Maybe you can post some pictures of that valve. I don’t have a lot of experience on the 1.9TD but the on the other in line 4 cylinder engines the valve I am aware of is the oil filter bypass valve. This is a major difference between factory filters for the Waterboxers as compared to the inline engines. The Waterboxers need the bypass in the filter whereas the inline motors have it in the filter flange. Looking at the filter the oil flows into on the outside and then enters the engine through the center pipe. If oil is going through the outside of the filter flange into the engine then the filter is bypassed.

Progress!! Put the engine back together yesterday, and installed the oil filter flange without the check valve. Just by spinning the engine over with the starter, I got oil pressure at the head in about 10 seconds!
Today I have to bleed the coolant system (again) and then it should be ready to run. I am leaving an oil pressure gauge installed right now just to be able to see what is going on. I also spoke with Chris at Foreign Auto Supply in Maine. They also sell a TD conversion for the Vanagon. I asked them specifically about the check valve in the oil filter flange.
They say that they always remove it on the diesel engines they install. It is for the gas engines and that the diesels don't need it. That is good enough for me. This one little part has caused me more pain and delay than I would like to think about. Just not sure why the engine supplier didn't know about this issue.
Response from Overland so far has been to overnight me the bare essentials to put this thing back together. I sent them pictures of one of the cam bearing caps that looked galled to me and they said it was fine and I didn't need a new head. After cleaning it up, it really isn't that bad so I am not going to make a big deal about it since it is their warranty.
After everything is said and done, I am going to petition for some store credit for all of my extra time.
