Don't know nothin bout this stuff but wouldn't just a really really strong spring keep the valve closed

Many don't want to use our spin on oil filter adapter, so we have in production now a billet housing that will incorporate a higher pressure bypass valve as well as a really big magnet located at the bypass. We have a similar version already available for models where a spin on oil filter adapter was not practical:

These are going through the machine shop now. It's something we started on last year but we have just been too busy to get some of these new products pushed through.






If there is enough demand, we can make a version that omits the bypass completely.

I’m very interested!!!!!!

I literally just ordered the URO off RockAuto, so unless they come back to me with an "oops, sorry", I think they have stock now.

Hi 996love, our engineers checked several pieces from our inventory, and were able to thread the covers into an OEM housing by hand. Did you happen to lubricate the threads and o-ring with some fresh engine oil? Metal-on-metal threads will have more drag than plastic-on-metal, but some lubricant helps offset the friction difference. Please contact us, thanks!

There is no new aluminum version on the page link . What is the cost, is it available now, etc? Uro makes one that includes a filter. What is your offering?
Interested. Curious.

YMMV

Uhhh, my URO 99610702055PRM aluminum filter canister DID NOT come with a filter.
The plastic Porsche oem filter housing from Pelican DOES come with a filter in the housing.

Guys, I am slow on the uptake for this one. Why would someone want to run this on their engine? Just trying to figure out the application/purpose. Its a cool canister.

Thanks for an explanation.

Well, guess they owe me a filter, cause they surely didn't include one in my URO 99610702055PRM order.

Well, this is a very nice, seems to be high quality, thick/solid/strong housing, that can possibly be drilled and tapped for oil temp/pressure/accusump(?), fittings. And the bypass port easily 'bypassed'.

GC996

Fair enough. Another mundane question. What is the reason/application for bypassing the bypass port?

allcool

When running heavy weight oils some say on cold starts its possible for the high pressure filter bypass to open up(especially if the filter is clogged ) and discharge all the crap on the bottom of filter housing directly in to the main oil gallery, going directly to main bearings. Not good.

But more than likely with the frequency we change our oil/filter at, the filter will never get clogged enough to trigger a 'clogged, in bypass' problem (unless the imsb or something else disintegrates completely filling the filter, very unlikely but possible). But suppose heavy weigh oil might trigger a bypass under the right circumstances, and any debris in bottom of filter will flow directly into bearings...

Some are concerned that the aluminum canister will burst from high pressure, more than likely never ever happen, probably the plastic canister won't either, unless its been damaged, maybe by a backyard mechanic's channel locks/filter wrench.
Also the oil pressure relief valve will also open and bypass high pressure back to sump on that side of the circuit.

So, bottom line, many of use will take our chances with no filter canister bypass, thus keeping all the debris//crap/smegma/etc, in the filter, never to leave the filter. Its lots Less of a risk than crap being sent to bearings when in filter bypass, Just like the LN spin on filter adapters don't have a bypass. And those spin on (beer/soup can thick) filters are far less robust/thick than this URO aluminum one, or even the oem plastic one, and with no bypass.

Most of the people that don't like the filter bypass have seen trashed main bearings from debris scoring when tearing down bum engines....

Thanks @allcool . Very good info. You have me thinking.
