This is really weird. Sometimes you can start the car and it won't smoke at all. Other times you start the car and it smokes quite a bit. I noticed today driving that the oil pressure has a slight fluctuation on the highway. Pressure on the highway was about 50-60 psi at 3000 rpms. Then, when I got home, and the car got to idle the pressure dropped to nearly 0. I immediately shut the car off. I checked the oil and it appears to be right on the full mark. Looks like at low RPM's that it goes to pretty much 0 but pressure is fine at speed. In case you are not sure, I am talking about oil smoke. Here's what is done to the engine if it may help trouble shoot it at all:

B16A block, not sleeved
JE forged pistons
Eagle H beam rods
Bottom end balanced
B16A head ported by DH Racing
Custom turbo cams by DH racing
Currently has a stock exhaust manifold on it.
AEM rail, B&M retro fuel regulator
Venom in tank pump
Stock injectors at this time
PR3 ECU
Last bend for turbo is currently just a short ram cold air intake.
3" mandrel bent exhaust with Dynomax SuperTurbo muffler.

Turbo is not installed and never has been. I wanted to break in the engine before I put on the T3/T4, DH Racing log manifold, etc.

What worries me is the fluctuating oil pressure. At first I was hoping it could just be a bad PCV or something. Any ideas??

OK. Let the car cool down and changed the oil. Oil was clean but did look to be a little thin. Did not smell like gas, though. Put new oil in and started the car. Pressure used to be around 62 psi at 3k rpm. Now it's about 42 psi at the same. According to the electric Autometer gauge, the pressure drops to 0 or nearly 0 at idle. Engine does not make any noises when the pressure supposedly drops to that point. Car did not smoke on start up, during the drive, or afterwards...

check your timing. i have friend who have advanced it and it smokes because of it. just a suggestion
