Yea, it does happen on occasion. Just wanted to mention that in case you did have some power robbing situations to think about looking there as well.

 

For someone like me who is planning to keep this truck for the next ten years, it is well worth it. I understand your stance and highly respect your opinions but not sure why you get so worked up over people deleting the EGR cooler. I understand that EPA regulations are there but if I am not mistaken, you run a highly modified vehicle that I am pretty sure is not considered EPA friendly. I drive next to school buses and OTR trucks everyday that pollute 100 fold over mine so I am not worried about my truck that burns clean.

When I did mine there was no alternative, other than plugging the up pipe. If the bulletproof was out then I may have considered it....but it wasn't so I went with the delete and do not regret it.

 

It's not the fact of deleting the cooler that get's me as worked up as the fact that people seem to think that if they don't have emissions testing that it isn't illegal to delete the cooler. That's what gets me more then the actual deleting itself. They aren't aware of all of the ramnifications of their decision. That is what has also lead to somewhat of a black stain on the 6.0's reputation as well.


As the testing is done now, I'm clean. Not only by opacity but also that I do have my emissions equipment (and original ones at that, but I'm lucky I guess) fully functional. There are still gobs of power that you can get with these trucks and still have emissions controls. Requires a little more work maybe, a little more knowledge of what is going on, but very doable.

I think that there are a lot of misperceptions with the EGR delete.


Bare in mind as well, who knows were emissions regulations are going to be in 10 yrs. You might either have to put emissions controls back in or find a way to get rid of it or something like that. I don't think regulations are going to get easier within those 10 yrs that's for sure.

 

Well I think that I will go with the repair kit instead of the delete no one out there seamed to be able to say the delete add x amount of horsepower and soforth. Yes I will be tackeling the work mused I'm thinking about the oil cooler also any benefits from the bullet proof? I would like to add the coolant filter any good ones out there?

 

No, I doubt people will be able to do that. Mainly because when people do the EGR delete they also add other stuff to the truck as well that do directly add HP. What people would have to do is dyno it as a stock truck than with just the EGR detele and than as they add each additional modification dyno the truck again. Of course, they would also have to dyno it on the same machine with the same operator on days that have similiar aspects (barometric pressure, humidity, how far above sea level etc) as those all play a part. It's very tedious and people aren't going to go such lengths as that, but that's the kind of testing that you have to do to say definitively that it did add "X" amount of HP with regard to one specific mod. But unfortunately, people do more than one at a time for the most part.

 

the egr deleate is more of a reliablity mod than a preformance mod it may gain a little power IDK

FWIW I figure the egr cooler is causing some of the golden goo in the oil coolers . all that flash boiling and high exhaust temps aint good for the coolant. I did mine to try and save the oil cooler from clogging down the road

 

So basically the delete kit is more of a reliability issue than performance mod? What about the bullet proof egr cooler or the sinister cooler would those have the necessary flow to prevent failure in the future?

 

Not really. The underlying issue is the Oil Cooler and lack of flow to the EGR cooler. When the Oil Cooler get's plugged up you have an EGR cooler failure.

What happened is that people didn't realize that it was the oil cooler as the root cause or Ford didn't know or want to fix more parts than they had to while it was under warranty, so the next EGR cooler went. That led to people thinking that the EGR is the root cause when it really is the Oil Cooler.

You delete the EGR cooler you might still go digging around there to fix the oil cooler. It's less of a reliability mod then what most people think.

 

Personally, I agree with BLADE on this one, that the super heating of the coolant is causing degradation of coolant, which results in solids forming within the coolant that will in effect build up and clog the oil cooler. The root cause, IMO is the exposure of coolant to the extreme temps of the exhaust passing through the egr cooler. Removing the WART would discontinue the exposure of coolant to super heated exhaust gas. The oil cooler might be a crappy design, having too small of passages which can clog easily, but causing solids in the cooling system will certainly speed up the failure of the oil cooler, if my theory is correct... And I personally think it is, so I understand the thinking of deleting the EGR cooler. Once again, that mod is a personal decision and one needs to understand the risks of (I suppose) possibly getting caught, or finding that they one day need to bite the bullet and re-install it when/if smog inspections begin for diesels in their area.
Another good idea, to save your oil cooler from eventual failure, is to install a coolant filter.

 

IF BLADE and I are correct. I reiterate IF... Then the bullet proof cooler would still subject the coolant to exhaust gasses. Whether the Bullet Proof cooler might somehow protect the coolant by letting it flow through faster, or whatever, I have no idea. The bullet proof cooler, as I figure, is a better design to longevity of the EGR cooler, not the oil cooler. If the coolant is still being super heated, and formation of solids are occurring, then the oil cooler will still clog and fail.

 

Coolant is going to degrade no matter what, with or without the EGR Cooler. If you are worried that much about the degradation of the coolant do the flush every 50k instead of 100k (or whatever flush cycle suites you the most). Of course, it also depends on what type of coolant you use. You might even think of going to the Evan's Waterless Coolant (I don't know how good that is, I just know at this time it's an option).

Removing the EGR Cooler is still not going to solve the chance you take with the small passageways of the Oil Cooler. That's what you want to worry about. I know of 3 people here in town that still have had to have their oil coolers replaced despite not having an EGR Cooler and their coolers were still plugged. So there is still something else going on.

 

HMMMMM. how hot do you think it is surrounding the cylinders?

 

very true but the coolant has better flow through the heads the egr cooler gets whatever the plugged oil cooler will let it have
alot better odds of boiling coolant in the egr cooler than around the heads

just my.02

 

some still have the problem of casting sand and need a coolant filter

I think that some had there oil cooler replaced but didnt get a good flush and just plugged the new oil cooler

did any of those guys cut the second oil cooler apart to see what was clogging it up

 

It still degrades the coolant. Better flow or not, it is "stress" to the coolant. Causes precipitates to form and thus plugged oil cooler.

It's a vicious cycle actually and there really isn't a 100% cure, which is what people are hocking with the EGR delete.
