M20J Oil Change

[The-sky-captain]

I always punch a small hole on top of the filter, then turn the filter so the hole is pointing about towards the ground. Then put something like a water bottle with the top cut off under the hole (thinking this form a funnel would work well here?). Then I use the air compressor in another hole I ouch on what is the top now to blow as much oil out of the old filter as possible.

Yeah, that's a good job for the form a funnel. I also use it to drain the oil overnight from the engine and for catching the oil when checking the suction screen.

I bought one of those form a funnels but ended up not needing it on my most recent change. What I did was drain the oil immediately after flying and then coming back a few days later to remove the filter. Didn't spill a drop.

How many of you actually put a wrench on your filter? Perhaps I'll get flamed for it, but the only time I've ever needed to use a wrench was when one of my partners did the last oil change and over tightened the filter.

Ross,

I always have to use a wrench to take my filter off, and I always tighten it with a wrench as well.

I turn it about 1 to 1.25 times beyond gasket contact and then safety wire it. Never had a leak, never had a problem at removal.

There's a torque value printed on the filter. I use that and safety.

We torque every filter every time. DC4 compound makes them easier to remove. Every filter is opened and examined.

if you tighten it 3/4 turn beyond gasket contact, it is right at 21 FTLB where it should be.

In my plane with the IO-360A3B6D, if I am at the usual 6 quarts and the engine has not been run recently, there is no significant amount of oil in the filter to make a mess.  Personally I like the tradeoff of this versus the vague benefits of draining the oil while the engine is hot.
