anybody experiencing problems with no oil pressure at idle - new rebuilt engine?

Has anybody else experienced problems with no oil pressure at idle after highway driving? What was the problem diagnosed. Pick up has been cleaned twice and screen cleaned as well. Any suggestions as dealer can't figure it out

i had the same problem with mine. I replaced the the oil pump. It is made out of aluminum which does not stand up to heat and wear as well as the old cast iron used in engines years ago. I would recommend taking it to a mechanic instead of doing it yourself. It's quite a pain.
