    With gas prices I have not driven the truck much lately but on the last trip I noticed the oil pressure is sky high with normal pressure lower then a "New motor 60lbs" Normallt about 40 these days but it up near 90?

    I wonder if an oil filter may be clogged or something along those lines?

    It's close enough to change so I'll possibly do that this weekend.

    Go see if your oil looks like chocolate milk. If so, you probably need a head gasket.

    Not likely, but possible.
    If it is a clogged filter, then you have to ask "what has clogged the filter"?? Unless you change that filter only about every 20,000 miles, the only reason for a clogged filter is that the engine is self-destructing. Even then, filters have bypass valves that open at some pre-determined pressure......although I don't know what that pressure would be for your filter.

    Mine went swimming once and my oil turned into a greasy white milkshake. If id only had a snorkel on the old Ford. We sort of missed the Kenny Ford and drove right into the fishing hole. :doh
    Entire hood under water.

    Dang...they put a bridge there now.

    Oil and filter change ASAP. Then maybe a oil added to break up gunk, like sea foam.
    If either of those two ideas work, change oil again just for good measures.

    I pour a little diesal, naptha etc in the oil almost every oil change to loosen any gunk prior to draining the oil. I change when the computer tells me so about 7,000 miles or so. No computer message as of yet but I should be close to the end.

    Could it be blow-by from worn piston/cylinder or stuck rings?
