    It sounds to me like worn bearings. Clearances are too wide to maintain pressure. Sluggish engine: Have you checked compression?

    i haven't checked the compresson yet, but i'm wondering if the oil has lost its
    vescosity? The oil looks really old and dirt, engine oil pressure is good cold,
    But goes down as it worms up. I'm going to try an oil change and see if that helps it
    if it is the bearings then i guess i just spent $1200 for a parts truck.
    thanks glenn

    Low oil pressure is often caused by worn cam bearings. And it is typical for the oil pressure to drop when the truck warms up even though the viscosity increases.

    I CHANGED THE OIL & FILTER - NO CHANGE, STILL "0" LBS AT IDLE
    AND 20LBS AT 55MPH. STEP ON IT HARD AND YOU CAN REALLY HEAR
    THE RATTLE.....I NOW THINK YOUR RIGHT,,,,,THE ENGINE IS "KISSED"
    THANKS FOR ALL YOUR HELP.....GLENN
