#1 Plug fouls quickly...uh oh. (1 Viewer)

[NYNick]

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?

Ouchie!

Id look at the valves and compression first.....
rings...???
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...
