PU loses oil pressue on cold starts. Mechanics have replaced the oil pump, oil cooler gasket, tube has been tested, gasket between the pump and the pick up tube has been replaced and various other things one. No one can seem to figure this out and we are getting frustrated. All this is very costly and we wonder if we will be totally broke before the cause is found.

    hard to give some info on this without actually seeing it. all the basics have been done, assuming correctly. did they check the mains and rods for clearances??

    an engine shop is someone you should discuss this problem.

    wish i could be more helpfull.
