08 econ stand pipe check valve

[lraffe1]

I have a hot nostart o8 econ. I verfied no oil pressure and that ipr is working. I then contacted hotline and they say all 08 and up econ 6.0 have the updated stc. So I take there word and pull valve covers and air check. By this time it has cooled down and i cannot find the leak. I then remove dummy plugs and they appear are ok. I then removed stand pipe check valve and the right side is in two peice. I don't know if anyone knows this but on the updated check valves the darker colored piece with the o-rings on it is threaded in and retains the spring. I then removed pipe that connects to branch tube and removed remaning pieces of check valve. I then contacted hotline and they said to replace stand pipes assemble and retest. However I am wondering if check valve could have backed apart when removing and there is a different cause of conern. Has any one had pump cover off 08 and up evan and do the have the one piece stc. i have worked on aleast one or two evans a weak for three months straght and realy (realy!!!) do not want to take this thing back apart.

The new one piece fitting is installed in V8 engines beginning with engine ser# 431736 built on or after 2/9/07. If the vehicle build date is close then I would HVBOM the VIN and get the engine serial number and build date.

I had a 2010 E-Series that the two 8mm bolts on the branch tube connector had backed out, causing a hot no-start if it helps.
