That's a good thread over at m.net. I do not think that any combination of head gasket, head and block would cause coolant to leak.
Have you pulled the head yet? If not, check head stud nut torque beforehand- maybe you did not have enough spinach that day?
:| Also I'm sure it's on your list- head and block flatness. I think those two things are the likely culprits.

I believe that the block is flat. As I asked the machine shop to check that and they never told me it was not.
I did not actually have the head checked by a shop. I will see if I can find anything at the house to do a rough estimate of checking if it is flat, and then I will see if I can find a local machine shop to take the head to to have them check it out.

That is how the head gasket was on when I pulled the head. So it was definitely on correctly.
That is with the head gasket flipped around the only other way it fits on and that is definitely not correct. I am going to find a shop tomorrow to check out and make sure my head is flat.

Do you have access to a carpenter's square or a 2-foot level? They might not be as perfectly flat as what a machinist would use but they should be good enough for you to do a quick check. Basically check it lengthwise, widthwise, and diagonally. I'd think any warpage that's bad enough for the HG to not seal ought to be evident with either of those tools.

I got the oil pan off today. Nothing looked to bad. I will probably be pulling the oil pump apart tomorrow. I need to go get some torx bits for it. Also I noticed I need a new front main seal.

Was 60ft/lbs on all head bolts like the factory manual says. I will agree pistons were dirty. They have now been cleaned and cylinder walls look fine. Hopefully I can pull apart the oil pump tomorrow and find something wrong and get this **** fixed. I miss boost so much.

So that is the picture out of the FSM of the oil pump. I had what what circled in blue. What was circled in green was not in my pump. so the little rubber thing could move freely up and down. So I am pretty sure that is why I would not build oil pressure. I am pulling my oil pump off my other motor tomorrow and will compare the 2. I will most likely be putting my billet OPG in the OP I pulled off my old motor and then starting to put the bottom end back together.

250 RWHP brought to its knees by a small spring and retainer...
Would it have been possible to get to that spring/retainer without removing anything other than the plastic undertray?
shuiend, make sure the billet gears and oil pump dimensions are of the same generation.

I am 99% sure my OPG are for the correct year OP. Mostly because I bought them in the original group buy years ago before we realized VVT OP were different. I will definitely be checking clearances today before I put the bottom end back together.

I ordered a new head gasket and amsoil trans fluid today. Was to lazy to actually do other work on the car. Will be hitting it hard tomorrow to try to get this thing back together.
