Back of the block, down by the base of the distributor.

You can usually only get it from the top.

Re: oil pressure switch location 305 tpi

I have a 92 RS, if the oil pressure switch was going bad, I would see little or no oil pressure, correct? My oil pressure is always really high, usually around 45-60 psi, so I'm taking a guess that my oil pressure switch is working well?
