So I can drive the car all I want without nitrous, but when I put nitrous to it there is a lot more of a leak. Suggestions? Blowby?

 

I notice the same thing with my car. Wonder if its added pressure because of the jump in power causing oil to blow by the rings. Is it burning it or leaking?

 

Where is the oil leaking from? As noted, excessive blowby will cause crankcase pressure, causing leaks. But a correctly assembled engine, using the correct parts, should not see a large increase in blowby when spraying. I'm spraying a 300-shot, run a totally stock LT1 PCV system, and don't have any issues with oil leaks.

 

Coming from the oil pan gasket. I am about to go RTV the crap out of it before the next trip. I have had issues with my stock oil pan since I put the motor together with occaisonal leaks though. It could just be leaking again. The stock pan I had to hit with a hammer a good bit to fit around the new crank and 4 bolt splayed main. It just seems that when I spray there is a much bigger puddle where when I don't spray you can rarely see any under the car after racing.

 

Check the PCV system.

 

How do you know it's leaking when you are on nitrous?

 

Injuneer, PCV and Brake Booster systems I need to check (brake booster because when breaking at low speeds the car tries to die). I do think my oil leak is related to the PCV system though. I have been looking through shoebox's site a little and havent found a good way to test them. Any ideas? I have been doing searches here too for the PCV, cant find good info.

Re: oil leak under nitrous only
Check the PCV system."

Absolutely! If the 96s have the same PCV setup as 95, especially check the PCV line at the front, bottom of the intake manifold. Mine had an 'old style' reinforced rubber 90° elbow between the manifold and the 3/8" steel line. Over time it hardened up and became a very loose fit and leaked enough PCV oil that I thought I had developed a serious timing cover leak from one of the seals. After I replumbed the PCV system using a metal elbow at the manifold and a knock-out trap on the line my seal leak 'magically' stopped.
