Cracked oil filter canister

[Nickw]

hey everyone I crack my Oil Filter Canister a little do you think it will have a affect to the oil if it’s a little cracked? Or would
I have to get a new one?

Hi Nick,

In the perfect world, you are going to want to replace it.

However, as a stop-gap measure, you may be able to seal up the crack with epoxy or JB-Weld. You are going to need to thoroughly degrease and clean the area so that the material will stick.
There's a product called Hy-Poxy H-450 Alumabond epoxy made specifically for such things. It's worth a try.
I think cleanliness will be the key in making this work.

That canister is scrap now and not easily repairable. Looks like someone installed two O-rings in there which will make them crack every time.

Replace it as soon as you can.

Or spend a few bucks for a 190SL group Spin-on Oil Filter Adapter.  I love mine, and no o-rings or center bolt to leak like a sieve during oil changes.  Quick and easy and a lot cleaner.

However, it's not original and would probably lose you a few points in a concours d'elegance.

My favorite vintage car phrase applies, I'm a purist, but not a masochist.

As a stop-gap until you decide to replace it  I would use a large diameter hose clip, Jubilee type, as this will also hold the fractured piece in place.
Suggest putting the clip on the canister first and then offering up to the engine .

Good luck.

Can you tell what it’s made of?  Maybe a welder/machine shop can do a repair.

[Benz Dr.]

It's die cast aluminum and it's not worth trying to fix. The spin on filter is less than half the size of the cartridge filter and seems small for an engine with 6 liters of oil.

I have a spare casting if you need one. You will need to get seals for it.

My engine rebuilder advised me that it is important that the housing has a good lower seal as it is almost impossible to change it.
He actually gave my a housing back with the statement that it is "junk"

[Cees Klumper]

Dirk - I recall replacing the lower seal at least once, it is do-able. As I recall, I had to remove a sort of 'hat' at the bottom with a pick, then I could swap the seal, then press the 'hat' back on. That's my recollection anyway, probably around 15 years ago I did this.

[dirkbalter]

Cees, I have no done or attempted to do it. Metric gave me a new one and did not want to deal with that.
Let me change my statement from "almost impossible" to "tricky". lol.

The bottom seal is replaceable. The metal retainer ring is pressed on and can be removed. The metal retainer ring is missing on the filter in your picture. Buy the canister from Dan. Maybe he will install the new seals for you?

[Benz Dr.]

The hat part is available as a separate part. The trick is to use a new one because they don't seem to be reusable.

Hi,
the bottom seal can be replaced easily by pushing the metal retainer ring from outside of the canister because there is a tiny rim where you can put a screwdriver in place.

It would be better to replace it. Here is a link to a new one. In case you damage the "hat" when removing or replacing it they also sell it but I could not locate it. Give George a call.

Hey Dan, the early 911's use a spin on filter and they use 9 litres of oil.  You know the old saying, "Its not how big it is, it's how you use it." 

[Nickw]

Do not want to argue with that, but my 1971 914-6 with a 1974 2.7 flat six has a 16 quart oil capacity.

I know how, I just can't remember why.
