Re: {Chrysler 300} 300C can-type oil filter

Something a bit telling in the statement, "I've owned the car for 46 years.", someone else owned it from 1957, making the total 68 years. There is such a thing as metal fatigue, eventually.

How many times has that can been taken off and put back on?

I got my first G in the 80's when it was a cool 25 year old car just barely able to qualify for antique plates and insurance. Even my 'newest' antique (Hurst) is now a 55 year old relic.

I have to keep reminding myself to check pieces of my cars that are now over half a century old that I would never have thought of checking 'back in the day'.

I don't believe any of our vehicles were designed to still be roaming the streets today.

YMMV.

you can attempt to deform back the other way ( anvil and shaped receptir like a large socket ) or? have probably better have a machine shop make a delrin washer to take up excess free play under stock washer . Maybe .1” .
trying to reshape by habd runs the risk of tilting the flat seal face etc . Your call .
I’d put the hot heads adapter ( angled
up one) get much a better 2025 screw on filter , newer tech no leaks easy to change
Mopar filter from dealer is very good as is Bosch . Some of others are junk

I have the original can-type oil filter on my 300C (see attached). I changed the oil and installed a new filter recently. The can leaked. I pulled the can twice and re-installed with a new gasket each time but it continues to leak. I can’t get it to leak, engine running, in the shop. It only leaks when I take the car out on the road. Is there a trick to installing the oil filter can without leaking? The can never leaked previously, the whole time I have owned the car (46 years).
