My 280 oil pressure gauge I feel is going. It reads anywhere from 60-0. It usaully drops on accerleration then picks back up. I have also noticed it drops to zero for no reason at all. All the other gauges are reading perfect. Water temp 180-190. The motor sounds fine. So I am guessing oil gauge. does that sound about right?

It's almost always the oil pressure sending unit that has gone bad when this happens. The unit is mounted on the engine just forward of the oil filter. A new unit costs about $30, and should fix the gauge problem.

 

I think it's a common problem for all years. When I replaced mine ('71 240), Kyle from StrictlyZ recommended the Roadster unit as it reads more accurately than the Z unit.

 

if you cannot be stuffed spending the $30 or so bucks, or need to wait a week or 2 before buying./..

just get a steel brush, and clean the connection points of where it connects to the wires, and see how that helps, i did that, and i can now sometimes read what pressure i got, just at idle and all that it drops to below 0... hehe

Will the sending unit out of a 79ZX work in a 78Z?
