Bob,
We went through this about four or five years ago and by trial-and-error pretty-well proved the venturi effect causing erroneous FilterMinder readings.
BTW, why not re-read Guzzle's instructions and see where he got the idea for installing it into the end of the 6637.

Pop, I saw who was involved in the original concept. I do believe it is much better than just disconnecting the filterminder. If it worked at all it is better than nothing. If you got a false warning light its better than no warning light. The location at the end of the filter is the best place to install it, all things considered.
The venturi effect indeed gives a premature warning, and as a result folks may not get the advantage of better-filtered air from a "dirty" filter.
Of course, some prefer to change the media based on appearance, not differential pressure, and who are we......?

Not a bad idea, I just might do that too.

The difference is that the FilterMinder instrument "latches" at it's highest reading, whereas the gauge will read continuous, and you'd have to notice it at its maximum reading to determine actual conditions.

The part that's crazy is that I did a search on here and it seems that I am the only one that this has happened to, and it's happened twice. I really didn't think my filter was that clogged, yea it was pretty dusty but not like that one shown on here a few years ago where they were literally pouring dirt out of the filter, and it still worked. Guess that dust was worse than dirt and it doesn't take much for it to take the path of least resistance, the crank case breather. Air gota come from somewhere.

NO. A standard vacuum guage is 0-30" of MERCURY. Gauges used to check air filter restriction are in inches of WATER. 20" of H20(a fairly dirty airfilter) is about 1.5"hg. That would be very hard to read on a vacuum guage.

I just have a hard time with the idea that you could pull a gallon of oil through the CCV in only 70 miles regardless of how plugged the filter was, especially without some extreme performance issues. I've heard of filters collapsing because they were plugged, but not this kind of oil consumption. I catch maybe a pint of oil in my catch can in 10,000 miles.
I wouldn't be satisfied with this explanation if it were my pickup, I'd keep looking for something else.

or maybe do the CCV mod and see if it stops or see if it starts puking oil out the CCV tube which could mean that the oil is backing up into the valve cover and not draining like it should.

Clux, I do agree with what your saying, but after changing the filter yesterday, not one drop (ok maybe a drop) of oil has disappeared from the dip stick and that’s about 50 miles. I can't explain why so much oil is being sucked from the CCV when the filter clogs up. Scares the hell out of me, and I'm being honest when I say that I never noticed any performance difference when this happened. I'm not seeing any smoke out the hind end either. I don't drive looking out the passenger’s side mirror, but I do use the mirrors, alot.
Wish I had a better explanation, but Joe has nailed my next mod...CCV.

After I installed the 6637 filter and used the filter cover that SpringerPop very generously made for me, those worries were over.
I've installed the AIS filter system and used it for a while, but right now I'm back to using the 6637 filter because it just does such a great job.
Pop, that filter sleeve works great!

HH60FE, you do need to do the CCV.

I have to say that my some of the guys that work at the shop I take my truck to run almost straight used oil during the summer months and unless you are hard on it or sitting at an idle it does not smoke a whole lot more then regular diesel. Also there is not a noticeable difference in power level when you run "free oil" either. I guess I just like my truck too much to try it, either that or the fact that I get fuel for free anyway since I drive it for work.
