I know nothing about diesels, but isn't the oil pump like those in a gas engine? Just a set of dumb iron gears spinning in an oil bath - with some sort of spring holding a bypass passage closed until the pressure reaches a point that someone thought was high enough to burst an oil line or the oil filter?
It would seem to me that any pressure spikes or lows would come from the engine side - a flat spot in a bearing, or a warn component reaching a point in its travels where the oil can squirt out past the normal seals.
What did you discover was the problem?
As to joining the chapter - just run your curser over my signature. When you cross the line of trucks and the blue type talking about the chapter, the arrow that was your curser will change to a hand with a pointing finger. When that happens, just double click and the software should take you to the join chapter screen. If that does not work, pm me and we will do something else.

The high pressure oil pump in the PSD is fed by the standard oil pump. The HPOP has a reservoir and actually pumps oil from the reservoir into the heads to drive the injectors. This pressure is optimal above 2500 psi. Mine doesn't come close. I have an early 99 truck that has a 15 degree swash plate and the later ones have 17 degree plates for more volume and pressure. The hot ticket these days is to run dual pumps and get 3300+ psi right off idle. The downside is you're looking at $2000 to $2500 for these setups. In stock config, the oem pump works fine. But many of us are chipping the truck to get serious power out of them and one of the things that lags is the HPOP. If you've never browsed the 99-03 Powerstroke section of this forum then you should take a look through there. A lot of guys are modifying their PSD's because they usually are smog exempt, even where I live here in CA.

Thanks, FD - you have opened the door on a subject I have not thought about in 20 years. I am just now getting a grip on efi and computer engine controls for gas rigs - direct injection for a diesel engine is a new subject to me.
I have been around John Deere diesel tractors, and one truck I owned had a Catapiller V8 in it - it was impressive, fun to drive, but even back when diesel was a dime a gallon it was still expensive to drive.
There has been a lot of improvments to diesels over the last 25 years - I will look at the forum you suggested, and get a good basic understanding of the power stroke and then pick your brain, if I may.

Fat Diesel, welcome to the chapter! Nice to have a guy here locally that has a good knowledge of diesel engines. I've got one of the smogged diesels (6.0) in my newer truck. I have learned alot about the diesel engine through my job where we use mostly International Diesels, now with my PSD I'm learning more than I wish I needed to. They used to be so simple. Even from yours, my 05 has way more technological do-hickies to have to deal with. Oh well, welcome to the 21st century eh?

He got hold of a straight '85 with a 6.9 Banks turbo'd diesel with a blown head gasket and asked me to swap everything from his old truck into the former diesel truck. (I get the diesel. It's going into my '68 F250 eventually.)
So far I've got the engine/tranny and front suspension swapped in, the rear is getting swapped tomorrow (oh, look at the time...I mean, later today!) and then I can take my time to finish the wiring and fuel system plumbing.

Truck looks great though, I'd like to keep it for myself. (Except for paying for the gas it'll drink!) Other than the wiring there are only a few little details to work out. Then maybe I'll have time to get back to my Ranger...except that another guy wants me to shorten his Blazer chassis and drop a Land Cruiser body onto it, in exchange for which he'll give me two 1950 F1s. I guess I can force myself to work on a...a...oh, I can't even say it! Y'know, one of them there brand "C" vehicles, when the payoff is in Fords!
