the idle speed on this m103 does not bother me normally, but now when it gets around 100 degrees,the oil pressure drops to one bar. most of the time it's 1.25 bar
so my question is what should idle be in drive?i get 500rpm most of the time, 1.25 bar oil pressure
when the pressure drops to 1 bar the idle is 480 rpm.
idle is smooth always
should the idle be higher?
hope this make sense
thank you
rich
