If the cooler fails, it makes a giant mess and can pop the head gaskets.
Int. the truck when hot would run rough at idle and low rpm. Ran all the tests; egr valve pos. test failed. My dad pulled the EGR and found it carbon-ed up big time. I told him how to clean it and to see what would happen. Turns out the ICP connector was causing the problem. Unplug and replug fixed it and i have a new connector for him.

Wouldn't hurt to test the FICM either, they are known to fail. It's easy enough to do and you may not notice it slowly dying over time, it will cause poor acceleration and poor mileage

Its possible the turbo is rusting. My mom doesnt ride it hard.
It gets all the engine maint. that it should get.
I have not driven it to see how bad the lag really is, but dad is pretty good about noticing/gauging it.

Yes, these 6.0's need to be worked and driven. Long idling time and driving like grandma kill these turbos

I told him to block off the cooler and take it out, in case he needs it for the sniffer.
take the baffle out the downpipe and take off the muffler.
If he needed more, put a programmer on it. But it could get him in to trouble; which is what were trying to avoid.

Where do you live? Cali is really the only place they do actual visual emissions testing, anywhere else I'd lose the cooler and valve. I don't know how anyone drives a stock 6.0. Once you've driven a tuned 6.0, you wont go back! Also what baffle in the downpipe? There shouldn't be one... just the cat and muffler. You can get deletes for both for around $100 total, or just get a 4" turbo back, which is what I recommend.

Most of the heads were flat enough according to ford spec, but when a rod lets go the valves are trash and so is the head so it got replaced.

Yeah my heads were flat according to ford, when they put my ARP's in for me, that was the SHORTEST amount of time I've had headgaksets stay together. Blew the gaskets 3x now. Once with dealer installed ARP's, their flatness spec sucks and new heads come in out of spec sometimes.

I know what you guys are talking about with the flower pattern. I did not know it was from timing; i was told it was from too much fuel. When the 6.4 came around there was alot of that going on, along with toast bottom ends.

Correct, the injector is told to dispense a certain amount of fuel, but it is based off the crankshaft position sensor, so it knows where the piston is traveling in the cylinder. Each injector has a spray "pattern" it does, and it sprays at certain angles, this angle is relative to the piston location, so it will try and spray the correct angle at the correct piston heigh to get the most fuel into the bowl. 6.4's are easy to get big power from with compounds and a common rail fuel setup. Their headbolts are much larger from the factory, but they're still plagued with the same crummy head design from the 6.0. They're almost identical heads.

Dad, you might want to try the easy exhaust stuff before you tear into the engine to try and elevate the lag and if needed a low power setting from a programmer. SCT like someone mentioned.

A stock 6.0 is just a laggy sumbeech. A tuned FICM is supposed to help throttle response like no ones business, and wouldn't really be anywhere near as risky as a programmer. I'd still run a street tune from an SCT without worry of gaskest if it was me.

Its been a few months since i last reprog. the PCM for him, he got bad fuel mileage when he drove to Missouri vs here in Louisiana.

The only thing i have a question about is the tuned ficm. Are you talking about the FICM being reprogrammed via SCT?

The next time he is out my way i will try and do all the tests i can on it. Im going to eat w/ him tomorrow and i will have a chance to drive it and see how bad it is.

IIRC, dad told me the truck starts to take off around 8-10mph, which is still better than a stock 6.4
