[cgarr]

This was my first set of VW heads that I did but I do pretty good head jobs, at least on Porsche heads. I don't think its a valve, not much time today but pulled the rockers and no bent pushrods and all the valves do work when tapped on. The crank only moves about 5 degrees each way then hits a very solid stop. I think a rod snapped right at the crank! as far as the popping noise that could have been one head leaking at the cylinder seal after it over revved, I had this happen before and it sounds just like it. Should have it all apart tomorrow to see... Really nothing much in the oil screen either, had one little metal flake and nothing around the screen...
