Technical Noob 283 oil filter adapter question plus a new one

The 283 I’m building had a bypass missing the bypass part of it. Pulled a bypass and spin on adapter off another 283
The bypass didn’t have a gasket between the block and bypass.

Looked up a bypass on the internets and it shows a gasket

not seeing this on other breakdowns I looked up.
So is a gasket used here. Another 283 I have didn’t have one either. There isn’t one in the gasket kit.
Question #2.
the gasket between the bypass and adapter


haven’t located one online. Just the adapters.
Measure and guess the thickness or just junk all this and get a new set up.

 

no gasket between valve and block. The gasket was used with truck engines with an oil cooler, I think.

The adapters usually have a felt or rubber gasket to seal against the valve. Do you have an adapter yet? If not, just buy one, it should be complete.

although I've gone back to canisters on mine, because I'm an idiot. Have one on the 396 in my truck, and the 327 in my Corvette. I like piddling with the old fashioned stuff.

 

Non of mine still have the canister.
One had the adapter
The seal crumbled when removed

 

You also need the large diameter rubber square O ring that goes around the bypass valve, that the adapter seals to the block with. It comes with the canister filter.

The inner seal between the adapter and valve is usually a felt washer, perhaps 1/16" thick.

 

What year did Chevrolet switch to a spin on oil filter?

 

A year to year check on an Impala with a 327 says for small blocks 68 when they went to big journal.
62 194 Chevy II sixes came with a spin on as did later and larger sixes.
That adapter has to be used with a bypass valve. If you don't use one you will distort and crack the adapter plus it won't filter any oil.

 

I like the canister oil filter in some applications. Having two canister lengths to choose from and an almost puncture proof filter had some merit. In some ways it's too bad the blocks machine work changed to eliminate that option. I have some original factory filter bypass adapters and the kit does contain a gasket for the block side. And as mentioned, the bypass adapter must be inplace under the spin on adapter to support the spin on adapter and provide the bypass.

 

Just put a 283 together - no gasket on the original bypass, but the "reclaimed" adapter I used did have a seal that went against the area you have circled - of course is also used the "original" style outer seal (that the canister sealed against) too - IIRC there was another adapter available back in the day that did not use the original bypass - it replaced everything and used a ford! FL-1A filter....

 

On the gasket...sometimes parts are included that aren't needed, or used originally. For example, Chevy engine gasket sets have included exhaust manifold gaskets for decades, even though Chevy never used them.

I doubt that it would hurt to install the gasket between the block and bypass valve, even if it's not needed. So do whatever you feel comfy.

 

Looking for a canister.

probably just put it back like it was.

biggest question was if a gasket was used between the bypass and block
The 2 I took apart yesterday didn’t have one. The internets pic shows one listed for a corvette

 

They didn't use them when they built the engines. But since there's a gasket that fits, for another application, someone decided that they should include the gasket.

 

If any one is looking a canister i have some, 2 different lengths. Don

 

1964 Nova 283.

 

Both EZ to locate filters?
I’d prefer the shorter canister. Kinda congested in that area on the car

 

I think they're all kind of long...this is measured from the bottom of the block. There might be a longer filter that was used on trucks? I haven't seen it, but wouldn't surprise me.

 

I usually save the square o ring gasket that is in every spin on filter . I found one that fits the spin on adapter . I just installed it on a 65 283 .

 

Oh...finding filters...not like the old days when you could find AC PF-141 at every parts store. I order batches of 4 Wix 51143 filters from rockauto, like I do for all our cars.

Autozone has an STP filter in stock, but Oreillys doesn't stock one, where I live

 

The longer one is a truck filter canister for the most part. The shorter one is a 1 quart and the long one is a 2 quart.
I ran into that back in high school Auto shop in the mid 60's when we did a lot of oil changes in the shop and a couple of regular customers had 1-1/2 ton Chevy V8 trucks.

 

I was thinking the trucks were the longer ones.
I’ve got a c60 pats truck. It has the long one. Kinda dont want to use that

 

You guys just made me go to The Rock and look and see what a SBC canister filter looks like.

 

this is what they used to look like. I got them at pep boys.

 

Local parts store used to keep em for my 235. I think tractors used em as well

 

I’ve changed quite a few canister filters on old Farmalls, but have never seen one for a Chevrolet.

 

just not old enough....

 

I thought you were an inline 6 guy anyway Mr. Myrick. Why waste time with those 2 extra holes in the block!?

 

Well, I’m am oddball but I really didn’t want a straight 6 in my 51 merc

I just rescue those old poor 6s.

 

I bet you’d still drive it!

 

Here are the two canisters that you usually find. The tall truck and the shorter car. It's possible with so many unique applications you could stumble into something different. The truck canister is 7 1/2" tall and the car 6 1/2".

 

Thanks. Hunting one locally.
Got friends searching in their junk piles

 

I see them at swap meet, many people change to the spin on.

I have a truck canister type on my late 261 (full flow) and a couple in reserve one for the race car and one for an undetermined future project.
