Thanks. That's pretty much what I have found in the good vs bad reviews I've read about them. It sounds like they have a low tolerance for neglect!

Anybody have any first hand experience with the rocker arm fixer things you can buy now? I have seen an ad on Craigslist for them, so that makes me wonder if all they fix is the thickness of your wallet! Supposedly, they keep the engines from spitting out a rocker arm?
