No more K&N…I’m bummed

[PUFF00]

I just switched to LE 8800 oil and when I inspected the turbo boot I saw some dust particles in the boot. So I took off the big cylindrical K&N I had connected directly to the boot and put the stock air box back in. My thought is that I want to go 10,000 miles between oil changes, and I don’t want to chance the K&N letting dust through.

There is definitely a difference in how the truck accelerates. I’ve lost that sudden surge of power I had with the K&N. Now the truck just accelerates smoothly through the RPM range. Before, I would get a sudden surge of power as the turbo spooled up. I miss it. I also miss the sound. It sounded kind of like an air hose venting when I shifted, and I liked hearing the rushing air, or turbo spool-up, when the engine was under load.

I’m bummed.

Dont be bummed, just add the foam sleeve around the 0880 filter and it will filter as good as stock with the flow and noise of the K&N. The part number is 25-0880. It wraps around the filter and eliminates virtually all the dust the Gauuze/mesh filter misses. I dont use that sleeve since all i do is drive on highways that are never very dusty. I have 13k miles on my K&N and i can wipe the inside of my induction boot with a white cloth and it is near spotless

 

[PUFF00]

EMDDIESEL,

I don't have the 0880, I have the E-1796, but it's still a possibility. I may take the bottom part of the stock filter and wrap that around the K&N. Perhaps that is effectively the same as the K&N sleeve.

for 40 bucks try the amsoil ts106 in the stock box

 

[EMDDIESEL]

Using the piece of foam from the stock filter will help, but the foam sleeve the K&N uses is coated in oil also to help trap super fine particles. If you are definatley going to keep the stock airbox, you may as well use the Amsoil. It uses the foam already. Otherwise, yank the stock airbox and put in the RE-0880 K&N and a heat shield from Jannetty or even better, use the Psychotty setup and you will get LOTS of cool clean air to feed your diesel. Awesome sound too

Puff, answer me this one question. Did you have the end of the K&N cone filter stuffed into the original turbo inlet hose, and clamped with the original hose clamp? If so, then you didn't get a good seal, and that is where your dust is coming in from. Get a piece of 4 inch thin wall PVC or exhaust pipe, and insert it into the end of the cone filter, then clamp the turbo hose over the K&N and really tighten it down, but slip some of the silicone on the end first for a better seal. Believe me, this works. The sock is designed for environments that have very fine dust particles, like say the desert here in Phoenix, and I have no dust in my inlet or on the turbo vanes.

Puff, you may also want to try the air filter check that every farmer knows, put a bare light bulb inside the filter and look for any holes. K&N claims that the most common cause of gauze failure is improper cleaning, mainly using high pressure water or compressed air on them. I would stick with the 0880, but you may need a new one.

I second the Amsoil TS106. Ya get the best of
both! Great Big-rig sound and excellent air
filtering. I have about 14,000 miles on mine
and the inside of my air hose and the turbo
are clean as new.

I removed the small snorkle that connects the
airbox to the fender for more air and it also
adds some to the sound! Of course, no ring in
my turbo. I once re-installed it but missed
the turbo spool-up sound and took it back out
for good! #ad

Nevertheless, I will admit to having to trash can a K&N after enthusiastically cleaning it to with in an inch of it's life, and then several inches more!!! Don't over do it.

 

[EMDDIESEL]

Have seen that done before. On my last truck i just put a brand new K&N on after 3 years and 86k. Was worth the 40 bucks as opposed to trying to clean and re oil my mangled K&N. I can afford that every 3 years.

 

[PUFF00]

cscpusher: This K&N has a connection opening of 3. 5” and the end of the boot is about 4. 5”. I used a PVC 3” to 4” adapter to couple the two. The 3” side of the PVC was a little small, so I cut a bike-tire inner tube and wrapped it around the outer part of the PVC to snug up the fit. It worked well--both sides had a good snug fit.

After reading some posts on air temp, I had been thinking it might not be the best thing to have this thing sitting in the open engine compartment, sucking in hot air. I’m not sure how big a deal this is. Perhaps the Psychotty is worth considering; or I may try wrapping the K&N with the outer sleeve and just leave it sitting in the open.

One problem I have with the different options is that I can’t find much data that indicates the differences in the various filtration methods. I have my seat of the pants perspective, but it would be great to have actual data on the difference between the different setups. For example, I’ve read that the Psycotty will decrease EGT by 100-200 degrees, but is that compared to the filter sitting open in the engine compartment or just the stock air box? Has anyone done this comparison?

Another thing is that I’m not actually sure the dust I saw in the boot came through the K&N. I saw some large particles on the inner boot wall, but it’s possible that these somehow got there as I was taking the boot off—we’ve had some dust storms lately and the engine compartment and outer boot had a lot of dust/dirt on them. There was a little grime on the silencer ring, but I didn’t wipe it down last time I had the boot off, so I’m not sure about that either. I need to be more methodical, so I can start making intelligent comparisons.

I guess oil analysis is really the only way to know if dust/dirt is getting through. I plan on doing this analysis anyway for the extended drain intervals, so I’ll have to start keeping a record and perhaps try the different filter methods. This will be a long-term analysis, but I’ll try to keep track of it and post what I find.

Anyway, thanks for the input.

I installed a K&N filter I purchased from Kragen Auto that fit perfectly. It had a special grease to seal the edges included.
I work in a new construction environment where dust, dirt, and mud is an every day occurance.
So, when I checked my turbo blades the other day, and they were as clean as they were when I had wiped them before I initially installed the K&N, I was happy.
The only thing I'm going to do different is change the oil every 5k miles, instead of every 7. 5k miles.

Be careful when putting the loose foam in your airbox. The stock filter uses adhesive to keep the foam from seperating and being sucked into the turbo.

 

[Newf Limo]

Puff, you should still have alot of spool up and alot of that sound you like! Makd sure you didn't knock a turbo-hose loose. Check with your hands not just your eyes. The Newf Limo is all stock with the silencer ring removed and I love the spool-up and that sound you get between shifts. BUT I went ALONG time with a leak and didn't have it and didn't know it! Check the blind spots with your fingers.

The foam would be on the "dirty" side of the paper filter so ingestion of foam would not be a worry.

 

[movintruck]

So if you want to keep the stock air box. The Amsoil filter is the way to go? Why so some of you think it's better than the K&N?
Also where can you get the oil to redue the filter after you clean it? Around here all I can find is the kits. With the cleaner and the oil. All I need is the oil.

Mad Max has a post about Donaldson filters. He is interested in the oil filter--I'm getting info from Donaldson on these--but after looking at their website, I'm interested in their air filters also. I'm going to see if I can use one of their EON air filters.

Anyone out there using one?

Puff,
Here is a picture of my airbox after 129,000 miles using the Amsoil "oil foam air filter.

Air filter element was cleaned about every 25,000 miles.

I get my filter oil frm www.summitracing.com Unless you have a good autoparts store who can special order it, they are your best bet.

Foam Air Filter or Fabric Filter(K&N Type) oil can be had @ any Mororcycle shop that sells Off Road Motorcycles. Several good brands out there Bell-Ray,Maxima,Silkoleen, PJ-1 are just a few that come to mind. Each type of Fitler requires it's own specific type of oil (ie: foam filter / fabric filter oil are NOT interchangeable)
