Another piece of the puzzle is that I ran non-desiel
rate oil for about 500-600 miles. Could that be
gumming it up?
Approved oil of the proper viscosity should cause the needle to peg when
the engine is started cold - and may remain pegged until the engine has
run for 5-15 minutes. Then the needle usually will drop to between 1 and
2 bar at hot warm idle. If oil viscosity becomes too high (because you
are using an unsuitable oil, oil additive or the oil is contaminated in
some way), the needle may read high. Simply change to an approved oil
type and viscosity. If oil pressure get too high (above about 6 bar)
there are relief valves in the filter housing and the pump housing that
will open and prevent any problem.
Only problem with running a non-diesel rated oil (now that fuel sulfur
has been reduced to less than 0.05%)) is that it will not handle soot as
well and will require changing somewhat sooner. Changed at 500-1000
miles, NO problem (if the viscosity rating was appropriate).
