Does anyone know how Bob accomplished his testing on the Escort by using no filter? Did he rig up a custom made fitting on the oil filter mount or what?

If I recall correctly, he used a permacool block adapter with the hose just running from outlet to inlet. Not glamorous, but effective.

He used a Ford Escort! I doubt it was to improve oil flow...I am thinking he did this to send in a sample for UOA and see what the results showed compared to running a filter. I could be wrong that's why I was wondering about the result?

I believe he did a no filter UOA vs. a filtered UOA ..he may have also done a Frantz type bypass filter with no full flow, but that may have been from Ralph with his MotorGuard. I could be blending the two.
The results weren't too much different with and w/o the filter.

As I recall, the results were better without the filter! I remember all the hoopla about it. Bob had concluded that spin in full flow filters are essentially useless and simply create resistance to oil flow. They might be useful during engine break in to catch the pterodactyl sized particles, but the very fine wear metals will pass right through.
Well, guess that would show that air filtration is by far the most important filter( sand particle that is). My own test of two 12,000 mile OCIs with one no filter change and another changing it halfway showed no change in UOA results. I agree with Bob, like the appendix oil filters are pretty much a useless appendage on todays modern engines and oils.
I somewhat disagree.
Even with primative media available at the time, Ford did tests with full flow filters and the addition of a full flow (instead of the bypass set up they had been using) supposedly cut wear in half.
I'm not saying there is a lot of junk in the oil past break-in (with a good air filter and reasonable OCI) but the filters people cut open seem to have a fair amount of junk on them that I don't want circulationg freely.

I agree with r_r ... besides, in a UOA I doubt it measures the big stuff that typically gets trapped in an oil filter - like carbon blow-by, sludge, larger metal particles/shavings from wear, etc. Most of the stuff that goes through an oil filter is the stuff that is seen in a UOA.

This is why I always say that a full flow filter should be biased for flow and not filtration! If one wants to filter the snot out of the oil they make bypass filters that only take about 10% of the total flow and slowly filter it to sub micron levels.
This is also why I have always insisted that good air filtration is far more important and with air filtration paper is the best thing going. I amnot drag racing my Camry 1/4 at a time and Ia mnot running the Paris to Dakar Rally in it either. What little hypothetical power gain I might gain from somethign like a K&N is meaniless in the application and manner of usage I drive! So on a daily drive I am preety adamint that cold air kits and non-paper filters are for sucker and meant to make someone money while doing next to nothing or worse damaging the engine slowly by letting in too much dirt!
I thought Bob abd who ever helped him run the test drilled the internal part of the adapater and blocked off the in and out holes for reliability. Hose's are another leak path if not needed.
Experiments used to be a huge part of this site and many of us had various things going on at any given time.
I recall Bob also having some good experiments showing that Lucas fuel additive worked and left almost no deposits behind when it burnt and he also had one that showed how bad Lucas oil additive was etc..... Personely I think all these test should have their own section and should be stickied and locked so youc an read them and wath the video's but not add to them.
