haha oil pressure
 

so you know how the stock oil gauge is just not accurate well i went and bought a mechanical one and took like 2 hrs to hook up i finnally fouind a bolt on the side of the block where it looked like oil passed through so i hooked the adpater up to it and i think it works am i rihgt?

You might be getting a different reading because oil pressure varies throughout the engine. You should replace the stock oil pressure sending unit with the gauge you bought, compare your readings, and use that oil passage for an oil temp gauge.
