Crankcase Exhaust Venturi WANT YOUR CUMMINS TO STOP LEAKING ???

[@johnclamshellsp1969]

Thanks for the Cummins blow-by trick. I will be doing this on my bus very soon. What a perfect way to elminate so many issues. I too am plagued with rear main seal leaking/drip (new)at idle/load from blowby.

Crankcase evac system. Drag racers been doing it forever.👍

[@JC-gw3yo]

and if you want to buy these parts instead of making them, Moroso sells a crankcase evacuation kit. I believe it was first used by the pro stock guys. For best performance, should be installed past the muffler, especially if the muffler is restrictive

Was at your shop today your truck looks sweet in person!

I love your tips an tricks 👌 keep it up 👍👍

I was watching another one of your videos and wanted to give it a like and a comment. I'm already subscribed. Boobtube in its usual manner dumped me off, after signing in to like and comment, at another one of your videos. And that was fine with me as I found another one of your videos, this one, to like and comment on. Love all your videos, love my 12v and appreciate you passing on your knowledge, experience and style. Yeah, I said style. Keep up the good work, love my shirts I bought and the WEALTH of information on all kinds of info I can use.

[@kevinarmitage1538]

Can I plug the camshaft area OEM breather and use a valve cover breather off the Case tractor tapped into the exhaust? It should keep the air suspended oil from escaping from the OEM breather.

[@CUTTERUPROB]

You can use the valve cover type and block the other off

[@petermolnar8667]

Our Massey uses the same for the air cleaner to prevent dust deposits is the housing

[@jimkillen1065]

That's a great idea . A while back I has a leak on my transfer case from the shifter shaft and for a bit I thought about install the vacuum line hooked to the vent of tc . . I got the damn leak fixed but this is a good idea as my 95 has a few small leaks that a irritation

[@mylesswann530]

Any concern of heat soak through the fittings to the rubber hose? Hose recommendations?

[@CUTTERUPROB]

I have never had a issue. I just use heater hose hose

[@reitzy69]

My 12v don't really leak...yet n I know it eventually will...i was going to do a catch can...but I like this idea far better...going to do this set-up

[@marckilpatrick]

How your brain works teaching is how my brain works all the time . Cheers bud !

[@SteveLShannon]

That's a great idea. I've got just a simple filter on the CCV.

[@rippleeffect3910]

Thanks for this Rob. Will it hurt the motor to run just a catch can on the frame rail for drips? If a person can't get to the exhaust side for a while. Just wondering if not properly scavenging with a venturi will build presure.

[@CUTTERUPROB]

Nope that just fine to do it that why

[@elroyelblander6277]

Good stuff as always man👍👍👊

[@davidknowlton6249]

I know I'm overthinking it, but could you go into the turbo elbow from a vented valve cover? In my head it looks clean and the elbow could be removed but I think its cast so hard to wield?

[@CUTTERUPROB]

On the air take side you can. But then the junk goes into the turbo. On the pressure side you can’t

[@alexsails80]

Hi Rob. Just watched this one again. What hose material can take the heat? In my application the venturi tube would enter the exhaust pipe about 12 inches from the turbo outlet flange.

[@CUTTERUPROB]

I am not sure on that one. I have always made it down steam a bit. I am sure they’re is something that would work. Maybe talk to your local hydro shop.

[@michaeldixon908]

Dude, you should make and market a kit. Great idea

[@creativeloafer9792]

Been thinking about doing this to my 02 24V. It has that ridiculous plastic catch can mounted to the front of the engine. Maybe get some good hydraulic hose and route to beyond the muffler.

[@Cornelius.18]

I’m thinking of doing the same thing. On the same truck. Have you done it and did it work?

[@creativeloafer9792]

I haven’t got around to it yet. Wayyyy too many projects, but a pile of new parts awaits for the ‘02. Will definitely post results tho

[@brcron007]

Rob, could this trick be used on my close to stock 1st Gen (92 5.9 Cummins) crew cab I'm building. Just running the crankcase hose to the exhaust. Making it run better and no drip sounds like a positive to me. The only thing you didn't mention was about a type of "high heat hose" to use? Thanks again for I think a Great tip 👍

[@CUTTERUPROB]

Yes it can

[@soulthatcreates]

Question, would it be a good idea to put a check valve on the venturi tube? Or not necessary?

[@TyReynolds-s9n]

Do you have a video related to vacuum pump/ vacuum leaks causing “blow by” or excess pressure?

[@CUTTERUPROB]

I don’t yet

[@JRasS14]

12v have the breather vent for valve cover and keating tappet cover with two baffled 12an breather ports, was planning on doing a catch can with breather filter to it. Maybe I could do the drain to exhaust and keep it open. Or just do the tappet cover breathers straight exhaust. What would you recommend?

[@preachers4135]

I have a similar set up and same question. Will two “Y” adapters work, should we use a larger pipe at the Venturi or decrease the number of ventilation points?

[@CUTTERUPROB]

You guys. Am just tie them together if you want. But I find you can just use one. If you have more then one pick the highest one on the engine

[@preachers4135]

@@CUTTERUPROB Thanks Rob! I’m adding this to my list of “to does” that will most likely take me way to long to get around to than actually just knocking it out.

[@bobirving6052]

Great ideas! Thanks Rob 👍

[@bigmurph1447]

I have add a second vent to my 12v. Since I have compounds. What happens if u have no exhaust like a hood stack like most race trucks or pulling trucks.

[@preachers4135]

How long is your hood stack? You could try putting the venturi in the hood stack but if it’s a short stack it might not have enough velocity to create a vacuum.

[@CUTTERUPROB]

I would add a Venturi and a catch can tied into it and just use one vent line

[@ChaosViper67]

Nice, I've always wanted to do this.

[@CarriganHunter]

Do you use a check value?

[@darrinstone49]

I added the kits from jegs or summit that have the check valves in them & attached the breathers in the Valve cover on my 24V

[@davidknowlton6249]

Why the exhaust not the intake?

[@CUTTERUPROB]

You can use the intake it you want the engine to eat the junk coming out
