Default Dummies Guide to Oil Screen?

I plan on changing my oil and filter tomorrow, and figure that I need to also pull the screen on my O-360. Problem is, I don't where the little guy lives, and I'm not afraid to admit it! I Googled the topic for a few minutes (and searched this site,) but couldn't find what I was looking for. If anyone has a picture and/or some tips (I did read that the screens can be tricky to reinstall properly) please pass them along.

Many thanks!

You will need a crush washer. Check your manual for the correct one. Manual is also a good place to find the location.

Default Ryan....

....it is located just about in the center of the rear of the oil sump, down low...yes, you can't reach it hardly...and it's safetied, usually.

We usually check ours at annual/condition inspection time and usually get bits of carbon from it.

Best,

Oh, oh!. I've checked the screen again just last Saturday, over four hundred hrs now. I don't recall a crush washer under the screen plug. Mine I would say is just a brass type flat washer. It's a Mattituck 360, is this posible that I have a reusable washer?
I also noticed a little carbon in it for the first time.

My guess would be that what you are thinking is a "flat washer" is really a "crushed" crush washer. supostabe a crush washer.

Default OIL SCREEN(S)

If you have an oil filter you have one screen in the sump. This screen is the one with the crush washer and safety wire. If you DON'T have an oil filter, you have a screen located centrally on the accessory housing. This screen housing is held in place by four 1/4" cap screws/and or studs with lock washers. Remove the screws/nuts, pull the housing aft, and the screen will slide out the forward end of the housing. use new lock washers and a new gasket. Install the gasket dry, make sure the gasket and the housing are oriented properly with regard to the oil passage holes. If you have a steam gage for oil temp you COULD have a crush washer on the oil temp probe which screws into the aft end of the housing. More likely you have an electrical connection, or a steam gage probe that does not require a crush washer.

We always check/clean the screen with Oil changes. Apart from anything else, in a taildragger it allows you to drain more oil from the engine.

We also know you are supposed to use a new washer each time... but have yet to get around to getting some So put that under "best practice" but not end of world if you use the old one (worst I can see happening is a slight leak?).
