Can someone tell me what type of oil filtration system, if any, was installed on the 65 mustang. Bypass system or full flow system?

 

I don't know what your asking. There should be an oil filter on the lower front driverside corner of the engine.

 

from what I know there's only "full flow + bypass" or "full flow without bypass".
mustangs are typical full flow, no added bypass

 

Every Ford since 1957 has used a full flow with bypass, disposable filter system.

I'm also curious why you are posing such a question.

 

Well i'm learning about classic cars now as I wish to get one later on. I was reading about how the bypass system was invented in the 40's i believe and the full flow system was invented about 20 years later. So I was just curious as to which system the mustang had.

I understood that a bypass system only drained about 10% of the oil on a cycle so as not to reduce oil pressure.

A full flow system allows all the oil to be filtered on a cycle, but was problematice because if it got clogged then the oil would stop flowing.

I guess the mustang uses a hybrid of the two?

 

Oh, I know what your talking about now. The oil filter has a bypass valve inside it.

 

Yes, I get it now too. The earlier systems merely pulled some of the oil and filtered it. The modern full flow system draws oil from the pan, filters it and then delivers it to the bearings. SO, all oil delivered to the bearings is filtered first.

As tx65 pointed out, the modern oil filter has a bypass valve that allows oil to still flow to the bearings even if some neglectful soul fails to change the oil filter for 20,000 miles such that the filter plugs up.

I think that the fact that a full flow oil system has a BYPASS valve in the filter is what is confusing you.

Hope this helps.

 

Great, thanks that really clears it up for me.
