At the shop, the Chrysler spin-on for the 4.7 motors has a very shallow depth for the O-ring to sit in. When installing under the splash pan, that filter can be bumped off the can fairly easily, leading to another Valdez moment.

When ever I see the spin on conversion, there is usually a laundry list of improvements to go along with it.

When I was 20 I worked for a short time in the lube rack at a Chevy dealer (about 1971) and there were still a lot of cars that had canister filters. A whole lot of times I had to unbolt the aluminum insert to get at and pry out old hardened 'O' rings sometimes 3 deep.

I removed the oil filter adapter that was on my stock '61 283 for NCRS. Now I want to go back to using a regular spin-on filter.

In the collective wisdom here what's the best product to buy?

These will get it done for you:



IIRC, a similar conversion kit, branded Mr Gasket, is available from Summit, etc.

I agree they both do the same **** however I hate changing oil with canister filters.
My 66 hasnt had the canister on it for at least 25 years.
On my Toyota Tundra, for ease of filter access I cut a hole in the skid plate and then converted it to a spin on. Clean, quick and easy

So I went to do my Spring oil change on my ‘61 and as I was warming the engine I noticed a significant oil leak under the car. After investigating, I found that the oil was coming from around the filter. I changed the oil before winter and have not run the car since, so I don’t have a concern about damage but, I’m puzzled about the leak.

A previous owner had added a spin-on adapter and the oil filter I put on last year was snug but not super tight. I went ahead with the oil change and used the hex head stamped into the K&N filter to tighten the new filter a bit more than normal. I started the car and checked for leaks and all was good.

So my question is about whether anyone has experience with a spin-on adapter (or its gasket) failing. Never had this problem before and I will be checking closely for leaks this season. Just wondering whether I should replace the spin-on adapter. It’s been on the car for at least 45 years.

Depending on which element you use, I notice that some don't fit quite as good over the sealing surface. That's why I am still running the cartridge because I don't trust the width of the adapter sealing surface to be a good match to the element's seal.

Thanks. If by “element” you are referring to the spin-on filter, I have used several brands with no problem before. I have been using K&N for the last few years with no leaks until now. I always wipe off the gasket seat and pre-lubricate the gasket on the filter. I inspected the filter I removed and that gasket looked fine.

I’m inclined to think that I am the problem and that I just didn’t tighten the filter enough. Never had that happen before. Just keeping an eye on it for now. If I see new leaks, I will take a harder look at the adapter.

2KREDVert

Yes, element is the spin on filter. I don't just check for leaks, I inspect the mating of the element lip seal to the adapter sealing surface and look for 100% contact. Most I have tried don't fully contact. May not leak but could blow out down the road.

leaston78

Thanks. Next time I have the filter off, I’ll take some measurements.

2KREDVert

No need to measure. You can see the contact surface as you tighten the filter against it. I also lapped the contact surface of the adapter on a large piece of glass and sandpaper to make sure it was flat. It wasn't even close when I started.

leaston78

Thanks. If I decide to replace it, I will do the lapping on the new adapter. On my ‘61, the filter is tucked up pretty tight between the exhaust and the oil pan but I can probably see it with a mirror. Thanks for the tip. I was thinking measurements would help me select the best fit when I buy a new filter.

Both of my cars have canister filters and I am probably going to switch to the above filter simply for the added capacity.

2KREDVert

Looks like that filter has seen better days!

I have met Tom in person and you can take it to the bank that there is NOTHING wrong with that filter regardless of some of the paint being scraped off. He is meticulous in the maintenance of his cars.
