Famous last words indeed! The only thing that concerns me is that I think I read on a thread somewhere about a guy whose cap got sucked up by the oil pump and shot out the side of the pump housing. Yikes. That would be bad.
As for your previous concern about metal on metal and the tappets running dry, you're right. My mechanic was actually expecting to replace either some worn cams or at least some lifters, but he said there was no damage at all. Got lucky there.
As for SEVEN tubes blowing out, I talked to my tech again today and he said that the previous owner probably just let the first one go or didn't hear it and then the other ones went one at a time--probably over the course of a year or two.
Can't wait to take it for a drive on Saturday.
