Re: Symptoms of a burnt exhuast valve?

If you wiped lobes, there was a lot of metal that went through the engine. Pull your oil filter and cut it in half so you can look at the element. If there are metal particles, there is a good chance that they have damaged your crank and bearing surfaces. Probably worth your while to pull the engine to at least look at the bottom end and the cylinder bores (you are going to have to remove a head to have it repaired and would normally do both heads at the same time). Sounds to me like this could be a more extensive than a cam and lifter replacement. Good luck with whatever you do.

Thank you, you are absolutely right, its looking like this old engine has seen better days. And considering that I really don't want to put much money into my old heads, since they have the small 1.72/ 1.50 valves. I'm quickly moving towards just buying a new gm crate engine.

Oh, and ill go ahead and check the filter, but I changed the oil and filter about 500 miles ago, right when this problem first crept up. So it might not tell me much, or I might get a false indication from the filter, but I'll go ahead and give it a look
