Thread: 327 SBC oil problem

Tweet

I`m currently rebuilding a 327 SBC and there is something wrong with the oil flow at the filter adaptor the center oring does not contact the engine block.Is this normal? What forces the oil into the filter if the two sides have no seperation. It seem that the oil would take the shortest route and go into the system with out being filterd?Any and all help welcome thanks for your reply. Tracy

Being a 327, I have to ask....What type of filter are you using...The canister (pre 68) or the screw on (68-69)??

To put a screw on type on a pre 68, you need a special adapter.

I`m currently have an AC Delco adaptor for the spin on filter. The center oring does not contact the block.

What center O ring. There is only one seal on the chevy filter its on the OD and threaded on the ID???

Do you mean a spin on adapter from a later model engine....or a special adapter to convert the canister type to the spin on type?

The later model adapter from a factory block wont work....There is nowhere for the seal of the spin on filter to seal on the block. You need to use an aftermarket adapter.

Just trying to get straight what you are using.

Also, if I remember correctly, some of the aftermarket ones were junk too............Maybe, another one of us old guys will remember.........I am having one of those "Old timer" moments about this.........

There are two seals, one on the outer diam. and one that looks like it should contact the oil hole in the center but when installed it is about 1/2 inch from the center oil hole. I`ve also tried to install a Mr. gasket adapter as well and it is the same as the AC Delco adapter. Will this adapter be acceptiable to use? or am I going to need the canistor type filter. Just a note the engine was makeing noise and the main and rod bearings all indicated oil starvation.

A picture would tell a lot..........Is that possible?

I`ll take some pic today. Thanks

I hope this works? I have one pic of the block and one of the adapter.Thanks for the help.

I see what you are saying....Its been years since I put one of these on, but I think there is a part missing from that adapter. Looks like it needs a rubber sleeve that fits in that centre groove.
Remember what I said before...there were good and bad adapters made.

Thanks for all the help. I orderd the adapter from summit . It should be here today. I`ll let you know how it works. I also went to 4 machine shops and they all looked at me like I had two heads. Again thanks for all the help. Tracy

Iput a cheapo one from autozone on my 63 327 motor without any problems did forget how it all went together though. ED
