What do you mean by Solid? Something is burning if your seeing smoke. Like you say maybe the pistons where burned out already. or starting to, Since #1 a 12:1 engine you have is not tuned yet, probably getting too much gas which in turn burns out your rings.. Which is very possible..

Cant run a built motor on a stock ECu or a "base Map" for long..

So if it's blue your burning oil. might not be much but it's doing it somehow..

- Sun Jan 01, 2012 7:52 pm #288067 but if i was burning oil in the cylinders it would show up in a cp test and my cp ratio is 245 in all 4 of them and iam not losing any oil on the dip stick at all . now what i think the prob could be is this .
b4 i got my vavle seals done it would burn oil for about 6 months i think there is alot of reidue build up in my exhuast from be burning oil when the vavle seals were bad and iam getting an new exhuast tommrow a apexi ws2 and hi tech header so we shall see

are you doing your cp test cold or hot? throttle all the way open? are you unplugging the ecu (or atleast pullin the fuses) and all that jazz too?
