  1. I got a 2018 f-350 6.7 with losing coolant 60 000km. Customer has come by 3 times to have coolant top up about 6 litres each time, good customer who takes care of his trucks.I have checked for external leaks and found none, oil level is not over full, trans oil looks red and is not over full, have pressure test with it running and found the cooling system holds a vacuum. Road tested with a pressure gauge and found when the truck is hot cooling system pressure spikes to around 25 psi, my gauge did go any higher so it may spike even higher. Took the egr cooler off today and pressure tested it, does not look clean from coolant and its holding pressure with the test gauge installed. Anyone out there run into anything like this ? Last thing I am going to do befor taking the heads off is pressure test it over night and check the glow plug holes for coolant, any input is appreciated.

  2. I have not been to ford school in a long time so I miss out on a lot of the rumours, one of the kids in my shop just came back from a class and he told me that the rumour is that ford will be putting cummins diesel in the super duty in 2021. It sounds like bs but just wondering if anyone else has heard anything like this. 

  3. Update

    I assembly the head and put air in cylinder #4 and found air good amount leaking from the intake valves and some out the bottom side of the piston. The insurance company did not want to chance it so they are putting in a long block with fuel system. Now just waiting for parts as most of them are back ordered with no promise date.  :banghead:

  4. I have a 2017 f-250 6.7 that was filled with def and ran till it quit. I performed a relative compression and found that #4 was low. I performed a manual compression test and found that #4 is at 100 psi and #2 is at 140 psi. The other two where both around 350 psi so I pulled the head off and inspected.  Being so low I hoped to find something. All pistons come over the deck the same amount, cylinder wall look good, piston tops don't look melted and I pull out #4 piston to have a look and don't see anything odd on the rings. I did find if you pour varsol on the face of the cylinder head you can see it leak into the intake and exhaust ports of the two cylinders and not on the other two. I don't think there is enough leakage to account 250 less psi so I am stumped as to where my lose could be. I did perform the manual compression test two different time just to be sure, even pulled the gear off the high pressure fuel pump just in case it was locking up. Have any of you had a 6.7 with base engine damage after being run on def ?

  5. I have a 2017 f250 that came in for incorrect level stuck at 3/4. So I topped up the def and performed a re fill activation. Now the truck reads empty. I have no codes koeo koer and no cmdtc's. So now i start going through the pinpoint test and get to rj9 and get lost. I can't seem to find where the reductant dosage control module is and can't find the circuits in the wiring diagram that they want me to tie together. Can anyone shed some light on this, is the reductant dosage control module the def heater/sender and they have just change the name in that pinpoint test? I still can't find the rdl1 2 3 pins though.
