Truck is an 04 250 FX4 ccsb 6.0
approx 160,000 miles
blew the heads at 90,000 and were supposedly redone then. Dude said he used ARP studs but lied... New oil cooler and a 06 EGR installed then
10/11 140,000 miles the FICM was bad and 3 injectors. Replaced all 8 injectors and FICM at Powerstroke specialty. I know I know you dont have to say it
Truck ran great for a while... it is just my weekend truck anyway
151,000 miles the turbo went. Installed a new powermax as well as new boots for cooler pipes. Flushed coolant,new water pump and thermostat.
About 7 weeks ago I got tired of the bad milage so I removed the Banks six gun and saw Jay at PHP to get a SCT X4 tuner, Insight CTS for gauges, and a FICM tune. Am still waiting for my custom tunes.....
Was like a new truck again!! The milage went back up to 18 mpg from the 14 I had been getting and it was fun to drive again.
Was going to head from Atlanta to Pigeon Forge friday so I checked everything out and the fluids were good and then decided to go ahead and install one of the pre loaded SCT tunes. Put the performance tune on it and did a quick drive. Ran good and less smoke than I had before.
Now to the trouble...
Truck ran good at 70mph all the way to Cherokee NC at normal temps 180 or so. The oil stayed within 5-8 degrees of coolant. Once I hit traffic in town the coolant spiked up to 230. It kept fluctuating from 190 to 230 going up the smoky mountains. Once we got to Pigeon forge we staopped and let it cool for bout 1 1/2 hrs and added 1 gal of distilled water to degas bottle. Showed no signs of puking and has about a 1 yr old Ford cap.
Continued to stay about 190-200 degrees that day around town.
Left early the next morning and made it home with coolant max at 196 going up mountain and leveled out at 185 most of trip.
Looked today and no coolant in bottle at all now and can see residue under the truck all the way back to the trans plate. Do not see a positive area of leaking anywhere but the back driver side head is wet and the front is dry.
Sorry for the long post just wanted to give as much info as I could.
What would you do?
Thanks for any help you can give
