Help....... SBC puking oil from oil filter

I was just priming the oil pump on my freshly rebuilt 327 and saw that no oil was coming out of the pushrods. Then, I noticed that about 6 quarts of oil was pooled on the floor! I spun the priming tool again to see exactly how it was leaking and basically the oil is being pushed out the perimeter of the filter where it meets the block. I used a canton spin on adapter shown in the pic and a wix 51069 filter to replace the canister filter. I'm pretty sure this is a dumb mistake on my part and will be an easy fix, but some guidance would be appreciated. Thanks

If it's a 327 block, you need a different adapter, that will go from cartridge style to spin on style. Or get the complete original cartridge style filter setup, which is the way to go....if you dig old stuff.

 

I did the exact same thing once about 10 years ago, but I can't remember what I did to fix it.

 

an example, there are a few different ones available, some work better than others, some require the original byp*** valve for the cartridge filter still be on the engine

Weird.. The filter spins on just fine with my adapter. I'm not discounting your suggestion by any means, just curious what could cause this problem.

The adapter seals to the block the same way the canister did, then the spin on oil filter seals against the adapter.

 

take a look at the block, see what the hole for the filter looks like. It is different between blocks from the 50s-60s designed for the cartridge filter, and late 60s-up designed for spin on filters.

 

Thanks for the replies so far. Unfortunately, I can't get a look at the block right now. For what it's worth, the block is a '64.
***uming I remove everything from the block, will the adapter that you suggested be the only thing I will need besides the filter?

I'm glad you found it now, instead of when you fired it up.

 

The one I linked to...I think so.

There are a few of them available, I'm not sure which is best.

No kidding! At least It was pretty damned impossible to not notice all the oil on the floor lol. I'm bummed about the 6qts of break in oil lost, but it could have been worse. Thanks all!

Make sure the O ring seal against the block is seating. I saw one that leaked like crazy and when I blew it apart found that the trouble was two O rings had been stacked (one seated against the block with another on top of it.

 

Been there, done that. OIL all over that apartment parking lot. Dang, 30 years ago.

 

Freshly machined block, so I don't think this could be it in my case.

It looks like you simply have the late model spin on filter adapter on an old block, which would explain why it doesn't work. There's no place for the filter gasket to seal to.

 

You're right. I feel a bit dumb, but at least there was no real harm done. Would I need an oil byp*** housing in addition to the adapter?

Even though the thread is the same, the seating area may be a different diameter. I installed one of those adaptors and was told it took a Z9 , when I measured it up against a new filter, they missed by 1/8". I ended up using a completely different filter, and it worked OK.

 

You have to look at the adapter...it should use a byp***, either the original, or have one built into the adapter. The byp*** eliminator thing like you got is ok for race cars, but I would probably not want to use one on a street car.

 

I'm using the Trans-Dapt 1024 on my 327. The first piece is held in with two 1/4 bolts and has a 3/4-16 threaded ****** that you screw in. It is important to check the ****** lenght after you ***emble the parts. I only had about two threads left to hold on the filter. This problem can be fixed with a 3/4-16 X 2 inch bolt. The second part fits the block and has the seat for the filter gasket. It is held on with a cheap-*** nut that I would recomend replacing. The filter you need will be for a Ford, PH-8A or equal.

 

One time the old gasket stuck to the block and I installed a new filter, started the car up, instantly puked all over the driveway...I was of course in a rush and didn't check to see if the old gasket / o ring indeed came off or is damaged

I would bet your problem is with the adapter / o ring...

 

Another thing...the original filter is only a minor nuisance, and is supposed to flow better (spending less time in byp***, which happens a lot with single modern filter) and also has finer filtering.
After the new rig was introduced in the later '60's, Chevy supplied an adaptor for old filter on late block and used that rig on police, taxi, and heavy truck engines...that might well be a hint on what's what.

 

I had to run the same adapter that squirell shows in my327. after a yr it is starting to leak alittle.. I need to remove and check the O ring or see if the adapter has loosened up some.

 

Yeah, it seems like the transdapt adapter is the best option, but the hardware looks a bit flimsy to me. What ford filters can you run? Summit only recommends Fram, which I would like to avoid as I run Wix in all my vehicles.

51515 wix crosses to PH8

 

is there anything wrong with the canister filters?

 

I'm actually kind of on board with going with an original canister. The problem is that I don't have any of the parts. Not sure if I want to scrounge around, I'm itching to fire this ****er up!

I just wound up purchasing an OEM oil byp*** ***embly and a transdapt spin on filter ***embly. This set up seems a bit more solid and rugged. I hope it works out, I will report success or failure to hopefully help the next guy. Thanks for all the advice!

Once happened to me only it was a few days and many miles later -- I noticed the oil pressure suddenly went to zero. Fortunately there was an auto parts store nearby, I walked over and bought oil.
The filter was still fine, it was the extra O ring that blew out.
Now whenever I change the oil and filter I always check that the old O ring comes off when I remove the filter.

 

In this case he was attempting to run a spin on filter directly on a block that came with a canister filter and no spin on can be used on it without an adapter similar to the one Squirrel gave the link to and
Devin purchased.

On a side note I've pulled at least one engine apart that someone had put the spin on adapter on and left out the byp*** valve. That won't work either.

 

It's a good thing it leaked. That is a byp*** eliminator unit In normal use you would be trading unfiltered oil for no oil on startup even 10w is hard to push through filter paper cold.. Some if the NASCAR boys get by warming every thing up good in warm weather.
