My car's leakdown test: good good good 60%. Meaning the fourth cylinder is leaking 40% through the ring(s) supposedly. When I did my compression test before my dyno run, I got 180 180 180 165, so the engine was already not performing at its peak. I'll do another in a couple of days, or maybe today, to see what it's at now.

So, is there ANYTHING I can do? Not really. I'm going to try out some snake oils. Anything you guys suggest? I'm planning on at least trying some "Restore" stuff, that I've used before.

Then again, Shayne says that most of the b20b's that he's seen have broken rings(or something like that) from the original integrated intake manifold with the secondary butterflies, so not much can really help that problem.

I guess this mainly explains why when I took out the plugs, the number four plug was really light compared to the others? Number three was a lot darker than the others...?

Suggestions? Theories? Thoughts?
