Title: Low oil pressure on 4104 671
Post by: JT4104 on June 11, 2006, 07:00:38 AM

My 671 as of late has lost oil pressure after warming up to where it is only showing 5-6 lbs pressure on idle.

When I start it, it shows 40 psi on idle, 60-70 psi on high rpm.

When harmed up, even on high rpm's it won't go above 30 psi and my dash meter shows no pressure (although the oil guage on the engine shows 5-6 psi).

Using 40 weight shell rotella, changed the oil and filter but same problem.

Time for a new oil pump? Any suggestions would be appreciated.
