    Yep @Bob BMW; I'm intimately familiar with the havoc inflicted by that little gremlin factory. I will ultimately bypass it all together, just haven't yet. The list goes on and on

    The rest I'll chalk up to resistance in the original wiring left after I replaced the worst of it.

    My owners manual actually SAYS that the oil pressure will be low at idle. So I'd say, "it depends"

    Oil pressure gauge settled in where you see it in the pic under idle at temp ~175

    This is from a 73 1110 SV392,( first pair is while warming up, 2nd pair after warm up) just replaced the SW oil pressure gauge plastic line with a copper line to the sending unit yesterday.[plastic line developed a leak? Say it isn't so..]

    Like most have said the stock gauges are more " warm fuzzy" than anything definitive.[​IMG][​IMG][​IMG][​IMG]

    Odd to see higher OP on the wet gauge with the hotter engine. Generally the opposite is the case which only stands to reason. Colder, thicker oil will register a higher pressure at a given engine speed than heated, thinner oil will at the same speed. Was this at @ 700 rpm idle speed in both cases?

    First set was while warming up, I don't have a rpm gauge, the second set was while on the highway at 50 mph

    Looking at the oem gauges pics again I might have them reversed

    For it to be more of an apples to apples comparison, the engine ought to be idling for both sets of pics.
