Riddle me this!!
So my engine has been consuming a pretty decent amount of oil, and she smokes like a chimney when it cracks into VTEC. I feared for the worst, so i did a compression test last night...
We are dealing with a stock GSR bottom end, and a new, fully built b16 head with less than 10k put on it.
Since the head was new, I feared for the health of those rings. I pulled the plugs, all looked clean except for cylinder 1 which was oil fouled, and very crusty. Seeing only the single plug looking shitty, I was starting to feel optimistic that the bottom end might be ok.
Now for the compression, starting at cylinder 4 (saving that dirty cylinder for last) was 190psi, cyl3 @ 190psi, and cyl 2 @190psi... At this point I believe the rings are ok and im thinking I have a valve seal issue. I go to test cylinder 1 expecting to find a significant drop in the numbers....
Cylinder 1 tested at 210+ psi..... I cant for the life of me figure that out... The only thing I can think of is that the chamber is so full of oil crusty s**t that it could bump compression.. but that doesnt tell me the problem.
Any ideas/experience anyone?
