BOUGHT A 95 PSD(275k) with not knowing any history on the truck. It ran great after 2 weeks of driving got around to finally changing the oil. Familiar with diesels so I used the Shell Diesel 15W30 oil. Ford filter. Oil was fine that came out dirty of course. Heres where the fun starts 2 days later was planning a taking the truck on a 80 mile road trip. Everything running great till bam driving 50 mph and the truck just shuts off on me. I couldn't get it started for nothing. Towed to local shop(small Town).
Local mechanic says it a fuel problem. I say ok fuel pump $400. still doesn't start new seals on gas tank ($100) MORE. Still no start .
I get a replacement IDM (bought online) gave to him... Still No Start.In his shop 2 more weeks he want to put HPOP , for some kinda crazy *** money. I say tow it to my shop. let me figure it out.
I replaced IPR.CPS. still no start. Finally wore out the Starter. New Starter installed... definitely help turn the truck over faster. Finally I read about HPOP reservoir and checked it. Its bone dry. I pull oil into it a the required level.
go out and try to start .
Boom after cranking and cranking it comes alive, but running on what seems like 4 Cylinders.
Then the oil start pumping up (Valve covers were off from checking Wiring) and i see what appears to be a tan Milkshake mix only on drivers side. No oil spurting on Pass side.
Shut down engine. Play with pass side injector wiring.. restart and now both sides pumping the Milkshake mixture.
Immediately shut down again. do my research thru this forum and hope that its a OIl cooler issue. Coolant doesn't look milkshake but its old and rusty looking. New seals ordered. Took a couple of pics of the oil cooler.
disassembled the seals didn't look to bad but were hard.

I cleaned every thing up degreased flushed. Powdercoated oil cooler while off.

I'am looking to get some expert help trying to figure out if its my head gastket Is blown or maybe I'll be lucky and its just my oil cooler.
What about injector cups. could they do this?
I hadn't put the resealed oil cooler on yet with out getting a few opinions.
Any help would be appreciated!!

Most likely the cooler seals. Injector cups usually result in fuel in coolant. Before you reinstall your cooler, make sure the oil pressure regulator and filter bypass valve parts are in place (they like to fall out on the earlier models that don't have them snap-ring retained. Cheers!
