I had mine done at bulletproof diesel in Mesa AZ.

Mine was running fine, so when I picked it up I noticed no difference except for swapping the OEM liquid cooled oil cooler for an air cooled one.

I immediately noticed cool oil temps which is exactly what I wanted.

Within a month or two, the starter and a month after that, the alternator went.

I did not have the shop fix the oil leak, which would be an engine out fix. That put a few drops on the ground for the next 11 years until I sold it.

Also not part of the bulletproof if was the plastic fuel pickup

As far as the bulletproofing itself, I had no issues except an added oil base started to develop a wear mark. That did not effect me, but eventually it would have developed an engine oil emptying leak.

The air cooled oil cooler added a couple of hoses to relocate the oil cooling to a small radiator in front of the coolant radiator. After several years, one of these added oil hoses started to rub on an engine part and start to wear through the rubber.

I am not a fan of tuning.

I have an SCT4 and did not realize that the governor was disabled in the tune I had. When I went to get an emissions check, part of the test was flooring the accelerator. The revs went well above 4k and the engine started to skip.

I had the tune in the first place to fix excessive EGTs, but the tune hid whatever was causing the high EGTs. I’d spent hundreds of my own hours looking for the problem, and thousands of dollars at a shop and the tuner was what worked.

 

As far as starters go, I wouldn't say that the 6.0L starters are all that unreliable, but the upgrade to the 6.4L starter, or even faster - the 6.7L starter, are sure nice upgrades!

Changing the fuel tank pickup tube is a pain, but the plastic breaking down seems common and I doubt that it is related to miles driven. That also might be a consideration for a change or upgrade.

With age and heat, the plastic "Y" under the degas bottle sometimes fails. There is a stainless substitute that we can link you to.

 

Sorry for your loss.

Given its history, I would have left it alone, at least for a while, to build a running history. Once it went through its sea trials, if nothing stood out, my first stage of prevention would have been a coolant flush, oil cooler, BPD EGR cooler, turbo cleaning, blue spring, HFCM cover, and replacing the fuel pick-up. And then set up monitoring, including fuel pressure, coolant pressure, and dual EGT, along with getting Forscan for troubleshooting and some OBD2 monitoring.

I’d have a hard time putting a tune in there.

 

Still doing well with that DieselSite HPOP @joe blow ? How many miles on it?

 

Unlimited Diesel Performance in Bremen, Ohio is doing the work. It has an excellent reputation. I will delay the ICP and IRP. I will have the gauges installed. I kept the old FICM for future backup. I do not know the manufacturer of the EGR cooler. The diesel shops here will not do an EGR delete due to federal law. I have to agree with them.

 

Thanks for the shop info. Also, it is good to have a spare FICM, in my opinion anyway. I would be a little "wary" of anything other than an EGR cooler from BPD. The welded tube design is about all that holds up.
