Seeking some advice...

[Nu2Ford]

2006 f250 CC lariat 136k stock for the most part. I added a coolant filer 2 months ago. The eot/ect delta is running a larger gap now a days 10-14. it's has the stock oil and egr coolers according to original owner.

I've decided to do the EGR and Oil cooler at the local Ford dealer. Gonna do the Bullet Proof cooler and stock Oil cooler since I'm in California. Gonna change the STC (?) connector as well.

What else should I have done while it's apart?

The second part to this is that I'd like to try a tune. I don't want to blow my head gaskets, ruin my transmission, etc. Gearhead/ Innovative are names that get thrown around.

Are they safe to run? I don't beat on my truck. Just thought it would be fun to try since I'm well out of warranty and I'm taking steps to fix some weak spots.

I don't have a lift or tires. Not planning on any. I do need to tow on occasion so I need to maintain that ability.

Need some sound conservative and prudent advice on both questions. Thanks.

If you're out of warranty why have ford do the work? I'm 99% that you can do a full egr delete just leave or put back the valve when it's time for visual inspection. Maybe consider flushing the block with restore and restore + before installing a new oil cooler? Or else, over time, oil coolers will continually fail. Where are you in ca?

[Nu2Ford]

I'm in Santa Cruz, but willing to drive if you can recommend a a place. Yes, the delete would be ideal, but don't want any future emissions hassle.

Would the block still need flushing after all this time? It's had the coolant changed 3 times. I guess I figured whatever was in there would be long gone.

I will PM you where to take your truck. You don't have to go far. The tech at the dealership used to be a moderator and "tech" on this site but as since moved on. Yea the block needs to be flushed in every 6.0....even the 6.4 come with casting sand. I messed up and did not do a restore flush before my studs. But I don't remember in 2009 if people knew about restore and restore+ flushes. My deltas were 30* difference and I got a new oil cooler in the summer of 2009. It will have to be replaced after you flush. If it's had the "coolant changed" 3 times then I'm guessing it was just a dealer version of a flush which more than likely will just clog the oil cooler when they do it. I had the dealer do a flush about a year before I got the studs done and I personally think that is why my deltas were 30* difference. Restore and restore+ flush, studs, coolant filter and egr delete and IMO that is pretty bulletproof.

The “stealth EGR delete” is to pull the cooler, weld the exhaust and intake manifold ports shut and reinstall. Then leave the valve in place so that no trouble codes are sent to the computer and your fan and turbo continue to function correctly.

This is a super cheap mod. This will solve all of your EGR related issues, it looks stock and the smog inspection will be easy to pass.

[Nu2Ford]

Will the "stealth set up" throw a code? Are there any other precautions to take besides just welding it shut.

[HAM_RADIO_MAN]

No nope no codes. here a link for more info on the topic

No longer a 6.0 virgin. New STC, Cleaned turbo, welded EGR cooler closed. PIC's

I went with a sinister mfg egr cooler and a stock oil cooler. I did it by myself, but my truck was down for a few days. Also had to clean out my EGR valve. I can't recommend a "stealth" setup, don't want to be responsible for you getting in trouble. I only live an hour and a half east of you. Here's a shop just north of us in Concord: left coast diesel. I've never had service there, but I like to know my options in case something is above my skill/tool set. If you're gonna keep this truck, I'd go all the way in for the headstuds and hit everything on the way out.

I don't think left coast will install an egr delete.
