Post initial start up....could use some help

[FLYNAVY30]

A little bit of back story....1972 C20 Suburban. I built an LS1 using a 2002 aluminum LS1 short block that had been rebuilt using the factory rods and pistons but with new rings and bearings that I purchased from a local guy. I had a set of 243 heads that I sent to TEA to be cleaned up and milled to 62ccs that results in about 10.9:1 compression with the factory flat top pistons. Cam is 216/224 585/585 112 LSA. Everything else in the motor is new. ARP hardware throughout, Holley oil pan, ported LS6 oil pump, Holley front accessories, all new gaskets throughout. Eddelbrock intake, Holley 650 double pumper carb, MSD 6010 ignition box, painless wiring harness. Trans is a rebuilt 4L60E with FAST TCU.

On initial start, using the #3 pill in the MSD box, the motor fired right off and settled into a decent idle for the first start. That was followed shortly by oil pissing down my leg as the fitting on the rear of the factory oil pressure gauge was not correct. Following correcting that problem, I was showing solid oil pressure and had multiple start ups and shut downs while troubleshooting a number of gas, coolant, and power steering leaks.

Having sorted that out, I finally had the opportunity to fire the motor and allow it to get up to operating temp. After running for a few minutes (I took the below video showing some of the residual grease burning off the headers, but note the excessive smoke/vapors coming from the valve cover breathers https://www.youtube.com/watch?v=qUEq...ature=youtu.be) , I noticed that oil pressure was showing zero and water temp had pegged, so I quickly shut the motor down.

After allowing the motor to cool, I popped the valve cover, and found this....generally doesn't look too bad, but some black globs....all oily residue, with no significant substance.

I then very briefly fired the motor to verify that there was in fact zero oil getting to the top side of the motor. I then drained the oil and the filter. There was no metal particles in the filter, nor in the oil as I ran a magnet through the pan repeatedly and got nothing more than a slight film on the magnet. That being said, you can see in the video below that the oil, which has about 30 minutes of run time on it in total, has a slight sheen or milky look to it. I did check the coolant, and while I did burp a significant amount of air from the system, all of the coolant is 100% clean.

Any input as to the loss of oil pressure at this point would be greatly appreciated as Im pretty much dead in the water and out of ideas.

Thanks very much!
