Oiling the filter gasket

[GH85Carrera]

Yea, for my El Camino, the filter points straight down on the bottom of the engine. I prefill the filter some with oil, and I wet the rubber gasket with some oil. Turn it 3/4 of a tun more from where the rubber ring first touched the engine.

The 911 as we all know has the filter at a 90 degree angle, and it is a dry sump system, so no prefill. Just cleaning up the oil mess from taking the old oil off is enough oil in that area.

Sometimes it's best to not ask "Why"............when your great-grandfather did it, grampa did it, my Dad did it, and I continue to do it today.......

This is the rationale I have been given for oiling the gasket.

I out oil on the gasket because my father taught me to. That would have been about 1964.

If I may ask a related question.....who was the Italian engineer that designed the Ferrari's with side by side filters installed upside down?

Baldwins.... ^^^


I use Baldwin on everything that I care about. Tractors. Light towers. Generators. Diesel trucks (even use the Baldwin fuel filters). I buy them buy the case.

I’ve always been told that it is for ease of removal.. but it does make sense for tightening reasons also.. I know that if you don’t do it, it will do exactly like that picture above!
