4wd 90° engine oil filter adapter mod

[Will L.]

Ok, anyone with a 4wd knows these leak. You loosen the filter and the adapter turns a hair. You tighten the bolt and the oring still leaks. Buy the kit for a few bucks- it’s cheap enough. But doing it every 10,000 miles is annoying!!!

Please someone tell me they have already figured out a mod to end this waste of time. Feel free to name it after yourself so the whole 6.5 world knows you are a hero.

Also someone tell us the engineer’s address that didn’t make a locating pin, second bolt, tab& slot to stop this in the beginning so we can send him oily Christmas cards every year. Haha.

PS. No, I have never tried just The Right Stuff instead of oring... that was my first thought but seems like it will fail also because nothing to stop the rotation.

Will such a easy fix and yet if it’s not done, it’s anoying as hell.
Over the years I spent 150 bucks on paper towels cleaning the driveway and underside of the hummer.
I should of known that 8 bucks and 30 min will fix the problem for at least 20 000 miles.

And then O Rings dry out and time to replace again.
No problem at all.

Mine leaks too. I have a Leroy reseal kit ready to go at next oil change, but something to prevent it leaking again would be amazeballs.

 

[Will L.]

Yeah, I am just tired of doing it. I would love to install my engine this time and never touch the orings again.
I did install a remote filter kit on my last 6.5 pickup and it didn’t leak again but i might have only ran it 40,000 miles afterwards. Definitely not more than 2 years before I sold it so idk if it was a forever fix. Fitting a remote filter on a hummer is harder also- so little room compared to a truck.

My thought was changing the filter caused the adapter to pivot and leak.

Along with the used oil filter in the filter box would make it a nice gift.

I went with a remote filter. AMSOIL's dual bypass. In the ~35K miles that I had the truck with the remote filter, zero problems and filter changes were EASY!

Only issue I had to address with the install was that it needed additional hose in order to mount where I wanted the remote base.

One of my Hummers has remote oil filter kit,
That’s the one I don’t have oil leak issue, but they remote filter system created another problem,
How to open and change the filter without dumping oil all over,
maybe on the pick up trucks it will be easier to have that done, but on the hummer there is no way to catch that left over oil coming out of the filter.

I suspect it's the aluminum part on cast iron always moving differently with heat cycles. IMO The rotation is just a symptom of failed orings. (Mine leaked just fine without moving. What torque?! The bolt won't turn anymore. )

Then there is extreme oil temps that go past what the rubber o-rings and notably stiff old oil cooler hoses are rated for.

I recall the 1993 is a different center bolt design than 1995.

 

[Hummer H1]

I think is combination of both, heat destroys the O rings and vibration makes it perfect situation for hot thin oil to seep through,

40lb of torque on the bolt.

I had my remote setup mounted so that the filters were horizontal which guaranteed that oil would spill when the filter was un-screwed. I just planned for it and was rare when any oil hit the pavement instead of staying in the catch pan. At first I pre-drained the filters by way of a punched hole, but stopped that practice as it tended to make for more clean-up to get oil off of the filter wrench.

My eldest boychild just bought a brand new 2019 Ram diesel truck. He also got this oil filter plug so when the filter is dropped down a way, the plug can be screwed onto the filter then filter removed without dumping oil all over the frame and wheel. I dont see how that would help us GM guys with the four wheel drive adapter though. LOL
I rebuilt My step-sons 94 or so S10 4X4 pickup. it had a remote oil filter system that placed the oil filters onto the bottom of the front radiator support, there is a hatch that can be opened on the skid plate to gain access to the filters. I thought that was a pretty slick setup.

And here all this time I thought it was my fault for doing a bad install on the Leroy kit!
