Gday All,
As of last night my oil pressure guage will read normal and then randomly and independent of rpm, will drop to almost 0. When the engine rpm is increased the pressure will rise but not as much as normal. It is reduced by about half of the normal readings at any given rpm.
I am wondering whether it is a voltage issue or guage issue or worst of all, an actual oil pressure problem.
Any insight into this problem is appreciated. Car is a 1989 GT-R.
Cheers,
Ben.
