Anti drain back valve

[Gary Allan]

Oh ..sure. It's all good. by all means use a silicon ADBV is it pleases you and/or it's spec'd for the engine. I do.

Sorry for all the questions in my last post, I should have started a new thread for them.

I guess the noise thing is more talked about because most people will never know if dirty oil is being back-washed into the motor, but you will hear that noise and then it goes away with a filter change and all is good.

Can we agree the ADBV has 2 duties in many applications?

 

[Gary Allan]

Sure ..but let's dwell on the dirty oil thing. It's not the dirty oil that's important. It's the debris being backwashed "en mass". The oil that travels backwards is no more dirty than the stuff that's in the sump. You don't care that it goes to the filter, do you? The original (spl?) kazine filter study seemed to feel that this was very important. "allowing dirty oil to travel back to the sump" ..while leaving out the obvious "which is exactly where it came from ..in exactly the same condition that it was in before it hit the filter". Who cares? Oil from one pass to the next is pretty much identical.

Thanks for the thoughts.

When I said dirty oil I was talking about the oil being dirty from the filter gunk, not the normal dirty oil. I hate typing so I try to cram things in and sometimes that's not the best way.

I am not as experienced with filters as some here I am sure. I have only been changing my own oil since about 1961, and have owned several makes, incuding Peugeot, Studebaker, Nash, Jeep, Renault, VW, Nissan, Toyota, Honda, besides the Big Three of different ages starting with a 50 Mercury coupe with a cartridge filter.

I also don't like arguing for arguing sake and pick a side and stick to it.

I would like to see a reference number to a full flow filter without the ADBV, to look it up on the Wix site and see it. I think they all have it as it is a necessary check valve in all positions. I haven't seen one without is my basis, but that is no proof. Nissan, GM, and some others don't have relief valves in filter but that of course is not the topic. I don't need to be right, just want to see some concrete information, instead of just sentences to the contrary. On screw on bypass filters, it is too long ago to remember. The 56 Nash I had for years had one of those.

I knew what you meant. Keep in mind that you and I are not the only ones reading this. The original filter study was a great thing, but, as with most things, the pioneer can be easily trumped ..since he/she blazed the trail for all that follow.

You'll find on the internet message boards ..you have to qualify everything. Otherwise, you're surely to be nitpicked to death. Many posts need a full disclosure and disclaimer section to close all the doors of critical review. You have to expose your own flaws up front ..for there is a hoard of bazerkers waiting to charge in to assault your position.

Somewhat related pics.

I understand most of the black ADBV are not silicon, can we assume the blue one on the Yamaha is silicon? (Sounds like it from the posters comments)

Is it just me or are these 2 very different looking filters for the same application!

Thanks for the advice Gary, I've bin nitpicked my whole life ... nothing new too me. As long as I'm learning something I win!!! LOL..

You're 100% right, and I am 100% wrong, there are full flows without ADBV. I even have had cars on the app. lists, but it is interesting the B6 comes with or without. I found the Purolator website to be the most helpful, quite a few old cars were without, including 1959 Studebaker Lark V8 which I drove for several years to work in 70's, only comes without. They show pics very clearly. Memory sometimes is not to be relied on, should have researched it more. Interesting.

It's a learning experience here, Newtonville.

I thought that I was wrong 50% of the time ..but I was only half right
