Good point - I neglected heat soak at idle after load... be easy to thread a fitting into the adjacent pressure port & check flow at idle, to make sure it isn't the oil pump or pressure regulator.

 

does anyone no what the proper oil press. should be? and bout how much a new pump is ?

 

5010965AA is the oil pump number (or should be) with a retail of around $330.00 should cost you between $180-225. The oil pressure regulator opens at 60 PSI. The first step would be to check oil pressure at the filter head where the line comes out. Oil pump failures are somewhat rare. It will cause pump failure. Have you recently changed your filter?

 

changed the oil about 1000 miles before break down

 

What type of filter. These symptoms are similar to those found in the failures seen in the early fram filters!

I only run purolator or mopar! Amsoil and AFE also make some good filters!
