I have never had one get hot since the engine spins free. Another way to check on LPO at this point is to pull the lube hose off the turbo and put into a clear bottle. Should see oil flow here, this is straight off the main bearing supply. (just another benefit of doing this, you know the turbo has lube before firing it up....) I've never seen it take too long to get LPO up, if say 10 mins of spinning it over has gone by then there is an issue with the pickup tube or something left out draining all the LPO back to pan. That is another post / thread. Assuming LPO is now up, be sure HPO reservior is full, turn on key with injectors disabled, remove the HPO rail bleed plugs if not already out and crank until steady oil comes out both plugs. Reinstall plugs. Reconnect injector plugs or IDM fuse. Spin over for 3 seconds to a minute, now working the last of the air out of the injectors them selves. Don't do this too long or you will get excess unburnt fuel in cylinders. You can see if fuel is getting injected, it will come out the glow plug hole as fuel vapor while cranking. Now reinstall the glow plugs. While you are doing this might be good to charge the batteries. Be sure all plugs and fittings are installed tight, everything ready to run. Now let the glow plugs cycle watching to be sure the cut out like they should. The engine should now fire right up after a very slightly longer than normal cranking time at most. It should run like it has not been apart except for perhaps some extra fuel / oil smoke from injectors being out if in service engine, if new very little smoke. No need to slam brand new injector pistons around due to air in fuel and oil systems, and no need to have to "drive it lie you stole it" to get the air out of the HPO system. Last set of injectors I put in using this procedure I started it up, looked for leaks, letting it idle while I put tools away, shut it down, rechecked fluids, installed air intake, washed up, changed shirt, loaded family in truck, wife driving (her truck) and went to Saturday night dinner. Not one hiccup. [/QUOTE]
