    I have my 2008, Ford 6.4 at the Ford garage. I took it in because it was puking coolant while towing my 5th wheel. Ford garage did the compression test and checked the computer to see if egr cooler. They said everything was fine with the egr cooler, but problem was a head gasket. Cab was lifted this past week and $1200 worth of ford parts were replaced. This was on the left side. Everything was put back together and cab re-attached. Service manager took truck out to test drive today and said he drove the truck 80 mpg and the truck was still leaking anti freeze. Right now they are waiting to hear from Ford to find out what else they can try?
    I asked him if it's not the egr cooler, what else could it be. I suggested maybe the gasket was pinched or installed improperly, but he did't think so. The garage has had the truck since last Wednesday and the parts came in this past Monday. Can anyone give me any ideas of what could be the problem. I'm starting to get really nervous about this garage???

    I am not at my local Ford garage. I'm 400 miles from home and driving a rental car.

    The truck has 109,000 miles on it. I've always had all required maintenance performed on it at my local ford garage. No tuners or anything like that on truck because I didn't want to screw with warranty. No warning lights or excessive temperatures shown while driving. Getting to be very frustrating and expensive.

    Are you still under warranty or is this out of pocket? I've had limited experience with service managers thankfully. One of them wasn't the greatest. I don't think he realized I knew more about cars than he did.

    No on the warranty. I'm like you on the service manager and the service advisor. I don't think they really know either. They have been told by Ford to drain all the oil and to pressure up the cooling system. If it leaks coolant, could be a cracked head or cracked block. This is coming from the service advisor? Now that scares the $hlt out of me$$$$. I really have a hard time believing that when I know how I have driven and pampered this truck. With 109,000 miles on the motor, why would anyone want to buy a Ford diesel if that's what happens. I don't want to get too excited because I haven't heard the results of their tests yet. I'm still believing an improperly installed head gasket???

    Here is some of the communications going on between Ford and the dealer mechanic:

    Mechanic: Once at operating temperature and under load vehicle loses coolant threw degas cap. I checked for codes, no codes, pressure tested, did not lose pressure, test drove under load with pressure gauge tapped into cooling system, highest reading 18psi on test drive, checked for combustion gasses in cooling system and gasses are present, checked egr valve for contamination, none present, no external leaks. Relative compression showed cylinder 2 & 8 down 4%, performed manual compression on passenger side #2 330psi, #4 340psi, #6 340psi, #8 320psi.

    Ford: With the presents of combustion in the cooling system, this can be caused by a leaking EGR cooler, a head gasket failure or by a cracked damaged cylinder head. We will first want to test the egr coolers for leaks. We will also want to inspect the egrt sensor on the top of the vertical EGR cooler for a steam cleaned appears. A steam cleaned appearance or liquid coolant in either area would suggest that we have and EGR cooler leak. If no leaks are found, this would indicate that we have a head or a head gasket failure.

    However, before continuing with any additional diagnostics for this concern we recommend performing a manual compression test on cylinders 1,3,5 & 7 to get a better understanding as to the state of the base engine. It is best practice to perform a manual compression test on all eight cylinders when a loss in relative compression is noted.

    This is recommended because the compression on the left bank is extremely low.If we find a 25psi variation or more between the highest and lowest compression reading all 8 cylinders, this would confirm that we have a base engine concern. In this scenario, the engine will need to be removed for disassembly and inspection to determine the root cause.

    Mechanic: checked egrt and even sensor, no steamed appearance found or evidence of coolant. I apologize the first compression reading I sent were for cylinders 1,3,5,& 7, number 2 was 300psi, 4 320psi, 6 340 psi, 8 300psi, removed passenger side head, found evidence or leakage on head gasket, straight edged mating surfaces no concern found, replaced head gasket, performed relative compression, 0% loss in all cylinders, test drove, coolant puking through degas at hard load again, checked relative compression again #2 and #8 down 5%, would removing and inspecting the head again be the next best step?


    Ford: If there is coolant punching out of the degas bottle after new head gaskets, and no evidence of coolant in the EGR system, this suggests there is a block concern present. This should be able to be confirmed by draining the oil from the engine, and pressure testing the cooling system. If coolant drips out of the drain plug, then there is a crack in the block, or faulty head gaskets. Since the head gaskets are new, then there is probably a crack in the block. If coolant drips out of the oil pan, then the heads should be removed and the block should be carefully inspected.

    If coolant does not drip out from the drain plug, then crank the engine over by hand a little bit at a time. Even until the engine has been rotated a full resolution if needed. Make sure that the cooling system is pressurized the whole time to insure accurate test results. If there is coolant dripping out the hole, then cylinders 2 & 8 should be carefully inspected for faults.

    If coolant does not drip out of the oil pan, then carefully inspect the EGR system components for leaks, especially the lower EGR cooler because that's where The coolant tends to collect or be prevalent. It's not suspect that this is the cause of the concern as seen by the compression results. It's suspect that there is a cylinder fault present and that's the reason for the low compression, and the gasses in the coolant.

    Side Note: Inspect the charged air cooler (CAC) for oil or other contamination that may be present. Cylinders 2 and 8 are affected the most by oil ingestion from the CAC and tend to be one of the more noticeable cylinders if there was oil ingestion causing cylinder failure. If there is oil in the CAC then the turbos should be inspected for oil leaks


    Results: After I discussed this with service advisor, I was informed the above tests were compled for the leakage from the drain plug and oil pan. No leakage of coolant was detected. They are now in the process of checking the lower EGR cooler. Won"t know the results until Monday.
    I hope this helps.

    Well, they have eliminated the lower EGR cooler, now just waiting to hear from Ford to see where they go from here?

    What kind of shaking? Engine or steering shakes? We do not play guessing games here.

    What is the latest on the black F250 truck?


    You have my attention what's up with the F250?
