oil filter restriction orifice
Prior to 1st time install of oil filter system & after cleaning, i checked the inlet orifice restriction fitting & it measured .070". Think I've read it s/b 1/16", .063"? Am I OK @ .007" over @ .070"?

Re: oil filter restriction orifice
I wouldn't think it would make that much difference.

Re: oil filter restriction orifice
Hard to believe that .007 would make much of a difference. Piece of notebook writing paper is .005 ". I would use it.

While you are checking things out check for the two oil return holes in the center tube.

Re: oil filter restriction orifice
I’ll go w it. thought it’d be fine but always best to check. I knew from previous threads too big on that diameter would effect oil pressure in the engine.
I’ll check for being clear & size of oil return tube holes as well. Thx for the help!

Re: oil filter restriction orifice
If you thick a restrictor in the filter line will prevent circulation, just leave the filter body cap loose. Don't ask how I know that!

Re: oil filter restriction orifice
Not sure what ur saying? I wasn’t concerned about restrictor would stop flow, my only concern was if restrictor hole was too large it would reduce oil pressure to engine. Leaving filter body cap loose sounds messy?

Re: oil filter restriction orifice
Guys, the factory spec for that restrictor fitting was .058 - .063.
Now to me, if it were .070", I'd solder it up and bring it back within spec. Yeah, it may not make a difference but then again, it just may. For a the minimum effort to do it correct - well, why not do it correct? If .070" was good enough, I'd think Ford would have opened up the spec. The wider the spec, the cheaper to produce.

Re: oil filter restriction orifice
A .060" orifice has 75% of the area of a .070" orifice. So the larger one will flow 25% more than the .060" will. Does it matter? Maybe not,but I'm with Kube here...

So long as the restrictor does not exceed the flow capabilities of the two .063 dia. return holes there are not any issues. The larger restrictor hole may in fact be an advantage because it will flow more oil in a given time frame.

Re: oil filter restriction orifice
I'm running a remote filter housing and ford spin on. I have installed a .062 restrictor fitting in the RETURN line fitting to the engine. this is so there will unrestricted flow to the filter housing with no chance of it becoming plugged. Clean oil can not close the restrictor. The longer the oil is in the can it will have a chance to cool and better filtering. Something that works for me. Oil pressure is good, no issues there. Your thoughts?

Re: oil filter restriction orifice
That's what I'm doing as well. Makes sense to me...just have to make sure the gasket (if using the OEM can) is in good order since the can will have full oil pressure with the orifice in the return side. I'm also using an aftermarket filter base and a spin-on bypass filter (Baldwin B50) so the filter can gasket is not an issue.

Re: oil filter restriction orifice
Just in case there may be someone needing a restrictor fitting, I obtained one with a 0.065 orifice from a turbo supply company on eBay. It was less than $10 including shipping.

Re: oil filter restriction orifice
easy solution its a bypass filter so plug the fitting at the block start engine and take a reading then install with the restriction in place and take readings again if its the same your fine and the system will handle it any significant drop in pressure check the install or you need to have a good look at your lube system

Re: oil filter restriction orifice
Don't follow this at all, with a bypass filter the canister is always full of oil up to the level of the return holes, which are high up in the canister. Also, how would a restrictor in the return line have any impact on the oil flow to the oil galley. And lastly, I am unaware of any .060 restrictor being designed into a bypass filter system. The .060 restrictor is on the inlet side of the canister and there are two .060 holes in the return pipe inside the canister. Adding an additional .060 restrictor in the return line would defeat the whole idea of doubling the flow out of the canister.
