I ordered one today from case, and I am attempting to get the cummins numbers if and when I do I will post the numbers if sombody hasn't by then.

I went to a case dealer and used the part numbers from the pdf file on the first page. Case was backordered for who knows how long and Cummins had two remaining in stock. I had the case dealer order the valve covers from cummins and the breather and gasket from case. I like the fact that my truck shares it's engine with dozers and backhoes and generators.

not as extremely functional as four baffled chrome breathers though... I'll take 4 times the crank case breathing at 1/5th the cost.

I will readily admit, they have a very nice OEM look to them, and I've spent a lot of money in the name of minor asthetics that most wouldn't ever really notice, but principle won't let me spend that much when I can get more function for considerably less money

My wife always tells me that I spend money like I have it!

Myself...
I'd like to hear what you base this fact on?.Have you done a pressure test with your exiting crankcase pressure to verify that these are not as good as the old drill and shove them in chromie breathers?.I am guessing that you never looked at one of these close up to see the inners and how much area they have for pressure ventilation,plus the added benefit of making sure the oil stays in the motor and not out through the push in breathers.Hmmmm.......

Yeah, I was also going to say just that. After seeing two different trucks, one with push in breathers and another with actual welded on tubes/clamped on breathers that both trucks blew them off and had oil everywhere...I would rather have this setup. I just picked mine up the other day and are already on the truck but havn't seen how they work yet because its not quite ready to fire yet. I will give details next weekend if I get it up and running for its first pull. I am about half done doing all the plumbing jobs but its take a while.

I've had good luck with the local peterbilt shop once I get them a cummins engine number they pull up any parts I want. Used to work at the case dealer a few years ago so I might be able to get a little price break.

All of us here are still waiting for your answer on your comments???......

Finally snapped some new pics of the engine today and got one of the valve covers on mine. If you are running non stock lines bent for water injection you will only be able to run two covers instead of three. If I wouldn't have been running the modified lines than I could have had 3 of them. I don't have the hoses on them yet but its nice that you can just pop the locating bushing in order to rotate the breather so it can point in a different direction. Mine were of the same looking aluminum and took a polish well but after 10 minutes I decieded it wasn't worth it for me and just painted my two polished stock ones instead.

All in all I am very happy with them and I will have an update hopefully this weekend on how they work!

To see the pic you will have to click this link to jump to the competition forum to see it seeing I already posted it there.

The "B series " ( 3.9 and 5.9 ) engine was a joint venture between Cummins and Case. Some parts are used only certain models (like Dodges ) but the basic parts, bearings gasket etc are common. In alot of cases ( pardon the pun ) you just drop the 3 from the front of the Cummins p/n and add a J. Cummins can't break down a Case serial number for example. Shadrach

Looks great Ryan!!!!

Good luck this weekend

This breather setup is also used on the Cummins 4.5 ( 4 cyl ) and 6.7( 6 cyl ) industrial engines. The Cummins option numbers are VC97006 for the valve cover and BR9135 for the breather. If you want to buy or price them out from your local Cummins dealer give them these option numbers and they will be able to look up the part numbers. Shadrach

The cummins part numbers are as follows, valve cover 2830784, breather 4899194, and breather seal 4899195. I wont post the breather bolts as they are just metric bolts.

sorry, I've been offshore...

anyhow, with that setup you can only vent two valve covers... you're breathing through a couple pushrod holes with pushrods in them. not sure what the flow rating on those breathers are, but you can only breathe so much through the holes in the head. haven't looked under the valve covers in a minute, not sure if there are other drain backs.

anyhow, with the chromies, you can run four breathers... one of the OEM valve covers and breather setups costs $100, right? and you can only breathe as much as the holes in the cyl head will allow. I bought four chromies w/ gromets for right ~$40... four times the holes in the head = four times the flow. roughly
