    maybe the rocker and high mileage; I don't know how this camshaft is spinning, the technician said the wearing is on the back of the cam ,not the pushing side and this is happens when jake brake is excessively used;

    1 possible symptom is if your coolant smells like diesel.

    I had the cups problem 4 times, and every time the first symptom was hard starting, long cranking, losing prime fuel pressure, when the cups are leaking air, the diesel drains back to tank, I used manual prime pump also; but after awhile are leaking worst losing compression and power , I ignored once but lost power got towed ;
    maybe the head gasket is leaking, I had this problem with my last truck;
    the ERG coolers are well made on this motor, mine is still original; but some friends of mine changed it 2-3 times, and need to pressure check it to find leaks; The compressor gasket can also leak , the water pump and the coolant container level sensor, but this 2 are visible;

    It is very common for the cup bore in the head to be bad. If the cups move around in the head they will not seat properly.

    So the head must be replaced to permanently fix this problem

    Something else to consider is, fuel filter quality on the Volvo is sub standard for the injection pressures used.

    The stock filter is only 5um and not absolute rating. None of the aftermarket filters are any better either.

    One thing I have done is started using the 7um davco filter to catch a little more particulates before they get to the crap engine mounted filter.

    Anyways.....the pressure of these injectors requires considerable force applied to the injectors. This force pushes the injector up/down within the cup as a flexing. Eventually the deal at the injector tip or the seal to the head fails from the flexing.

    The steel cups flex far less than brass....but don't totally fix the problem.
