What the he77 are YOUR thoughts?
I'd say it appears as though oil ain't able to go south from the head. Only you know how you installed the head gasket.
Buy yourself some new bolts this time around.

Im stumped and freezing like a popsicle in an open air shop... ok all joking aside..
My thought is the bypass in this pump is jammed too, for a reason i have no clue. My other thought is i probably don't have a blockage at the head gasket since i had excessive pressure at both locations.
Just got the pan off. Didn't see any crap in it. Fixing to pull the oil pump and take a looksee.

If nothing is wrong with the pressure regulator and if you are certain all is well with the headgasket, I'd put in the cheapest sythetic oil you can buy (I wouldn't even buy diesel rated stuff unless it was cheaper) and see what the cold pressures are.
My understanding of the oil system is that there are no passages to block if the headgasket is installed correctly. Basically some pressure bleeds off at the mains, some at the rods, some in the lifters etc and then it trickles back into the pan.
The other thing I would check is to pull the injectors next to the oil feed passage and see if they are covered in oil. You might be pressurizing the oil system with combustion gasses.

Post a pic of your head. I had an 85 built car ME that was hydro. VW never was one to do something simple.
I bet something amiss with the HG or Head itself. It maybe needing pressure tested.

Yeah i just double checked. Oben is up on the head gasket.
Jumping to your last idea... does this actually happen? And what would the leakage path be? Bad heat sheild?
I will say even with a professionally rebuilt pump from a reputable shop its hard as hell to get to start after its been sittijg for 8 to 12 hours. Ive been cheating and using a shot of brake cleaner to help it fire up. I was figuring one of my injectors was just leaking down and was going to replace them once i got the oil pressure figured out.
Im guessing my relief is probably stuck but am at a loss for how. Im pulling the pump next. If the releif is working what you say about combustion gasses is definately possible.

I don't think it would have anything to do with the injectors. There are no oil passages right by the heatshields that I know of.
Basically rather than the head gasket leaking into the coolant it found it's way into the oil. I'd say it's highly unlikely as I've never heard of it happening before but you did reuse your head bolts so anythings fair.
You might want to consider installing a 30mm oil pump rather than the 36mm one you put in there last time.

I meant to say the head gasket was for a mechanical head. My mistake.
Looking at your head, you have the correct gasket.

Ok...
Problem kinda solved. Bypass was stuck again. On the last one i didn't try too hard to get the shuttle valve out this time i did.
Put pressure on the inlet side of the relief port, nothing passed... removed end cap and spring, drilled a hole in the elbow so i could drive the shuttle valve out. Found some *** in there, and some heavy scoring along the bottom of the bore...
So this crap is floating around in the oil, and getting trapped in the relief port...
And until i get all this crap out of there it will happen over and over due to the design of the port...this is because the releif is in the bottom of the pump, high pressure oil travels horizontal and the exhaust is on the top of the port meaning unless there is enough velocity to expel the crap it just sits there. Even if there is enough velocity it just circulates between pump inlet and relief port...
I need to figure out a good way to clean this *** out. All i can think of is lots of brake cleaner up top and let it drain down as well as douch the hell out of it from the bottom.

Diesel/gasoline from the top.

You might want to check a bearing or two, the oil flying by at 200+ PSI can scour material off them.

Top end and rotating assembly really doesn't look too bad compared to the pan...
Pan... the glistening says all.
Didn't have any diesel so i dumped a couple quarts of gas in the top...
Im going to clean out the valve cover, the pan, spray a can of brake clean up at the rods and pistons and put another used early pump in it and see how it does for a few days. Im going to leave the high pressure gauge connected but put it in the cab and keep an eye on an upward trend. I just bought a new pump today but would hate to ruin it too....
Im not going looking at the bearings... i only need to keep this engine together a few more months. Just long enough to rebuild one of my cores.

No... grey mk2 recaros and cabby dash swap. Its bmw leguna seca blue. While i was painting the truck figured the valve cover, intake and timing cover all looked aweful so i sprayed them with the same base/clear as the rest of the truck...
Got it back together. One of the gauges is jacked though because the one labeled f is the filter flange and the one labeled h is the head. Im guessing the head gauge got damaged when it was pegged. But i will keep an eye on the pressure the next few days and see what it does..
