Message: [QUOTE="Garbage_Mechanic, post: 1518475, member: 1610"] I would pull the glow plugs and spin it over with the IDM fuse out or the VC plugs unplugged. I have a routine for this that is a bit tedious, but I think heads off a lot of issues that we read about with newly assembled engines or engines with new injectors installed. Here is my routine: Assemble the engine as normal except do not install glow plugs. Leave out IDM fuse or disconnect valve cover plugs. We want to "motor" (spin over) the engine without compression overheating the starter and more importantly loading the rod an main bearings without oil pressure. With an OBS that still has the original mechanical fuel pump we also prime the fuel system at the same time. Less important with electric fuel. We do not want our new injectors firing with no fuel or aireated fuel. The next prep item is to loosen the #2 orb Allen head oil rail bleed screws under the valve cover. They should have had new o rings put on them while things were apart. If they haven't been apart follow this to get them loose: DO NOT attempt to remove the plugs by just sticking an Allen bit in there and torquing away. The bit will snap 9 out of 10 tries. Use a flat ended punch at least the diameter of the plug head, or alternatively the largest flat ended punch that will fit in the Allen well and strike the head of the Allen plug hard 2 or 3 times. You aren't going to break anything. This works for all flush plugs in aluminum, iron or steel castings. HPOP reservoir plug especially. Now remove the foreword most (highest) oil rail plug. Leave the oil pressure sending unit on top of the HPOP reservoir ( for lube oil pressure) installed but loose so air can escape but an oil flood wont sneak up on you. Continued [/QUOTE]
