Additional Crankcase Venting

[bgilbert]

Looking to add some additional crankcase venting on my 91.5. On my 89 I have a nice $50 oil fill and crankcase breather/two in one unit on the timing cover. I'd like to save some money on that right now, plus I don't get through Indy anymore to stop in at the blue C where I would just save time and hassle and spend some money. I'm not an ebayer, or I could wait and wait on a 2nd gen 24 valve breather. I'm pretty sure I've seen some pulling trucks with bungs of some sort welded to the top of 2-3 of their valve covers, then hose routed down the side of the engine. I'm thinking about doing this, until I've learned the valve covers are aluminum and you can't weld steel fittings to aluminum . Nobody in town has any aluminum fittings, let alone a weld in bung.

What's a guy to do? After installing the Pro52 on my auto truck, the 91.5, and taking a spin, oh and after changing my underwear, I seen where I blew some oil out the rear of the tappet cover. Would I lose a bunch of oil with an aluminum fitting on top of one or two valve covers? Any other ideas?

a bulkhead type fitting might work? just drill a hole and bolt it on. not sure if i've seen bulkheads that big that weren't plastic, but i'm sure they're out there.

CP, good lord, $60+$17 shipping . I happen to have a very good medium duty junkyard locally and there are just dozens of B series valve covers laying around, probly could pick one up no charge. I have a few laying around myself if I screw one up.

AP, I'll have to look into something at Autozone.

CK, I don't like the looks of the filter on the oil fill.

Swank, I never thought of the bulkhead idea. I'm good at plumbing fittings, I might just do that. With the long male/male bulkhead, one would have to cut it off inside the valve cover to fit, not a problem. I only wonder if it would splash oil out real bad with no filter or baffle..?

If you use a large enough diameter fitting, the air flow will be slower than a small one. More oil should drop out.
Or, run it up higher before going down.

Bill at work we put one of the push in gromets in the #6 valve cover and stuck a PCV valve in it with a tube hanging down the side of the block on one of our Rowcats.

Got a Cummins PN for those valve covers?

[JAyers]

Yes but its actually a case PN. Im pretty sure they arent made by cummins. Ill get it when i get home, im at college right now.

[bgilbert]

Tank, yeah I'm glad you brought those up. There was a big post about them WITH all the part numbers on TDR awhile back.. well maybe a year ago. I'm no longer a member there, and can't do an archive search, or I'd look them up. If I remember right they weren't cheap. I would be interested in part numbers Josh when you get to them.

Or PETE, how bout you look them up???!!!

[PToombs]

Ok, but I want an extra $2 to babysit! We all told you not to give up the subscription, but did you listen? Nooooo!

[bgilbert]

Beat ya to it Pete. Here is a link from compD: http://www.competitiondiesel.com/forums ... t=breather

I figured I'd find them over there no problem. Pricey!! Pete get to work on them, remember J first, get back to me, please!!?

[JAyers]

Heres the list of part numbers, the only problem is ive got two numbers that have valve cover wrote next to them. Ive got a pretty good idea which one is right. lol I would go back to TDR but my subscription has also ran out. This is the quanity you will need for one double valve cover w/ one breather

#2830784 double valve cover w/ breather

#2852032 alternate part # if the one above isnt correct but i think its just a single valve cover.

#2852531 Breather

#2852028 Breather gasket

3 #899110 - alt #4899092 Breather screws, they are both diff threads. I used the first P/N.

These covers use a different bolt with a nice isolator to hold down the cover. Some people just use a washer with the stock bolt but I went ahead and went with the different bolt and isolator. I got tired of replacing rubber orings.
