Oil Filter Adapter - Bypass

Post by Tio Pancho »

Ok so in the process of a rebuild. Motor is a stock 360. In the process of going through the oil filter adapter The little rubber plug/valve for the bypass went missing. 😡😡
What are my options? Is this little piece available?
Is the oil filter adapter available?

Looking around on the interwebs I see that I can buy the oil filter adapter. I also saw a remote filter adapter that caught my eye. Does anyone have experience with these? Quality?
Thanks in advance.

I installed a remote filter kit on my '73 304 CJ-5 in 1974. It was a Jeep Corp kit that used parts from a RHD Matador, available through the dealership parts department. Unlikely you can find the same thing today, but it worked fine. Put the filter right up on top, and made oil changes easy.

That valve is in the parts book, Jeep PN 3173202. Maybe you can find it by that number. I recall there was an post on IFSJA that showed how to replace that bypass with a solid plate. Was claimed to have some advantage? I'll see if I can find it.

OK. So I read the post on the elimination of the bypass. Seems simple enough. What I am thinking about is the reasons to keep or delete.
Keeping it would keep the engine alive in an emergency oil situation where the filter is plugged. But would put unfiltered oil through the system. However, I wonder if I would notice that this is what is happening enough to then deal with it without letting it continue for too long,

Deleting the bypass would cause a more urgent situation of oil pressure loss and possible damage, but would signal an issue that needs to be dealt with.

What does the peanut gallery think?

Quality oil filters now have an internal bypass. I use Purolator L30005. I think it has a 22psi bypass. Not on the shelf anymore unless you're lucky. Still available, just have to order them.

Thanks Rammit. I thought I remembered reading about internal bypasses on some filters. That being said it would make the remote filter idea even more appealing.

Is a bypass there to continue a flow of oil if the filter is totally plugged, or is it there to prevent seal blowout on cold weather / high RPM operation? I'd think if your oil filter is totally plugged up you have bigger problems and your motor is toast anyway...
