Not to get off the original subject of "excessive blow-by",....
BUT,......sorry to disagree with you "Spike" but I just don't
agree with you about that issue!! I have run the "high flow"
filters in my 96' Dodge CTD since day one (eight years). In the
early stages, I heard the arguments about "high flow vs paper
filter elements" so I decided to have my oil analyzed to see
if there would be a difference. You know what??? I saw almost
no difference between the two on my truck!!! All areas with
the "high flow" filters were always within the "normal" range.
After awhile, I just quit doing the analysis because of that!!
As I said in my earlier post, my engine is being rebuilt now.
It did not "quit" but began to have the "blow-by" Mark had
mentioned and it was using some oil. But,.....as I said we
attribute that to the high EGT's I was continually putting on
the engine while drag racing or towing heavy. The actual
"wear" as measured by the machine shop was so slight
that the block will not even have to be bored!!

Oil analysis when looking at dust ingestion will as a rule only show some increase in iron (Fe), chromium (Cr), and silicon (Si) if there is dust being ingested. It usually is not a major jump unless you are operating in a dusty environment.
But, hey, What do I know? I am just a filter service engineer trying to provide sound maintenance information. You guys on these forums are for the most part hobby truckers, not working trucks.

Seems to me that if high flow airfilters killed engines that a lot of manufacturers would be out of business. Not the case.
Over 300k on K&Ns used in a dusty agricultural environment for me.

Sorry to "ruffle your feathers" there "Spike!" Honestly, that
was not my intention and if it came across that way to you,
my apologies!
Since 1992, when I purchased my first Dodge CTD, I have
heard the "high flow vs. paper filter element" filter debate
over and over again!! There are two sides to this debate
and as I said, my personal experience and testing (through
oil analysis) just did not show that the wear was worse
with the "high flow elements!" I see your point on the
certain elements going up (silicon, iron, and chromium)
with dust ingestion, but my results were showing almost
identical numbers Sir.
As far as your statement; "You guys on these forms
are for the most part hobby truckers, not working trucks."
"Spike" I know many members of this and the other
diesel forms that work their trucks very hard on a daily
basis using them for construction use, hotshot delivery,
agricultural & marine service duty. And some of them
are in real dusty conditions you describe. As DTR Member
"infidel" posted, "300K on K&N's used in a dusty
agricultural environment for him."
The good thing about this website is the opportunity
for us all to discuss and "debate" the issues on these
diesel trucks!! Every member will ultimately make up
their own minds about whether they want a high-flow
filter or the paper element filter.

Not so. How many people smoke? How many Subarus are out there? If a product is advertised heavily enough and hyped enough there will be lots of buyers. It doesn't matter if the product is bad for you or if it is the worst of its kind, advertising works and word-of-mouth to the contrary will be ignored. There is always something to say about any product that will convince people to buy it, sometimes only that it's "sexy". You don't expect a manufacturer to point out the faults in their products, do you?

Which brand of oil are you using? I used a popular brand that advertises as "pure base oil" and I ended up using a quart every 1500 miles while I never used to add oil between changes at all. This was after two years (8 changes) of this popular oil brand. I went to a less expensive WalMart oil in 5 gal pail and the consumption went to 1 quart every 2500 miles in the first change. Four changes later it is back to 5000 miles to a quart.
The only explanation I can come up with is that the rings were gummed up and not fitting the bore with proper tension. The higher detergency action of the WalMart oil seemed to clean deposits up. I also know that a thermostat running "too cool" can produce the same symptoms, so check that temperature.
