I have a stock 12a with a stock oil pan and 106,000mi. I notice during autocrossing with long right hand sweepers my oil pressure drops and the engine exhaust smokes some. I run the oil at full factory level. I can solve the oil pressure drop with an Accusump. Is the oil smoke another issue altogether?

 

I dont know about the smoke, but you can help prevent the pressure drop with an oil pan baffle from Racing Beat.

 

The stock pan doesn't really cut it for hard turns. Weld in some baffles or get a baffled pan. You can spin a bearing in no time if you starve the engine of oil.

 

So the exhaust smoke is a result of oil not baffled in the stock pan flowing up into the engine on hard right turns and likely not another issue?

 

Quit making right turns!! for gods sake!! I just had to raz you a little I actually have no idea why that's happening but....My friends old CramArrow would pump out blue smoke for about 3-4 miles when on a road trip only doing this about every5-6k miles we took the engine apart rebuilt it and it still did it !! never did figure that one out ??! I do wish you luck on finding the answer and hopefully i'll see the answer gl with your car!!

 

In turbo rotary cars I have experienced smoking on hard right turns (under throttle) when the oil climbs the filler tube and blocks the path for the blow by gasses to get out leading to a pressurized crank case.

 

Can you run a vent tube on opposite side of the engine? Gasses will take the path of least resistance
