Gaskets---a question or two.

Patrick HMD · Posted: Tue Oct 09, 2012 12:24 am Post subject: Gaskets---a question or two.

I need to make up a gasket where the oil filter cannister bolts up to the motor block on an 'M'. What would I be looking for in an auto parts store? How thick? I have some Karropak that mics out at .022 thick. Not sure if that is good enough.

I would think 1/16" rubberized sheet gasket would work just fine. Good clean surface and some permitex. not sure what Karropak is must be brand name. I make most of my own gaskets. saves time and money. oldiron29

.022 is plenty thick enough for gsk material,... but what is karropak?

I guess It's a trade name, because it's got the little trademark sign next to it. Also FEL-PRO in front of it. That's probably the maker. Feels and looks like thick brown paper. Bought it at Autozone.
I bought an oil pan gasket from Steiners, and it's .050 thick, and feels more pliable. I was thinking about using some of that if I can find some material. If it works with oil pans it should be ok for the cannister, right?

Thanks guys.

It may sound weird, but I've always used the cardboard from cereal boxes and I've never had a leak. Of course, I'm not making head gaskets either. :-)

Is the cannister a casting? If so the .022 should be ok. If it"s a stamping I"d want something thicker.

BTW I"ve also had good luck with cardboard gaskets. I"ve also used paper for thin gaskets such as for oil pumps. I always coat such field-expedient gaskets with a thin coat of silicone and let it dry.

When I first started making my own gaskets, I bought some material in 1/16". 1/32" and 1/64" thicknesses. I quickly found out that 1/16" is much too thick for most applications. 1/32" is just right in most cases and 1/64" occasionally.

nope, dont need that thick.as i said .020 is plenty but even .010 is plenty good. a a gasket has to seal up to .010 warpage. and sure is not that in those small pieces. oil pan is thin and warped so need thicker gasket.and its cork!

That's what I do too. Been doing it for years. newspaper makes thin gaskets. I do buy cork material for radiator gaskets.
