Default Oil Filter Housing Gasket Sealant?

Hi Folks,

I ordered this new OEM oil filter housing gasket and was wondering if anyone would suggest sealing it (thinly) with some Permatex black before installation. Repair manual seems to indicate it should go in dry. Surfaces on the housing and block are both clean and polished smooth.



Thanks!

It should just go on dry. If it makes you feel better to use sealant you can.

I just put mine on dry. There's an o-ring in there too, make sure you replace it at the same time.

Once the gasket absorbs oil, the sealant won't stick to it anymore. Probably wind up getting sealant in your oil passages. I'd say don't do it.

Thanks for the great advice everyone - Dry it is!

SBJ - I didn't see an o-ring when I pulled the housing - and don't see one shown in the shop manual. Could I have missed it? The engine is a KA24E.

Thanks!

It's on the inside of the housing, on the same fluid passage the oil filter threads onto.


Here's a picture of my block when I had it all torn down. If you look closely at where the oil filter housing bolts on you can see a lip where the o-ring goes. If you didn't see it taking it off it's probably still inside the oil filter housing. I'll see if I can find you a part number for it.

EDIT: Found it. It's part# 21311-V0700. YEPEE if you are reading this thread please feel free to chime or correct me.

If you use Permatex BROWN...nothing gets through that, not oil, not gas, not NOTHIN'...

I would use a thin coat (really thin) of the brown. It never leaks. The only drawback is that you WILL work a bit trying to get it off, should you have to remove that part later. Rather than the going for the tube version of this Brown, get the bottle with the brush. Easier to control, easier to make thin coat. Wear rubber gloves you will be scraping that stuff off your fingers for days. The tube stuff does work better on the larger jobs, like doing an oil pan.

On a side note, I never use silicone sealer on anything. As far as leaks go...I absolutely will not put up with them. Not a drip, not a whisper...nowhere and NO HOW.
