us the year of the cylinder and any other details about the ‘blow-ups’ and maybe someone else can chime in with suggestions.
P.S. I could be wrong, but I don’t think the power valve is the reason for the blow-ups. I believe people used to just wire them open and run it that way (before plugs were readily available).
