Oil filter adapter leaks (seeps)

[jmiller]

I'm having problems keeping the oil filter adapter from leaking. I'm ready to replace the 3rd set of orings in 3 years.

Both the large housing oring and the bolt oring are leaking. It leaks just enough to be irritating and leave small spots all over the driveway.

Looking for idea's.

I think its might be related to the oil pressure. At cold start, the oil pressure gauge is pegged, @ +80psi. At cruising speed, oil pressure is usually around 60psi.


I was considering cleaning everything up and adding RTV to the large oring and in the outer bolt oring groves. The other option is to find thicker orings to add more sealing area.

I gave up on mine and just lived with the seeps. It never leaked enough to spray back, but was always wet.

 

[ak diesel driver]

what if you surfaced the mating areas so as to make the orings fit tighter

 

[tanman_2006]

x2 i wonder if the adapters warp?

How are you getting such high pressure? Did you put an HO oil squirt pump on a nonsquirt 6.2?

 

[jmiller]

Reman motor, I think its a HO pump.

I thought about surfacing the flange, but any leak from the bolt would need a thicker oring.

Suppose I need to locate exactly where the leak is, its been awhile since its been checked.

I had to remove my adapter when I put on my home built oil cooler lines, I put a little red permatex gasket maker on along with the old O rings, it seals fine.

Well, with my soft cast on, I crawled under the truck yesterday.

Pulled the oil filter adapter and cleaned every thing up. Installed new orings and a thin coat of ultra black on the rim & large oring along with the outer bolt oring and a bead around the bolt head.

Went to the car wash to clean off the crap under the truck and ran some errands.

Crawled back under and the front universal is wet! Damm @#$!@&*

The adapter is fine, the oil cooler block fittings are seeping. I applied liquid teflon when I installed them, last year. They are so tight that I can't get another turn on them. I guess I should have used RTV on the threads.


Now I have to pull the exhaust manifold, filter adapter, oil cooler lines . . . . . . . . .

I have better luck with tape than the liquid.

X2 on tape.
Maybe you have an out of spec/sloppy adaptor machine tolerence? Maybe get a new one and see.

I've always used tape and dope. The owner of the local hardware store told me to do that 35 years ago and it's been working for me ever since.

Do you have a Lubrication Specialist or pmdcable oil line kit?

I've never had to pull the exhaust manifold to get to the fittings. I do use a 90 degree open end. I forget which size. 3/4 or 7/8 maybe. Possibly metric

What is the latest and greatest in the engine oil cooler line world?

I may need a kit for the 1994 K3500? Who's kits come with the oil filter adapter o rings?

Has anybody been able to address the way the lines in the kits bend up to attach to the cooler? I've never really cared for the way that end of my projects have turned out. They always seemed a little bindy.

I also need a T put in one of the lines to supply my FS2500 bypass oil filter

I put new o rings on mine when i rebuilt the engine, it started seeping within a year. Seeps enough to get a drip or so off every once in a while. I see it as rust protection.

 

[restoguy]

This is pissing me off too. I put new orings in when I did my rebuild and used dope on the cooler lines. Well the lines leaked like everyone else who used dope! So I pulled it all apart and used tape, then the adaptor started leaking from the big oring!(it was probably always leaking, but you couldn't tell because the oil lines were so bad) I'm thinking I might try to find a bigger cross section oring in the same diameter to get more 'squish'.

When using dope be sure to let it set over night. Tape will desolve over time and leak too. Permatex makes a good pipe dope. Its blue and sets up hard as a rock. Only issue is if you ever need to remove the fitting.
