I think if a camlobe is bad enough to cause the problem, I will probably be able to see it without a scientific test.
I adjusted the valves for her not long after she got the car, but I wasn't paying any attention to camlobes particularly. The valve cover will probably have to come off anyway, I'll probably go take a look. If I don't find anything else, then I'll use a dial indicator.
Thanks for mentioning this. I need some things to make me think "outside the box".
Wish me luck,
