Good afternoon all. Anybody out there have experience with your high pressure fuel pump splitting literally in half? Causes? I had this happen. I have my high pressure fuel pump go out replaced it with a aftermarket CPX. No other aftermarket changes and fuel system or engine. Engine ran perfect had zero compression issues, always ran Schafer oil, has A bank's air intake I have put on it as well as have my hot and cold side changed when I bought the truck. Truck is fully deleted and has an ezlynk for tuning. Don't run a hot tune or anything crazy. Just towing versus Street tune. Basically After CPX was installed I was going down the road towing a empty trailer nothing heavy about 4K pounds all the sudden here are awful noise and motor shuts down. I never had metal in any of my oil changes or anything like that, but shop called me to tell me that motor was locked up. After another round of diagnostics on it they took the gear off the front of CPX and seen that it was split in half. So yet another set of fuel rails lines etc and the CPX reinstalled. Then they check the compression on the motor all the sudden I have compression problems and and being told I need a new motor. Awfully strange that the motor had zero problems before and zero compression issues. And never have metal in anything. I run a fuel treatment every tank to ensure water is being removed etc. Truck has only ever had Ford oil filters in it as well. And again as I previously stated never had drivability problems or loss of oil pressure either.
Any input would be appreciated. While I am not completely diesel dumb I am new at owning a diesel. There seems to be a conflict of opinion out there on what happened first the CPX splitting in half causing the motor problems or the motor causing the CPX problems. Just for the record as far as maintenance this truck is very well-maintenanced as I'm a business owner and use it for towing daily. I'm one of the only female owned outdoor construction companies and need to be able to rely on my vehicle. As a single female you could imagine that as I said I'm not completely diesel dumb but at the same time I'm not a mechanic either. Truck gets a fuel filter every other oil change, with oil changes at 5K and always recharge after cleaning Banks air filter. I have a Venturi reroute also... But it was done quite some time ago and truck ran perfectly fine up until this point. I've done other things to it like putting a master cylinder in it and new hydro pump, brakes but that's about it no major catastrophes until this.
