K&N oil filter

[hvac]

Ready to Pull the trigger and order a K&N oil filter for the 5.5 onan q.v., 2017 model. Like the 1 inch nut built on the filter.

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

Comments from those who have used these filters?

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.

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,

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.

Or actual events by people that I've corresponded with. K&N oil filters with the nut on the top are thoroughly vilified by people who have had them fail and dump oil directly in front of their rear wheel. Talk about something that will get your attention in a hurry. Either the filter starts to leak around the nut, or the O-ring is improperly placed to seal the filter, and that results in the oil getting dumped on the ground. Not hype, not internet folklore, real results from real people.

Obviously a registered distributor of K&N products will be totally unbiased. Riiiight.Obviously a registered distributor of K&N products will be totally unbiased. Riiiight.

I've used K&N air filters on my bikes for over 30 years, but I wouldn't put a K&N oil filter on anything I cared about.

Wrong. Just because I sell them don't mean I endorse their usage, why I put in the comment about the filters and the MAF sensor.

Now, that you've laid the groundwork for your claim... Care to provide a link and I mean not a heresay link but an actual substantiating link?

In all actuality, the spot welded on nut is font for tightening the filter, it's there for removal only. ANY AND ALL OIL FILTERS SHOULD ONLY BE HAND TIGHTENED OR, 1/2 TURN PAST THE POINT AT WHICH THE GASKET CONTACTS THE FILTER FLANGE No exceptions.

If you used the nut to tighten an oil filter (and deform the gasket or 'O' ring in the process, you are the nut doing it, not the spot welded nut on the end of the case....

So, having said that, pleas provide a substantiating link or cease commenting about things you have little knowledge about other than Internet 'knowledge'.

[hvac]

Wow. I've used their air filters for decades. Thinking was nut would make removal easier.

I agree and I'm a registered distributor of K&N products. Having said that, I use what I sell on everything including my pressure lubed lawnmower...

The only thing that may be of a concern with a K&N oiled type air filter is over oiling it may cause a MAF sensor issue on a gas motor because the oil vaporizes in the intake stream and fouls the MAF sensor. Other than that, never had an issue with any filter.

I think the negative comments about K&N are internet folklore perpetuated by stupidity.
