I know this has been talked about here before, I have read a lot about this issue, but I am still confused and wanting to settle the process once and for all for myself. So here is what I have.


My current situation is I have my cooler installed, my EGR valve installed, but turned off by my SCT X4.


Here is my current thought process... correct me if what I am saying is wrong please.


So my Delta T's are between 6-8 degrees almost all the time, sometimes reaching 10 degrees when it is really cold out. My engine oil temps are usually around 190-198, my coolant temps are usually between 184-192.


With that said, I think my EGR cooler and oil cooler are good to go. So do you think that it would work for me to put in a EGR valve plug like this: http://www.ebay.com/itm/Ford-6-0-Die...D270630119699] No I am not the seller, nor do I get anything from it, I am just trying to get answers for my truck and I found that one.


My thought process about this is that if I just keep the heat (exhaust) out of my EGR cooler then it will not get hot and cause the coolant in the EGR cooler to build up due to cooking. Thus the EGR cooler would not get any worse than it is right now, and would last a long time.

Also I am running CAT-1 ELC coolant with a coolant filtration system that I change the filters on about twice a year. My EGR valve is turned off with my SCT X4 also.

 

No, I would not remove the EGR valve and install the block off plate, the EGR valve helps control fan operation!

 

I think I got my answer, bismic helped me on another forum, but if anyone has anything to add, I am willing to listen.

 

Yes, but you can keep it plugged in and just zip tied out of the way, right? I will probably just keep it installed, do the BPD EGR cooler, an OEM oil cooler, and then stud the heads.


Thanks.

 

Don't get me wrong .......... I would love to have a BPD oil cooler also. If you have the $$'s they are nice!

Glad you found the ebay seller for the plug, I just couldn't find the old link! As for me, I just keep the EGR valve installed and rely on the tune to keep it closed.

 

Yes, and thanks for the help, I really appreciate it. Nice to see you here also, I just found this site.

 

And the answer is; keep the cooler, block the exhaust from coming in and leave the valve in place turned off by the tune..

Enjoy the truck.

 

So you mean weld up the cooler exhaust in and out (is this the best way?), leave it in place, and leave the valve in, but deleted?

 

Yes. Weld up both sides of the cooler with 1/8" or thicker 304 stainless. DO NOT USE FREEZE PLUGS!!
Something I've always curious about is there is a small piece of metal inside the exhaust pipe to help divert exhaust gasses into the cooler. I left mine in there and have only seen 1 person question it and remove it. Mines been working fine for over 15,000 miles.

 

Got it, so you guys leave it hooked up to the coolant right?

 

Yes. Only blocking exhaust gasses.

 

That's the general idea. This leaves it in tact for coolant flow and some claim up-pipe support. You will need to use a tuner to turn the EGR valve off, leave it plugged in for fan operation and it passes visual inspections.

It lessens the chance of a rupture by removing the exhaust entry.

 

Got it, thanks. I have already deleted the valve with my X4, and I do not have smog at all, so no worries there.

 

This ran me ~$45... 1/8"x2"x8" 304SS & 308SS flux cored mig wire for my Lincoln. I plan on pressurizing the coolant side of the cooler with 20psi in a tub of water before I weld it to make sure the coolant side is good. Probably not necessary since it'll be completely sealed from the exhaust. If it's leaking then I'll give the exhaust side a good cleaning to prevent the exhaust soot inside from mucking up the new coolant.
