well all cars get some fuel in the oil....I think the bog is cause of several things...maf may be too small...mismatched parts not working together...timong in the advance is not coming in on time, too big injector for which a tune is needed to match injector pulse,pressure and timing....exhaust too small ie stock...t/b too small..etc.....I would however start with a tune up and a hotter coil, and set base timing without nitous at 14

thanks for all the replys, I have a granetelli mass air for 30's, 255 fuel pump, fresh tune-up cause i just put the motor together, and 3" exhaust. I was thinking the injectors could be staying on also, The fuel mostly shows up on or by my breather, the oil on dipstick don't look to bad, but if i smell inside my valve cover hole, it smell's like nothing but gas.

if you've got a rich condition and too big of injectors you might be having some blow-bye issues and the fuel is washing down the cylinders into your pan

sounds like you need a good dyno tune for the EEC computer

just to make sure you understand......
when we are saying a tune, we dont mean your standard
mechanical "tune-up", but a custom EEC computer
re-calibration.
You're really supposed to tell the EEC if you
increase displacement
change MAF
change injectors
and have a dyno run to tune out all the WOT and partial throttle
mixture and timing. Lots to it.

EFI is great but if you change from stock
anything you really need to go into the computer
have it adjusted after some dyno pulls.

your injectors are too big.
I run 24#ers and for a 13-1 air/fuel mix my pressure is set at only 29psi.
for the nitrous I set it at 34psi and it is still overfueling.

I have a 308 with AFR heads and b-cam and 1.7 rr's and edelbrock rpm2 intake.
my compression is around 9.2
24# injectors will support 475 hp at the crank.
