PSA - cartridge filter oil change

I have a new to me TO-30 and it has the cartridge or canister style oil filter. I'm so used to the self contained ones, I almost made a mistake.

Once I got the old filter out, I was ready to slam my new Baldwin P-73 in there, new o-ring, new crush washer and call it good. Then, I stuck my finger in the bottom edge well of the canister, and it came out with about 2 oz of cruddy, semi-solid goo. I got a piece of cardboard, and tore off a strip to go in and scoop it out, and I got another 2-3oz of more goopy goo.

After more scraping, and some carb cleaner, and rags I got all the crud off the inner walls, and the pickup tube in center. If you have a cartridge filter type, and do an oil change by all means, clean that canister out, because five 'll get you ten it hasn't been done for 20 years.

Now all the liars can come on and tell me how they do that religiously every oil change. ya-huh.

Probably hasn't been changed in at
least 20 years. I flush the inside
and outside of the cannister with
brake cleaner when changing the
filter. Never seen any goop in the
housing though. Still using 30wt
non detergent oil too.

I have never cleaned mine. I look inside each time and see perfectly clean inside wall and put the new filter in. Ya-huh.

Did you dig out the old gasket?

If there is that much sludge inside the oil filter housing, you might want to check how much sludge is in the rest of the engine too. Look down the oil fill tube, drop the pan, or pull the valve cover or engine side covers if it has them to check for varnish and sludge.

An engine oil flush with a high amount of solvents and detergents might loosen much of the sludge without tearing the engine apart to scrape it all out. Follow the directions on the flush container. Removing the sludge around old hardened seals might bring some new oil leaks.

I'm not going to say I wipe it out each oil change though I do look in and clean it out with solvent even if I don't see anything. I also wipe out the sump the filter sets on. As for the o-ring gasket in the bottom the canister sets on IF they didn't leak I don't change them.Some are on there for many years. No point changing something that is not bad. I do poke them with the screwdriver to see if they got hard if not put er together

What kind of oil have you been using?

I have the pan off the engine. There's no sludge in the lower gallery, but I haven't had the valve cover off. If there was sludge, it might be up there.

I'll be using SAE 40, I'm in a hot state, and will mostly use it summer. Wondering now about the oil pump gears. If I'm going to repl those, now is the time while I have it apart.

I can't see where you posted what oil you are using in your OP.

I have a p73 cart. Filter on my CASE DC. Yes have to clean out canister. Mine has a little clean out
port that can open to rinse out crud. Filter was a bit hard to find, but Oreilys can order it. They
have a vintage tractor division from where I have gotten numerous parts. Ask them.

The super c had a groove like that. Now it has one of those
spin on kits on top of it so it should pack completely full of goo
and not get looked at for 30 years or at least till that flat o ring
in the kit leaks...I have my doubts as to weather it will stay put
it spins on the same way as the filter.

my oil filter canister has a drain port on it. i have inferred from the lack of sludge on old filters that it's not a problem, but i'll definitely make a point of taking a closer look next time i change it. having just looked at the dipstick, tho, that definitely won't be happening this year. that stuff looked like i put it in yesterday

he said the tractor was 'new to me.' i took that to mean he hasn't used any oil in it yet

Yes I knew that. I was responding to Doc's response to Russ.
