I searched for a while and all i got was positive stuff on the scotts oil filter. I guess the only thing i didnt find was how hard are they to clean and something about there should only be one o-ring or gasket, not one on the front?

I use the same one from my 426's on my 450 - they are easy to clean with gas/contact cleaner/brake cleaner or anything. My Scotts filter has a rubber gasket on the opening side on the filter - goes towards the engine - I do have to reglue it every 3mos as heat will dissolve the glue that holds the seal on. It is not a o-ring it is a gasket seal and there are cheaper alternatives to Scotts stainless filters out there -you can do a search - I am extremely happy with the Scotts - had the same one for 4 years - :cry:

The Scotts filter is very nice. It holds up well and is very easy to clean. I just wash in hot water with simple green along with my air filters. Then everything gets a good rinse and dry. I usually clean mine every 3rd oil change.

The Scott's uses only the seal on the outer end of the filter.

They are easily cleaned, and there are a number of approaches you can use.

The important things to remember are that the inside is the "clean" side, that is, the oil flows from the outside in, so keep all the dirty oil, solvent, whatever, out of it and on the outside only.

You can use soap and water, or something like an air filter cleaner and water. Finish rinsing by running water in through the outer end and out through the filter mesh, then dry it with air.

I use clean mineral spirits to rinse the filter off, then run some through the filter with compressed air so it's aerated (new, clean stuff only). Spray Carb Cleaners also work well. Then I follow that by squeezing Automatic Transmission fluid through it with a small plastic bottle. Over the years, I learned that ATF has a remarkable ability to lift and carry off fine debris I didn't know was there. Rinse that away with a little clean motor oil and it's ready.

Using the Scott's, I can have a clean filter with every oil change for a cost of 15 minutes total time spent.

Be careful they do come apart over time....

Absolutely true

Scott's are much tougher. The bad part is that the bronze filters can easily be damaged enough to double the particle size they will pass, or worse, without your being able to see it.

The point is that you really have no idea whether the bronze screen is damaged or not, at least not at a micronic level. The bronze element filters only down to about 70 microns to begin with, as opposed to 35 microns for the Scotts. The element is delicate enough that "holes" can be unwittingly created in the mesh as large as 200-400 microns (.000024, or 24 millionths of an inch), or more, which of course, you cannot see.

Also, the bronze filters are glued rather than welded together.

If a rebuild will cost me $1000, I don't mind spending $65 to put it off for a while. It's cheap insurance.
