Oil bypass, do you block it?

[Rich Biebel]

We buy a very large number of Wix filters every year and nothing looks any different to me quality wise.

Oil, air, fuel and coolant filters.

We have a very large dedicated filter room and stock hundreds.

From small machines to very large, they all get routine service and we use primarily Wix and NAPA if we need something we don’t have.

Wix makes NAPA’s filters

This is what he wrote (It’s better to allow a little trash to circulate inside the engine than to risk a catastrophic failure due to insufficient oil flow.”)

Why would anyone want any trash to circulate through there engine??? What a joke

I have been doing this for 45 years as well and no problems but you have to know what your doing when block a bypass.

Higher burst pressure on the 1061? 285psi vs 270psi on the 1060 per specs, everything else seems the same.

51060 has an anti drain back valve and 51061 does not.

Same filter other than that.

51060 is used for horizontal type mounting....
51061 is for vertical type mounting....

That "valve" is really just a red silicone rubber flap...

You can look at the top and see it covering the holes on any Wix filter that has the anti drain back feature...

Lots of machines mount the filter off the side......and many vehicles.

Without the valve you'll hear a nasty rattle everytime you start your engine for a couple seconds...or a valve that's not working...

I had a 454 pickup that was 4 wheel drive and some various brand filters did not do a good job of retaining oil …and if I heard the rattle I'd replace that filter.....

Wix never had that issue...

Interesting Rich, is it listed in the spec somewhere and I missed it? Had a few stores try to sell me filters w/o the anti drain back for my Buick, always passed figuring it would enhance the mess when I changed it.

What Rich said about the anti-drainback valve is correct. I've used both part numbers interchangeably on my BBC race engines forever.

Thanks for the info
