d15b7 compression check.
I did a compression test on a d15b7 with approx 245,000miles on it. I get approx 120psi on all cylinders with the engine warm and at WOT. I don't see any difference when it is not WOT. Is my intake manifold blocked? My sparkplugs have white stuff on them (running lean).

Running lean = likely to burn up rings and toast exhaust valves. Start by changing your fuel filter.
Edit: Oh... you were at WOT... don't know why I missed that the first time I read it.
With compression numbers like that vs. the miles on the motor, I'd say you're doing alright, but 120 is low.
