Full Flow Oil Filter Swelling Up

As Steve said, the IN is on the outside of the filter and the OUT comes from the center. Your picture doesn't show me well enough where the ports actually lead to.

some oil filters have a built in bypass. If they flow the wrong way the bypass doesn't work. That means the filter would see the full pressure from the pump when cold. It would probably balloon then rupture the diaphragm.

example:

Okay, maybe it was just optical delusion, but it appeared that the In port on that adapter made a right-angle turn to the center boss. One would have to view the underside to be sure, of course.

As far as the bypass valve goes, that is simply there to pass oil around the filter media if the media gets clogged up enough to impair flow. Yes, it would allow excessive pressure to build up if the filter was clogged badly and the flow in the filter was backwards ( ie. center to outside), but there should be no such danger if the filter was new and clean.

As anoying as it is the oil light quit often does flicker at idle. This may have nothing to do with the oil pressure and have everything to do with the oil sender switch.
Put a gauge on it and see what your pressure is at idle and for every 1K rpm.

Good luck

You posted the pic of the oil adapter is not yours. Please post a picture of yours?

The issue is that anti drainback valve, it's a one way valve and really restricts the flow, hopefully the bearings haven't suffered from starvation yet.
The casting on that filter mount doesn't always let you know what's going on underneath, you have to look from below to see where the passages actually go.

The OP said he had 80 psi at a cold idle. Assuming he's reading from the standard oil pressure port, that means he's seeing pressure downstrem of the remote filter.

Gentlemen,

The adapter shown in the picture I posted is not my filter adapter; it's just a picture I took from google images to show what kind of adapter i'm dealing with. Mine is has the inlet and outlet going the opposite direction and it does not have the threaded hole on top of the inlet port. You can see my actual adapter in the picture below.

You wont have any of these problems if you take the fool-flow filter off, use good air cleaners and change oil every 2000 miles
