96 HPOP leak...

Ok so I just picked up my 7.3 and vally was full of oil. After cleaning it out I was able to determine that the oil is dripping off the bottom of the HPOP, Im not sure if it is the Non servicable plug or the Flange Gasket. Im leaning toward the flange gasket becasue i put a paper towel wraped around a piece of wire under the HPOP and it seems to be getting fresh wet oil under the HPOP but not under the plug. If the plug was leaking do they usually leak bad/fast?

I am going to be dissasembling the Truck today to get the HPOP off. I ordered an O ring kit ---> 7 3 Powerstroke Complete Hpop Repair KIT W Long Thread | eBay

And a new flange gasket ----> Ford 7 3L Powerstroke Hpop High Pressure OIL Pump Injector Pump Mounting Gasket | eBay

Is there anything I should know befor digging into this?

Is there a write up on how to do this the best / easiest way?

Im new to diesels but I am very mechanically inclined. Excuse my grammer, it is not one of my strong points...

Thanks for the help guys.

P.S. please help me so I can get this thing fixed for labor day weekend, I need to tow this --->

Dieselorings.com has good instructions on how to do it. Not really that hard, just time consuming and aggravating.

Get a couple cans on brake or carb cleaner.

From my experience when the plug goes it goes with a lot of oil. Not just a little drip.

Ok cool, yea it seemed to drip durring the high idle setting on the programmer. It could get worst while driving. I figure im going to replace the non servicable oil plug anyway becasue its going to be out and i only feel like doing it one time. Considering it has 245,000 on the block i hope that if this pump was removed befor the mechanic didnt strip any of the small bolts...

I did the same when my plug started leaking. Resealed the whole top of the motor. Hpop, oil lines, turbo, fuel bowl, gutted ebpv, etc.

You gotta take it all apart anyway, why not knock it out at once.

Use a pump to empty the reservoir as much as you can before removing the HPOP. I saw a thread where someone actually used the pump from a hand lotion bottle. Whatever works!

Not a necessity but definitely keeps things a lot cleaner. Keeps you from draining a quart of oil down the back of the block.

OK so after cleaning the pump up really well. I was inpecting the mating sufaces from the pump to engine. On the pump there seems to be a few tiny (a few thousanths deep) marcs in the mating surface where the gaskets rubber ring sits. Should i put very tiny dabs of permatex in these little spots to fill them up? Permatex is rated for 10,000 PSI when applied between 2 clamped surfaces... I do not want a leak but at the same time I do not want to cause myself more issues...

I don't think it could hurt as long as you don't over do it.
