Oil Filter Problem - Blowing Out Seal

OT - This problem is not on JD equipment, but it is an interesting one, and others may have run into it!

The oil filter seal is being blown out by oil pressure when operating in our extremely cold weather. The seal O.D. is slightly larger than the oil filter adaptor and the machined face on the oil filter adaptor appears to slope away to the outer edge. 10W30 is being used - as recommended. There is no oil pressure gauge, one will be added.

Anyone else seen this happen?

Had that happen to me years ago on a car I had. The old thing used a lot of oil so I tried one of those snake oil things that said it would slow oil burning down and stop oil leaks. What happened is it stopped up the relief valve in the oil pump so the oil pressure got to high and the seal in the oil filter was the weak link in the oil system. Cost me big time to get it fixed
 
Like OLD, I had an auto back in the late 70's that would do this any time I used certain brand filters and slso if I didn't tighten it just right!

MFG recommended a filter placement torque of 18 FT LBS & by golly they meant it too! That engine had a small "bead" on the flange & if tightened too tight, the bead would cut the seal and it would leak. Don't tighten it enough and would blow out looking EXACTLY like the one in the picture.

Ran that car for 250 thousand miles & never had a problem when I used the torque wrench.

MAYBE there is a specific torque recommended by the MFG?
 
I agree with deer tails.
Stick a gauge in where that sender is so you know what the pressure is. Might need adjusting.
 
The problem I had was not the wrong type or brand of filter it was the stuck oil pump relief valve
 
So, what, exactly is it on.... there MAY be alternate filters available for that engine that have a smaller seal ring OD.
 
There has to be a groove for the seal to fit into.
Just a flat seal between two surfaces won't work,it would squeeze out when tightened up.
 
The engine is a Briggs V-twin # 303447-0447-01 used on a Cub Cadet 2160 with a large front-mounted sno-blower. I am looking into alternate filters with the correct specs and a smaller OD seal.
My local NAPA store has a special reference document that lists filters by specs rather than by part number. We will also add an oil pressure gauge to find out what's happening. Our winter has been EXTREMELY cold so the oil pressure may be much higher than normal.
 
Interesting about a specific torque.
I usually just tighten them real tight our I follow what's written on the body of the new filter.

I'm concerned about the pressure relief valve, but the parts list doesn't show a separate item. It may be built into the pump body or the filter adapter assembly
 
Most oil pressure relief valves in those pumps are built into the pump body it self. The pump should have a nut/cap looking thing on it some place and that should be the relief valve if like most oil pumps I have messed with
 
What brand & # filter?, then it could be compared to an oem dimension. Looks to big . China made also, so 'may fit'.The thread size is very common, lots of filters will spin on, doesn't mean it'll work.
Baldwin B7165, Napa 7035, B&S 842921-short, Baldwin BT223, B&S 491056-long are a place to start.
 
Yep, thought it looked Briggs-ish!

Hopefully you can find another filter OK for the application with a smaller "O" ring OD.

I went through the same deal with a filterhead on a Massey tractor a few years back, and an alternate (smaller "O" ring OD) filter has solved the problem.
 
Forgot-looking @ pic, the o-ring should be (probably) in where the flat part is, between the recess and taper, you can see a shinier ring in the pic.
 
This one was a German built '79 VW Diesel. Filters came with warning notes in the box telling how some VW engines could produce very high oil pressures and installation torque was critical. It listed a specific oil pressure which I no longer remember. I put a full gauge set in it with an oil pressure gauge that went to 120 PSI. On cold starts it pegged that gauge EVERY time, winter & summer no matter the grade of oil! Kinda used that as my "take it easy gauge". I didn't drive it hard until the gauge started to leave that right hand peg.
 
CJinMI,

I've discussed this a few times with my friend, the owner.
He insists that the sealing face is flat, but it sure looks from the picture that it is tapered from the center to the outside. He says thats where the gasket makes contact and that's why it looks different???
He doesn't have a shop or garage so he's working on this in minus 30 degree weather!!!!!!!!
 
Those old VW diesels where good engines just a bit of the different side of thing.
 
Could well be just the pic, wouldn't make sense to machine it with an angle. The first pic tho' I think the o-ring (square section) is out to far, it should'nt be right on the edge, there is nothing to support it.
 
Pretty obvious that's not the right filter.
Find one that the ring is enclosed on both sides
making it impossible to slide out.
Or you might remove the ring from a new filter
and use weatherstrip adhesive to glue it to the filter and after curing, oil the ring before installing.
