Compression Test...

well you could run a compression check but oil in the cylinder could be valve seals, rings, etc.... does i smoke bluish ever?

or you could be lazy and run a slightly hotter plug

Yea not really noticeable in the exhaust....like maybe a little blue...i made a you-tube vid earlier...and revved up the exhaust..and there was a little black smoke..and i think some blue after that...here is a link...the exhaust part is at( 1:17 ) so if you skip to that you can see the smoke shows at about 1:23-1:30 when i rev...its not continuous though only when i rev......
