Oill pressure guage drops when warm on L body

[turbospirites]

I have a 1991 Dodge Shadow ES 2.5L turbo the car runs great and the problem is that the oil pressure gauge drops to zero when it's warmed up. Opened the valve cover and it's oiling fine no knocks or anything should I just get a manual gauge and find out and what are the thread size to put a aftermarket gauge on it/

they have black ones too, it attaches to where the plug is in the block that feeds turbo with oil...

Thread size is 1/8 pipe thread.

Just get a cheap mechanical gauge to check it from Walmart, Pepboy's etc.
