hpop reservoir plug removial/ dipstick o ring

[illiniroper1]

I just bought a new truck and want to change the reservoir oil, but cant get the plug out for anything. does anyone know any tricks to remove it? also, the truck is leaking oil from where the dipstick goes into the oil pan. I've been told that it is best to take it to a dealer to get it fixed. does anyone know how much this will cost, is it worth is, or is it better to do yourself?

I know there is a plug on the HPOP that is not suppose to be removed but not sure which one. Also, there have been a couple guys on here that have had the oil leak down by the dipstick and have found the pan either rusted out or cracked there. I would clean it off and check the pan closely.

You do NOT have to change the HPOP oil. It circulates through the oil system on the truck and if you do regular oil changes then youll be fine on the HPOP. As far as the dip stick/oil pan problem, You can do it your self but 8 chances out of 10 youll have to pull the engine and if you take it to the dealer, get ready for one hell of a bill

Dont waste your time changing the res. oil. Its pointless.

With the dipstick youll have to pull the engine to take the pan off if the nut is loose.

I don't want to restart an old fight, but I disagree about not changing your HPOP oil. This is a very expensive motor. I also have several antique vehicles that have motors that would be difficult to replace. The HPOP system holds 3 quarts. The lower system 15 more. Those of you who leave the old oil up top are basically doing the same thing as if you were to start to drain the oil on your gasser, and then shove the plug back in with a quart of dirty oil left in the pan. Maybe I'm obsessive, but when I change my oil, I leave the plug out until the last drop is out. I know you can't get every drop out of the top, but by sucking out the old oil (which is always thicker and dirtier than what comes out of the pan - proof positive it doesn't circulate well) and putting fresh in for three cycles, you've at least diluted the top end oil the best you can without draining the rails. Then I change the bottom end oil.

I can run my truck for 4000 miles before my oil on the stick even starts looking black. My friends who swear the top end oil change is unnecessary can't even get out of the driveway without black oil.

To get the plug out, put your allen wrench in the plug and thwack it good with your hammer to free the threads - it usually comes out good after that.

We need to have some of the guys with 400,000+ miles come in and say whether or not they have ever changed the HPOP oil...

I had 250k on my 95 and it had never been changed and no problems at all.

my oil dont turn blk for a good while after a oil change about 3-3500 miles and i never have changed the hpop oil. Its not worth it.

Its not worth it. Feel free to do it with the oil in the res the first time, but once you crank that motor, that oil in the heads has to move through 15 qt of new oil before it gets pulled back into the HPOP. Kinda like changing clean oil isn't it?

I've got guys that come in the clinic that say they've smoked for 40 years and never got lung cancer. That doesn't make it smart.

My question to anyone capable of scientific thought is this - if the oil really mixes as well as everyone seems to think - why wouldn't it have exactly the same consistency as the oil in the pan. It DOESN'T. You can pull it out and compare it side by side. The oil in the reservoir always is thick as gear oil and twice as black.
