I rebuilt the oil cooler on a 95 F350 because the orings had gone out. I changed the oil in the truck as well. When I drained the pan I got about a quart and a half of antifreeze out of it. I got the truck to crank and it ran perfect for about 45 seconds to a minute. The oil pressure gauge dropped to nothing and now the truck will not crank up. I have already checked the port above the oil filter and am getting oil to come out there. I have also pulled the resevoir off and there is no oil at all in there. I even spun the motor over with resevoir off and no oil will come up. Sorry for the long post, just trying to be thorough. Please help. [img]/ubbthreads/images/graemlins/shrug.gif[/img]

Low pressure oil pump is gone? Not pumping oil up to the HPOP resevoir.... Be my guess.
Also this is in the wrong forum, there is a 94-97 forum for the OBS trucks. But this part is pretty much the same on both I think.

Just thought about this one......you said water in oil right?.....you get that in there doing the cooler ?...if so, maybe the engine oil filter has stopped up with water. I know the engines we have at work have a stacked paper type oil filter that will stop up from water VERY easy. It takes a lot of debris to stop them up , but just a little water/antifreeze. This would cause the low/no oil pressure.
Just a thought.
check the engine oil level , and to make sure its clean, no water/antifreeze. If its good, fill the hpop back up with oil and restart the truck.If theres water, change the oil and filter again. Maybe you just got a airlock? I know it wont start without oil in the hpop res.
Thanks for the replies. I changed the oil and filter. The antifreeze was already in the block. I am going to get a cheap pressure gauge and run a check on the port in the block and see if it has any low pressure oil. If not, I believe the oil pump may have went bad. I know now this is in the wrong forum, but my truck is an 01 so I didn't think of the year I was working on. Sorry
