I had the exhaust rigged so i could somewhat breath in my garage.

spark plugs are clean

bummer, looks like it might be time for a turbo, or time to inspect it at least.



make sure the oil return line isnt plugged or anythign too (for the turbo)



though since you're premixing note that it will be smokey when running rich, like premix smoke, not typical running rich black smoke... but you seem to have visible oil leaking from the exhaust, and said you have seen an oil drop from the dip stick, not cool man.

There is oil leaking from the backplate of the turbo, My car was low by a quart also. But that could have been from my oil cooler being empty when i put it into the car.. When i hooked up my stock oil pressure guage, its through the roof, like 130psi. The turbo is also smoking/steaming, i opened up the return line on the turbo and oil was coming out... I am running premix, but there seams to be way too much smoke, I just emptied the gas tank, and now it has 2 oz of premix with the 2 gallons of 92octane..

my car smokes alot right now if i rev it. It may just be tuning.



the throttle pump values on mine are too high, if i start revving the throttle pump kicks in and it turns into rich madness, and i fill the neighborhood with smoke. I shut down, start back up, and it idles smoke free, i can slowly turn up the rpm with my hand, gently enough not to kick in the throttle pump, and it doesnt smoke.



Go to options the throttle pump, check out those values.



I know you got maps from a friend with a similar setup, but maybe you are running higher fuel pressure than he was. You have to realize theres oil in your gas now https://www.nopistons.com/forums/pub...DIR#>/wink.png

I'd say your pressure at 130psi is part of the problem...

1Revvin7 06-27-2003 08:54 PM

crankcase is vented to the atmosphere...

yea, lol. I am going to verify with a mechanical gauge.

I cannot get the damn idle down, and once i revved to 4k and it stayed there.... Throttle position at idle and that time was 4%...
