this is retarded, please help!
ok this is gonna be long, bear with me....my set up is a turbo b16 crx with turboedit, i have had one consistant problem ever since the turbo install, i get fuel in the oil, and its become very frustrating, at first i thought it was a crank case ventillation problem, because i had the pcv system set up stock, with the valve cover breather open, and i thought maybe the crankcase was building pressure under boost allowing blow by, so i removed the pcv system all together, and the hose that used to go to the pcv valve no longer has a pcv valve on it, and is just vented to the atmosphere, this way, there is no possible way that boost is getting into the crankcase, so i have eliminated that as the problem, next i think well, maybe the rings are shot, but on a dry compression test i get 165-170 psi in all cylinders, now i know thats not GREAT for a b16 motor, but they are all consistant, and not terribly low, so the rings seem to be OK....next i think well, maybe im just getting so much fuel in the cylinders that its blowing by the rings like crazy, but im running dsm 450's with turbo edit and a plx wide band, i have it tuned decent enough that i get 14:1-15:1 afr's in vaccum and consistant 11:1-12:1 afr's in boost, which leads me to believe its not just being loaded up with fuel...last night i changed my oil and put in 4 quarts, which brought it up to the bottom dot on the dip stick, i drove it about 40 miles, and boosted on it hard through 1st and 2nd 3 times, and now this morning i re check the oil, and its above the top dot on the dip stick, like it has 5 quarts of oil in it, but it has to be fuel, and i THINK it smells like fuel, but its hard for me to tell, and i dont see how it could be anything but fuel, wtf is going on? am i wrong in saying that its not the rings since i still have consistant 165-170 psi in all cylinders dry? im at a loss here, the only other thing i can think of trying is a stock pr3 ecu, stock injectors, a missing link, and an FMU, and see what happens then....but i dont think thats gonna fix my problem, also its only been boosted for about 500 miles, thats why i dont think just ripping the bottom end apart and re ringning it will help, because i believe theres something else causing this, but what the ---- could it be
thanx for any help guys...

hmmmm i dunno it smells like fuel, but whatever it is it wont catch fire on the dip stick, even a smell amount of fuel like 1/2 qurst mixed with 4 quarts of oil would catch fire on the dip stick? and my radiator is full/clean coolant, wouldnt it be low/dirty mixed with oil if it were coolant from maybe the head gasket?

Re: this is retarded, please help!
before you trouble shoot you have to make sure thats actually fuel in your oil ( which doesn't sound very likely, wideband i would think would show sparatic dips in a/f ) drain the oil into something with a top and let the oil sit, fuel i think would sit ontop, or you can try the flame to dipstick trick.
If that is fuel i'm at a loss of how it got in there without effecting fuel mixture

i do have dips in afr's between shifts, it will dip down to like 12:1 but it's only for a split second between shifts, i thought this was normal, as i have heard other people say they saw the same thing on there wideband between shifts?
