Default Oil Filter Change Question

About to do my first oil filter change on a Lycoming IO-360 and searching the Internet I'm a bit confused on whether to lubricate the filter gasket prior to installing and torquing or not.

From my checking on-line:

Lycoming documentation says do it, Tempest says no, Champion doesn't directly answer the question.

What do folks commonly do?

Thanks for any info!

I always dip my finger in oil (clean or dirty, doesn't matter) and apply a light film to the flat part of the seal.

Tempest has a new filter called EZSpin that doesn’t require lube like its old version did. For all others, as far as I know, a light film of DC-4 is appropriate or oil if DC-4 is not handy. Good luck.

Default Don't over-tighten

Follow the directions on the new filter for proper torque....it is easy to over-tighten which can make the filter very difficult to remove.

Default Now it makes sense!

OK, now I get it. I didn't catch that the current filter is a Tempest "EZ-Spin" which says on the exterior to not use lubrication.

I'm going with a new Champion so I'll follow the Lycoming procedure.

I did pick up a torque wrench from ACS but seems like most postings I've seen indicate a 3/4 turn from initial seating ends up about right.

Thanks for the info!

I have always used 3/4 turn, never had an issue.

Are you aware of the screen in the sump?

Nope, haven't got any info on that, is it something readily accessible, how often does need cleaning?

Thanks for the heads up! I did find the thread on here that explains the situation...not quite clear on what size crush washer the IO-360 will need but for sure will get the screen checked & cleaned on the next oil change.

Easy way to properly torque is to use a 1" box wrench being pulled at 90 degree angle with a fish scale. The moment arm is a bit under a foot, so I pull until I see about 18 lbs. I haven't noted how much the rotation is from first contact.

You'll need a 1" crush washer (AN900-16). I clean the screen with every oil change. If you have a tail dragger be prepared to catch about a pint of oil when you remove the screen.
