Hey guys,

I have had my SEGR installed by my mechanic now for 7-8 months and everything seems to be working well (no cel-engine runs great).

My question is, my mechanic didn't look at the EGR valve when he installed the SEGR. I am not sure if the EGR is completely closed, should we have checked this and put a plate / cover where the EGR valve goes. If the Jeep is running well and the SEGR is intalled properly, will this be sufficent to keep the EGR valve closed?

Can you guys please tell me what a Provent is? Is this a modification that I need to do? Do I already have one? As you can tell, I know nothing about this....(something to do with the turbo?)

I have 45,000 miles on the Libby. I have ordered a set of Samco hoses yesterday, the SEGR is done. I am just trying to get all the must do / fixes done. Anything else that is a must do?

Thanks for your help!

It most likely is seated closed? If it were open the engine would run like crap.

As long as the EGR is closed you wont get any sludge in the intake manifold, and the little bit of oil going through the manifold & CAC, will help clean out any accumulated pre SEGR sludge. I have 2 CRDs and I am not going to bother with all the maintenance of the Provent. GDE took his CAC apart and got very little oil out of it.

Now for the Pro-Provent response.

Not to hijack this thread but, I just purchased an SEGR but it does not have the pig tail that I need to wire up to plug into the unit. What it the name of that pig tail?

I have my maf unplugged at the moment to avoid my intake going to crap again, but is the EGR needed for start ups? Could we block it off like stated above?

x2, if the EGR were partially open the Jeep would run like crap and spit a lot of black smoke. If it's running fine, don't worry about it.



I'll provide that, of sorts. . .

IMHO, it is better to have only air going through your turbo, intercooler, and intake. I ran an EHM for a while, then switched to a Provent. I was worried a cop would see the smoke from the EHM and try to "help" me and end up giving me a ticket. I also got a good price on a Provent (thx KJ 119) and help installing it. (thx again KJ 119)

If you are running the Samco hoses, you have less to worry about as far as an oil-soak hose failure, but it really is your choice. If I were in your position, I would run the normal setup for a while, with SEGR, and let the CCV oil break up some of that sludge. Then at the next oil change, I would clean the MAP sensor and either do an EHM or a Provent.

I believe that is a custom pigtail. PM "TurboTim", "LocoCRD", or "UFO", they are the master SEGR builders.

Thanks for all the replies!

I do clean the map sensor every second oil change. Pardon my ignorance....what is the purpose of a Provent and a CCV? Why do we have sludge in our engine?

The CCV stands for Crank Case Vent, it is a black thing the size of a hockey puck on top of the engine. It allows vent gases produced by the movement of the pistons and combustion blow-by to escape the engine - otherwise it would blow up. It is vented into the intake before the turbo, to be "recombusted." Unfortunately for us CRD owners, the vent system allows a fine oil mist through, which then gets sucked into the intake - this causes intercooler hose failures and, when combined with the soot coming through the EGR valve, sludge in the intake.

The Provent filters the oil mist out to prevent hose damage and sludge production for those owners that have not disabled the EGR with an SEGR kit or a GDE tune.

Thanks for taking the time to reply to my question. Since I have an SEGR installed, do you think that I will be okay with out a Provent? I will also be installing Samco hoses soon, if that would make any difference?

This is how your intake could look if you left the EGR enabled, and allowed oil to mix with it. With the SEGR you should be just fine. This is from a VW TDI, they were notorious for this problem. You either got to stop the oil or the EGR. My last TDI had no EGR, I replaced it with a Dieselgeek race pipe.



Here is my VW manifold after I chemically cleaned it.

The Samco's are (more) oil resistant, so you should be fine. Some believe in continuing to let the oil flow through the intake, the oil will act as a solvent to break up any built-up sludge. I just prefer getting the oil out, it is a matter of personal preference. Just make sure you continue to monitor your MAP sensor.

How long have you had the SEGR installed?
