a registered 112 didn't do it... (almost two years ago...) =D But would that 95 have caused it, and then the noise gone away after about 30 seconds(after i did the second 95 mph stint). And then i've been driving it around the rest of the weekend and no noises have been present until this morning...?

Anyway, I took out the spark plugs, and sure enough, the third one has been bent. The gap is very small and the tip is off center. I looked through the plug hole at the piston, and it is dented up a bit...

My friend has a couple b20s at his disposal, shall i just drop one of them in? Or shall I try to do as you suggest Uniberp and take off the head and do that stuff to it... I'm not sure, but just swapping engines may possibly be cheaper and easier. And then i'd have this engine to mess around with,(take apart and dissect and get rebuilt nicely), but that wouldn't be until i had some major time on my hands(not until next summer) and some money and a place to play with it...

More ideas? Thanks guys!
