If you delete your EGR with the H&S wouldn't you have a less likely EGR failure as you wouldn't be putting the coolers through the heat cycles it would normally go through.

 

Wait a sec, are you talking about DELETING or disabling. As I understand the H&S disables the EGR. The valve ceases to cycle. No more soot rerouted back to your intake. That solves the problem of soot in the intake, should result in a cleaner burning engine. However, the coolant still runs through the EGR coolers and the posibility of one leaking and causing coolant in the oil and oil in the coolant remains.

If you delete the EGR coolers you remove that problem. That's a kit that is installed to block the holes, and the EGR coolers go in a box in storage. If you search "EGR removal" or something like that there is a thread on here with step by step instructions including pictures. It looks like a PITA job, but doable at home.

Or, if you upgrade to Bullit Proof brand EGR coolers you pretty much eliminate the problem and you can still return the truck to stock in a few hours. A bit pricey and still a PITA installation. I'm told if you just do the horizontal cooler that should cover you as the vertical seldom fails. You can google "bullit proof EGR" and find their web site.

There is also a tune available from KEM tunes that will recycle the EGR valve during idle time. That exercises the valve so that when you remove the H&S the valve will still work. But because the EGR doesn't reroute soot during idle it doesn't harm the intake. Just for the record, that is second hand information and as I read it I realize it makes no sense. If it doesn't cycle when the truck is at idle then what good is a program that lets it cycle at idle? I'll leave this here and maybe whomever told me that will come along and explain to us.

Hope this helps.

 

Sorry for the confusion Stanley but I was referring to just turning the egr off with the tuner, not deleting it.
My thought is that the coolers failed because of constant heat cycles from the hot EGR gas. If you turn the egr off, you won't have those hot gas's going through the cooler so you shouldn't heat cycle them as much, if at all, thus reducing the problem of the coolers leaking.

 

That makes sense to me. Not much point calling H&S. I don't know if their phones are bugged or what but I'm told they won't discuss anything that doesn't relate to off road use. I was gonna add on edit some stuff but I got distracted reading another thread. What I was going to say is that I'm not convinced the EGR coolers on the 6.4L are that big of a problem. I've been on here since June 09 and read pretty much every thread posted and I just don't recall many EGR coolers failing. There is a lot of talk about them being stopped, replaced or disabled, but it seems it was all a preemptive action. The 6L evidently had such a bad record with EGR failures that people just assumed it would carry over, but I'm not so sure that it did.

 

Well I'm more for the side off being safe plus you don't have all that unwanted soot going in the intake.

With the EGR open at idle it will reroute the soot. Thing is, there is little or no soot at idle. As soon as you touch the go pedal, EGR closed, no soot intake.

Got it, thanks. As for erring on the side of caution, I get that. I just hate to do all the work of taking it off and then having to put it back on to sell the truck.

 

Could one replace the stock intake elbow without removing the EGR's right away? I'm most likely going to delete the EGR's but not until January or February. Could I put a less restrictive intake elbow on for now and clean out all that crap from the manifold?

 

HMMMMMMMMMMMMMM> Since the mini has the EGR shut down would it matter, don't seem to me it would be a problem. Since it is shut down it seems to me one could pull the pipe and clean everything up and it would stay clean indefinately.

 

That's my thought. But my thoughts have been contradicted quite a few times, so I had to ask.

 

Scratch that. Wasn't thinking right. Verticle EGR connects to OEM intake elbow.
