Maybe you are over torquing the filter.
agree, in my opinion I don't believe you should introduce foreign matl's to the lube system.

When installing an oil filter in an automobile, I always tightened them until they made contact plus 1/4 turn. I never had one leak, and they were always easy to remove - even though I had used motor oil on the gasket. Now these spin-on Tempest filters on my plane specify 17 ft.lbs of torque, which seems WAY to tight to me but that's what I have been doing. When I asked the A&P at my local maintenance shop why my filter was difficult to remove, he told me "The oil gets hot and sticks. That won't happen if you use DC-4". We'll see...

In the meantime, I bought myself an AntiSplatAero filter wrench from Aircraft Spruce. That should help.

That makes a lot of sense, but in doing a little Internet research, Lycoming (and many others) recommends using DC-4 on the filter gaskets. I found that information in Lycoming SSP-885-1 which is their 1988 instruction for replacing an old screen-type filter with a spin-on filter. They also say, "Always use a six point socket when installing the filter". I used a crow-foot, which worked fine when installing but not removing. Live and learn...

I use DC-4, never had a problem, torquing to the manufacturer's specs ...

Using DC-4 is per instructions on the outside of the Champion filters...

Default hmmmmm intersting

the ACS data sheet link for DC-4

https://www.aircraftspruce.ca/catalog/pdf/09-27700.pdf

interesting reading.
ok to use with a and b, but not c.

for something designed as a dielectric sealant, curious that Lyc would spec it as a gasket lube....go figure.

Been chasing high CHT's. Internal engine timing, timing, fuel flow, baffling of all sorts with little appreciable changes. I've been looking at the EZ cool. They state 25% cooler on the video. That would get me in the 380 range, and I would be so happy after all of the other fixes.
Does anyone have any numbers?
