G80 3.8 Oil Filter - Bypass?

[TinsleyC]

I use the WIX WL10033 oil filter on my car and in another thread, and in other threads and forums, people have warned about not using OEM oil filters. Since the WIX is a top rated filter, I wonder why.

Spin on oil filters have a bypass valve that allows for continued oil flow if they get clogged. This protects the engine from burning up if the filter cannot pass oil.

My 3.8 uses a cartridge filter and it's a simple design - I don't think they have a valve and bypass option. At least I can't see one.

So, is the bypass function built into the filter housing on the car, or does the filter have one? Or is it more complicated than that? I certainly want to retain the bypass feature.

Don’t know for sure but my hunch is there is a spring loaded pressure valve in the filter mount that will open at a certain differential pressure if the filter pressure from inlet to outlet exceeds a predetermined amount. From a design standpoint would be easy enough to incorporate to ensure engine never is without oil. If Genesis had a conventional FSM hard copy we could easily see the oil flow diagram and if a bypass valve exist or not? The online version is cost prohibitive to use for a research project.

I agree that the oil filter design seems simple without any anti- drain back function or bypass. Just an filter element located in a oil cooler/container. The only issue with an aftermarket filter would be the quality of filter used which could collapse or has poor filtration.

Aftermarket canister filters(spin-on) can be problematic due to poor anti-drain back valves which would allow some engines to start dry and add additional wear to the engine over time compared to stock oil filters. The cartridge system in our engines does not have that problem. Any flow resistance would most likely be bypassed in the oil cooler section that attaches to the block while also holding enough oil for startups.
