What's the deal with this? It seems to foul very quickly. I was attributing it to my other issues with starting and running smoothly, but I just pulled it again for like the 3rd time in 200 miles and it's fouled. Rings? Big job? Expensive?

Id look at the valves and compression first.....
does it smoke?

I have the same issue with my #2 plug but it takes like 1000+ mi. I am going to replace my valve stem seals first and while I'm in there I have some new valve springs off a 350.
zero smoke...this plug keeps coming out with the gap bridged with junk...
