K&N oil filter

I've never seen a filter fight before. I guess we've run out of things to rage against.

I just installed a K&N on the little Italian diesel. Seems like mileage has gone up. Local, no towing. Was 24, now 27.

Problem with anything but a genuine Onan OIL filter is the length.
These aftermarket short filters will spin on and work, but...

All aftermarket filters for the Onan I've seen/used is the length is to short to hang below and 'seal' the serrated rubber shield/gasket that keeps in the cooling airflow for the genny/engine. And keeps out road debris/dirt.
For those that haven't seen this extra gasket on the Onan chassis oil filter opening, its not the gasket in the base of the oil filter.Its another gasket that semi-seals the top of the oil filter canister.And it needs the filter long enough to hang down thru this seal/gasket.

This added length of a genuine Onan oil filter also makes it easy to grab the filter and spin it off/on no problem. No filter 'nut' is needed if you use the Onan filter. Tighten by hand is all I ever use on my filters(on any motor). Never have leaks or problems, ever. Feel it out, feel when the filter seats and the thick rubber gasket(or o-ring) starts too compress, then just another 1/4 to 1/2 turn will 'feel' tight and fully seated. Do not over torque a filter with a filter wrench. Filter wrenches are for taking off stubborn filters.



Never torque down an oil filter, always only hand tighten nice and 'snug'after cleaning the mating surface on block and oiling the gasket well. And use your eyes when cleaning off the blocks oil filter mating surface. Make sure the old gasket is not still stuck to engine, 2 gaskets is not ideal and a major cause of oil filter leaks...

I'm a firm believer in filling the filters full of oil before installing it to avoid cumulative extra wear from a dry start every oil change.

Couple of questions. Is the number HP 8029 correct for replacement of onan 122086?

Comments from those who have used these filters?

I had a ton of problems on my truck after using one. I think the oil coats some of the engine's inlet sensors and knocked my MPG down.

I think you're talking about the air filter and he is talking about the oil filter. There are problems if you overoil the air filters, as was mentioned before. After examining the air filter on my Cummins I went to a BHAF, Big Honkin' Air Filter, as the creases of the K&N seemed to trap a lot of gook even though it was cleaned pretty frequently. I think the diesels just process too much air.

Good thing you're done because that way you won't have to eat those words of yours. Specifically these:

"Honda has no specified torque value for tightening an oil filter and I ought to know, I deal with bikes everyday."

The Honda Service Manual for my '99 Honda VFR specifically states: "Install the new oil filter cartridge and tighten to the specified torque, 10 N-m, 1 kgf-m, 7 lb.-ft."

The Honda Service Manual for my wife's 600cc SilverWing states the same thing with the difference being the torque values, which are 26 N-m, 2.7 kgf-m, 20 lb.-ft.

Makes a person wonder what else you're wrong about. I sure wouldn't want you working on anything of mine.

There are no published torque specs for any oil filter on any engine. Again, you cannot 'torque' anything with a compressable gasket. It's impossible because the gasket compresses as the filter is tightened.

for the last time (because I have other more important things to do than argue...1/2 TURN PAST THE POINT AT WHICH THE GASKET CONTACTS THE FILTER BASE.

Got it?

Have a nice day... I'm done here.

Okay here's one:

K&N Oil Filter Failure

Took a couple seconds on my VFR forum.

Used the nut to tighten the filter, EXACTLY COUNTER TO WHAT I STATED IN MY LAST POST (BEFORE YOURS) Honda has no specified torque value for tightening an oil filter and I ought to know, I deal with bikes everyday. Why no torque value? because the gasket is compressable. You cannot have a prevailing torque value with a compressable gasket. Don't work that way, never has, never will.

1/2 turn past the gasket contacting the filter base.

If you note, the case in the picture is also deformed, probably from cranking on the nut, or should I say the 'nut cranking on the nut.

Still not a viable substantiated link but rather someone's ill fortune by their own hand.

Again the nut putting on the filter, not the filter's fault,

Does it specifically state on the box the filter comes in, not to use the nut to tighten the filter? I can certainly see someone using the nut with a torque wrench to tighten to the factory torque specs.

Okay here's one:

K&N Oil Filter Failure

Took a couple seconds on my VFR forum. Lots of reading there and several posters showing the results of a K&N oil filter failure. So there are issues.

Sorry that you feel you need to denigrate someone with an opposing viewpoint. Just stating the facts. So apology accepted.
