Oil Canister Install

[Keith]

Could some describe how to properly install the oil canister and filter on my 67 small block so it doesn't leak. I have a new reproduction canister, filter, and gasket. I will also be installing the oil bypass valve that sits above the filter. I wont be starting the engine for another 7-10 months. Should I use any type of gasket sealant between the block and oil bypass and how about on the thin rubber gasket of the oil filter. Thanks as always Keith

Re: Oil Canister Install

My experience has alway been that the canister never leaks except for one time when the gasket was not properly seated and it leaked big time. The one sure fire way to install the gasket correctly is to remove the by-pass valve assembly, but it should be noted that there is a gasket (5573980) between this and the cylinder case which should be renewed. The lack of a gasket here will cause a slight internal leak which will allow a small (probably tiny) quantity of unfiltered oil to seep into the entrance to the main gallery. The oil filter housing gasket may be good for up to half a dozen R and Is before it gives up, but I used to change it every other filter change. When installing it, use a little white lithium grease to hold it in position while reinstalling the by pass valve assembly and cannister.

To add to what Duke has said, the only times I've had a cannister leak is when I had forgotten to remove the old ring gasket, and installed a new gasket over the old one. Many times, you'll find several crunched up there. That's a recipe for a leak. An old dental pick is a great tool for digging out old gaskets and reminants of gaskets. If you use just one, you should be fine. Chuck

To the excellent advice already posted I can add:

I use an awl to dig out (sometimes an appropriate term) the old gasket ring. Coat with a bit of lithium grease to hold the new one in place in the block while you spin the cannister up. If it will leak (and you only have to have this happen once!) it will leave an immediate, impressive oil slick on your driveway (not as impressive, however, as that if one backs out of the garage....over the oil collection pan...).

Haven't heard anything intrinsic to the reproductions predispoing to leakage. I've also become somewhat leery about overtightening the mounting bolt..I use 12 ft-lbs and haven't experienced any leaks. Remember to align (per NCRS specs) so the silkscreen is facing outwards.

Re: Get 'em from my dental hygenist ...every time!

I NEVER leave the dentist's office without at least two "picks" - after all these years, they're used to it, and save the questionable ones for me. I have 20-25 of them, and they're terrific quality tools for working on carburetors and instruments. Ask for them - otherwise they just throw them away.

Was the fellow who aligned the silk screen "per NCRS specs" the same guy who put the NCRS decal on top of the frame rail for judging credit?

At one time I designed dental handpieces for American Hospital Supply Corp's Midwest American division, your dentist may be considering raising your bill if he reads your post John, these implements are not exactly cheap, won't break the bank but...

Joe,

Although I've never purchased one, I've often seen these for sale at car shows on the "tool tables".

Re: Oil Canister Install

You are quite correct, they are often available at the swap meets and car shows on the tool tables. I have purchased some - they are quite useful and quite inexpensive ($2-$3) by the time they hit the swap meets.
