My trusty S55 diesel has been apart for more than a decade after suffering a catastrophic failure due to a clogged pre-combustion chamber. I have done a complete rebuild and wanted to build some oil pressure before actually firing the engine. I turned the engine over with the starter a zillion times and couldn't get any pressure, pulled it with my OC46 to turn the engine over-still no pressure. I have a long list of things that I have checked and found everything good (yes I swapped oil pressure gauge). Finally I started the engine and ran it for 30 seconds and still no pressure. I have done this a couple of times but have chickened out fearing bearing damage.
My question is: does it usually take a long time to build pressure on these engines? I don't remember it taking this long even when changing the filter. I can get oil flow at the filter and pressure relief valve (spring and valve are new, $60 yikes).
