As I was reading your thread, one thing became apparent; if someone has a comment or an actual experience that doesn't support your opinion, you go ballistic. I think CINDY2 was just saying that many years ago (perhaps 25) she owned a car that had the pollution control disconnected and this caused a head gasket to blow. It was nothing but stating something she personally experienced. Not a discredit to you or you idea. It was just a comment about messing with emissions.
The forum is meant to stimulate interaction among Crossfire owners and pass on information that is useful and informative. Jumping down another members throat because of a simple post may well be one reason female members rarely post. I am surprised she didn't respond to your attack, but she is probably too much a lady.
