    I run a Wix 51794 tall 1 1/2 quart filter with a blocked bypass, filtered oil, no issues, no brainer.

    I would think knowing the intended use is important.

    Is it pleasure or race only, the motor it's for and the intended oil filter would be helpful.

    I use the non by pass adapter on my BBC. I did a lot of reading. The filter I use has a bypass in it
    ( Baldwin). Why would you not want to change out your bypass each time you change the filter? Going the other way means you have no way of knowing what is going on with the bypass as it is part of the block. I guess you could run both but then you wouldn't know if the block mount was working properly and just bypassing all the time.

    There was a discussion about oil filters a while back that seemed to cover a lot territory.

    At the time, the Wix filter received a lot of positive reviews along with some others.
    That's when I switched to the 51061 WIX. Apparently WIX makes the filters for NAPA, but NAPA calls theirs 1061, but it's still the same filter.

    The WIX 51794 appears to be a larger filter with the same specifications.

    Something to note, is that both the 51061 and 51794 can be purchased with an "R" at the end of their numbering. That is their RACING filter and it is different.

    Others may disagree, but for most uses, the one without the "R" is the preferred choice usually.
    The 51061 and 51794 have a filtration of 21 microns, while the "R" (Racing) has a 60 micron filtration.

    It's my understanding that if you change oil after each racing event, the "R" could be preferred sometimes, otherwise the Non "R" is preferred.

    With the R racing version of the Wix filters you are gaining flow at the cost of allowing particles that are THREE times as large to flow through your lubrication system. The standard tall version is more than capable of fulfilling flow demands while providing superior filtration.

    You make a good point about the flow of the larger filter.
    I don't know if it makes much difference, but it looks like the larger filter may add a bit of additional cooling for the oil. That may be a stretch, but it's a thought.

    The only downside to the larger filter is the requirement of more oil and its longer length.
    I don't have a lot of clearance in my flat now for removing the filter, but it looks like there is enough to remove and replace the longer filter.
    I'd just have to be more careful not spill more oil.
    They do cost a little more too.

    NAPA does have that filter with their number.
    The WIX and NAPA filter is the same, with the NAPA using the same number as WIX without the #5 at the beginning of the number.

    Compare prices for both.

    With all due respect....
    WTF do you guys think you are accomplishing with no bypass... either in filter or adapter?
    Don't wanna run a stock adapter... ok, I get that. I'm with you...
    BUT..... what kind of shit is in your oil that you MUST filter it no matter what?
    AND what happens when you 50wt guys fire your shit up cold as hell, no preheat in the oil... and rev the hell out of it?
    Wags

    You SHOULD be able to run with no filter at all (meaning oil not filtered) and not have any issues.
    Just my opinion.

    Finally, a breathe of reason. I am impressed. This is a concern for those of us that use a Dan Olson oil cooler. It eliminates the bypass. Not good. Need to use a filter WITH a bypass. If your oil has bad stuff in it, you have bigger problems.
    I don't know what I don't know because I forgot !!!

    First off I do not HAVE to run full filtration, I CHOOSE to.

    I run 10-30 full synthetic, by the time I park, then idle out my oil is heated sufficiently for cruising RPM

    Having the choice between fully filtered oil with no down side, versus partially bypassed oil allowing potentially harmful particles to recirculate through the system, I fail to see any benefit of bypassed oil.

    I've been using blocked bypasses and the tall Wix/Napa filter on my engines for 30+ years with no problem, why change now? And just for kicks I have rare earth magnets on the bottom of my pan and wrapped around my tall oil filter.
