Sludge on Plug #1
When I replaced spark plaugs about 2500 miles ago, I had some sludge built up on plug #1. Every few days I was checking the new one to see if everything looked ok. For the first two weeks there was no build-up. Well, I have been experiencing some new roughness after 3 400 mile RT trips and I decided to take a peek. This morning I found that the plug had the same sluge built up on it. I checked my oil (mobile1) and it went from a honey brown to a deep black over the last 800 miles or so. That'* about 2500 miles.
What I'm guessing is that I've got oil getting into that cylinder. Is that a fair conclusion to draw?
What do I do about it? It seems like it'* pretty slow to only show up sometime after a couple weeks. Is it possibly a problem with the fuel injector? If there'* no fuel to spark or not enough, it wouldn't burn any oil that'* in the cylinder and it would build up slowly like it is. Of course this is all uninformed conjecture. I need someone to step up as Matlock, I think.
But, I think I have found something that'* causing my engine to feel like a deisel. Whether this is causing my highway quaking is to be seen, but it seems l have a likely suspect.
