Well another update. Got a fidanza adjustable cam gear and degree'd up the exhuast cam. It was 11 crank degrees off, or 5.5 cam degrees. I installed the ATI Hub for the damper. Also installed a Kiggly racing HLA regulator. Oh I also tried some of the copper spray a gasket on the head flange of the manifold, IDK its different haha, I was thinking the copper might hold up to the heat and if nothing else it will delay the rust? For some odd reason my ETS manifold has a mild steel head flange.

Well guys It has been a long time since I last updated. The car is running great, and finally has enough break in miles and oils changes for me to feel comfortable abusing it haha.
When I 1st got it together I noticed a few minor oil leaks, one from the oil return line, one from the sending unit of my oil pressure gauge, and one from a crack in the valve cover. I tried numerous types of thread sealants and couldn't get the sending unit to stop leaking, i finally just removed it and installed the factory plug. i think the thread pitch was off on the 42draft designs adapter I was using.
I am gonna spend some time on the car today, I need to fix a few boost leaks and change alky nozzles for the tune, also need to give the wastegate some attention as it seams stuck closed from sitting for so long. Wellllppp thats all for now!
I need someone with a quality camera to get some good photos for me.

I found your problem, it has a FRAM oil filter AKA orange filter of death (not kidding)
Not trying to be a smartass but if you do research they have caused tons of issues (personal experience of my friends truck too) they use like a cardboard end gap glued to the end of the filtering media and a stamped piece of steel to ACT as a spring. Plus more stuff I forget, but thats enough for me to never use them, It's horrible cheap engineering though. On my friends truck we were leaving the mall one time and it started clunking and clattering and we look down and had NO oil pressure. Had plenty of oil and figured out it was from the fram oil filter, changed the filter and had oil pressure since.
Also the egg shape wear in the front cover can also be from having the timing belt too tight, the egg shape wear points towards the 10 o'clock area (top rear of engine) right? I've seen SO many people not know how to adjust the timing belt tension Correctly. After you set it and lock down the tensioner and spin the motor over a few times (also to verify the timing is still lined up) then you wait at least 15 minutes(to give time for the hydraulic tensioner to adjust) and you should still be able to put the grenade pin in the tensioner hole. If not then it's too tight or too loose. If too tight it will cause the exact problem you had, there was a thread on here somewhere that it happened too and he had pictures of everything including the eggshaped front housing.
