Hi Kats,
I am glad that my experience with a car originally purchased new on 3/25/71 helped confirm the reasons
a redesign of the oil pressure gage/sender combination was needed. I had used the 90psi/6kg combination
with the good results that you describe, but I needed to use the 140psi/10kg combination to retain the originality
of my series 1 car. During periodic maintenance, my mechanic, who has worked on these car since the mid
1970s, confirms my oil pressure with a direct reading gage knowing that this was a problem from the start.
It also, as you say, gives me peace of mind.
Sorry, I am no help when talking about S20 engines in Z432 cars, but wish I had this Z432 problem. ?✈️
