CDR valve relocated to stop oil suction......

[ak diesel driver]

the cdr is normally open and only closes when it gets vacuum from the turbo in a high boost scenario. It does create vacuum there even under light loads. The further you go towards the air cleaner the less the vacuum because of the larger diameter of the tubing

HMMM.... That would be easier but isn't the CDR only "Open" when the turbo pulls air? That is why I say a hose with some sort of male to male barb in one end stuck in the grommet would be a better way to vent.

I am not really looking to argue about it or anything, I plan to use my CDR ran the way it was put by the factory with a provent added if blow by is THAT BAD.

Everyone has their own way of doing things and I support each way if that makes the user happy.

CDR is open 99% of the time,it closes only under high boost but will open again when boost is sustained ,IE crankcase pressure rise with blowby caused by boost.
I would use either the CDR or the Provent,not both.Preferably neither.
If i had to do it again i would just pipe the CDR to the world instead of buying the Provent.

Not arguing,...Just saying

600 miles and has made a diff in drips. not sure about tube leaks yet though. going to get a 98 black hood bc of an incident i caused w/ mine. damaged beyond repair. $70.00, paint and condition is good. an hour drive each way though.

 

[deejaaa]

cleaned off the turbo tube and cleaned the air filter. gonna see if there is any sign of oil blow after the week. oil level was still on the mark.

 

[deejaaa]

so far so good. haven't noticed any excess oil consumption.

I didn't like all that oil and junk goin back through my turbo and into my engine either, my cdr is still in the valve cover with a hose that takes it near the drivers tire, I can notice blow by sometimes, but never have any oil drips of any kind.

In trucking, they call that a draft tube (or down tube). A guy I used to work with had this slick idea. He bought a 4" dia tube, aprox 1' tall. Top had two bungs on it. Bottom was sealed, other than a petcock that allowed you to drain out the collected oil. From the top, one bung went to valve cover and the other went down by the axle. Idea was instead of venting near the ground and potentially a mess, this container was plumbed in the middle. Every so often he'd drain it. Of course it was polished...

Not a bad idea IMO, I might try something of this nature on one of my high blow by trucks.

I wonder If that oil can be dumped back into the engine??

Yes it could, my Isuzu has a canister that catches vapor and drains oil back to engine any excess gets to see the highway.

Yep.. the 'Provent' has a drain back that is plumbed into the crankcase.

I came up with a 'kinda-sorta' Provent that achieves basically the same thing..

Keeping the oil IN the engine is a GOOD thing.

Letting the pressure OUT is better still.

Do both and life is good.

Has anyone tried using a crankcase filter like what is used on the older gas motors inserted into the hole where the CDR is?

Back at the place member Texas Diesel Guy did just that. I believe he went back to the cdr.
