Need to replace the metal mesh filler in my breather and wondered what's wrong with using some ordinary fiberglass window screen. Just wad up a hand full and stuff in there? I have made a slip over foam outside filter.
Kitchen cookware "scrubbies" -- the stainless-steel version, not the copper version. Scotch Brite, Chore Boy, etc, brand.

Why not just buy a proper filter?
You wouldn't ball up a bunch of crap and shove it in your car intake and call it a day.
Mainesail's site and this one discuss a K+N air filter element. Did it on my old C34 and now have it on the C400. Works great.
Stainless scrubbies (crap) worked perfect. Thanks for the help

Did you oil them (dust catcher)?
Unnecessary if you have your crankcase vent hose routed to the air intake? ( a must to reduce odor and bilge gunk.)

Stainless scrubby has no real filtering ability and if a piece of that stuff breaks off ...m
They used to use that stuff on gas engines to protect against backfiring flames through the carburetor. Don't see how it makes any sense on a diesel?

That's why the guts are oiled. And there should be a stainless mesh screen in the bottom of the "container."
The whole unit is really no more than a noise attenuator -- think the air really needs 'filtering"? -- we're not on a dusty highway like an auto or in a field like a tractor.

My engine compartment located under the companionway stairs awalys seems to accumulate lots of dust and dirt. It could be different where you are?
As part of my spring commisioning tasks I soak the metal mesh filter in a container of diesel, shake it out and let it dry. The diesel in the container is quite dirty after that, so I'm encouraged to keep doing it. I'm sure a dusty field would be much worse. Sill, seems like there are contaminants in the engine compartment. I have noticed that since I installed the vent hose fliter and ran it into the air filter housing, the metal mesh doesn't seem as dirty. So maybe a big source of the apparent contamination was actually from the vent hose discharge, despite using Ron's "foam pad in a cup" method previously, which did work.

I replaced the whole thing with a K & N RU 2450 a couple of years ago and haven't looked back.
I also installed the K&N RU2450 and it's been working great.

The last 2 posts are what I am talking about....steel or bronze mesh sitting on top of the intake manifold....not.

I'm not suggesting anyone try this, but...... in college I loaned by Skylark (OHV V6) to my brother to go on a job interview. When he returned it, he said it started "running rough." hmmmm......
When I pulled the valve cover, an intake valve was missing -- its retainer had let go and the valve dropped into the cylinder. When I tore it down, no valve -- it had been chewed up and spit it out the exhaust, with no more than a slight dent in the top if the piston.
go figure!

You're suggesting a few metal bits is good for its constitution (and oil/compression rings)?
Like vitamins.

If you don't mind paying...CD has the whole canister assembly Air Filter w/Aluminum Honeycomb Universal Diesel (#Z3428): $62.90

What's the purpose of buying a whole new cannister w/ aluminum innards, when for $2 you can replace the honeycomb with stainless steel?

Not advocating, just offering info. Who knows, an assembly could be missing, someone could be restoring???

Ahhhh ok, I thought that was to GWP, who had the enclosure, missing the innards. 8)

What a nice clean engine, Rick!
What type hose barb is on the crankcase breather -- a threaded or push in, or....?
Ken
how necessary is it to have that foam silencing material around the filter, mine crumbled off would like some thoughts on using a green foam filter you buy for small engines, checking material stores, walmart ect. can't find material that equates to what was on. been thinking on going to that K&N filter. but is that overkill to what is oem.
What is the black box on the right bulkhead for? Jon W.

YBYC - it's primarily for noise. Some 11 years ago mine was all stretched out and wouldn't stay in place, so I sent the Admiral off with it in hand to find a cheap (reasonably) replacement. She came back with a matching one in an hour for a couple boat bucks -- from Lowes or Wally or some other big box. I didn't even need to trim the width.
Check with your local mower or other small engine repair shop -- if they don't have one hanging on the rack they can order an inexpensive copy.

QuoteWhat type hose barb is on the crankcase breather -- a threaded or push in, or....?
Ken, it's threaded. I don't recall the size hole I drilled into the rubber top, but it screwed in very tight. I was going to put a nylon nut on it but never saw the need. besides, if the nut came loose, it would fall into the intake.
QuoteWhat is the black box on the right bulkhead for?
Jon, IIRC, it's a RF noise reducer installed by the PO. I don't know much about it but I assume he installed because he had an SSB on the boat at the time, but I may be incorrect.
Here's a better picture:

I'm getting ready to redo the connections as they're looking worn..

Rick, yeah as long as it's tight, why bother?
If it ever needed a nut, I would deform the male threads using a soldering iron, sorts as I recommend in my TechWiki article if using a brass fitting. Alternately, I've seen some insert a heavy rubber grommet, and use a push in fitting.
Cheers,
Ken
