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

PS, please fill out your vehicle information in your profile.

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?
