While replacinng up pipe due to leak should I go ahead and replace oil cooler while back in there? Coolant is flushed , oil is changed to 5w 40 , blue spring installed(which seemed to make difference immediately!) And scangaue in ! Scangauge is still showing around 198 Eot and 188 ect .
Also looking at exhausted upgrade and saw a banks system that looked pretty good and suggestions? According to scangauge ebp is like 21 at 60 mph does that sound right?
Thanks for everyone's help makes these project much easier!
Any suggestions are appreciated!

 

Guess I can't edit on phone.
Also should I go ahead and put plug in up pipe to block off egr ?!

 

What year is your truck?

 

The truck is an 03 f250

 

those deltas don't look bad enough to me, to warrant the complete dissasembly that is required to get to the oil cooler. also the amount of time your truck would be down is about 2-3 days to do the oil cooler properly taking your time, trust me i'm in the process of it now, and good luck with the up-pipes, those are a PITA to get to, think of superman laying across your engine bay. when it is consistantly over 15 degrees i would consider it, mine was at about 37 degrees when i pulled the trigger to do it

 

I think your 10 degree spread may be rite on the verge of needing to be replaced. Warmer ambient temps and having something in tow will both make your delta even larger. Additionally, the longer you run with a questionable oil cooler, the greater the chance that you will need to replace you EGR cooler.

Are you trying to knock out all the isses at once, or are you ok with monitoring the ECT/EOTs and knowing you will probably be back under the hood to replace the oil cooler later on?

The up pipe really isnt anywhere near the oil cooler, so its replacement should have little bearing on your decision about your oil cooler R&R, except for you'll have your tools out and your head under the hood.

 

I think I will continue to monitor ! I am doing plenty other things to it right now and money doesn't grow on Trees! lol
What your thoughts on blocking egr with plug in up pipe ?

 

Money doesn't grow on trees in my neck of the woods either, so I understand where you're coming from.

Your 03 has the round cylinder-shaped EGR cooler, correct? If so, that EGR cooler is more robust and less failure prone than the later square shaped one. So I guess i wouldn't worry about it failing quite as quickly due to oil cooler blockage or hot exhaust temps.

Do you have smog testing where you live? If not, you can certainly block the up-pipe to EGR cooler connection. I think I'd probably plug it, if smog testing isn't a concern and your already going through the effort of replacing the up-pipe. Make sure you still clamp the up-pipe to EGR cooler connection though. I seem to recall that not doing so can lead to cracks in the up-pipe bellows.

Beyond that, you could also eventually install a spool valve in place of the EGR valve, to eliminate the possibility of EGR valve failure (and to close off the other end of the EGR cooler). However, you should properly investigate this modification, as newer programming versions may be affected. I don't think it will on a 2003, but it might.

FYI... here's what I did to my 03 several years ago....

The spool valve I put in place of the EGR valve:


The spool valve installed, and the EGR valve bolted to the intake elbow and still plugged into the computer system...


Butchering the EGR cooler to make a crackpipe...


The crack pipe I made out of my EGR cooler....


Crack pipe bolted to the intake...


Hose installed from oil cooler to crack pipe...


if you know what you're looking for, you can see the plugged EGR port on the up-pipe in this picture...


I'm not claiming this is the right thing to do. Like I mentioned before, newer flashes may cause this type of modification to be an issue (fan operation or boost may now be affected, I don't know for sure but it's possible). Also, the rubber hose I ran from the oil cooler to the crackpipe may have been prone to failure, as most of the EGR delete "kits" that are available have a metal pipe instead.

Just a few ideas for you.

 

Because of the high prices, I generally don't consider the Banks products, but I have a Banks exhaust and love it. For me it is a great sound - deep, but not all that loud.
