had oil changed and they put 10w30 i was using sae30 hd now oil pressure fluctuates and runs low ,i cann't seem to locate the oil pressure switch on front of motor .i would appreciate any suggestions or advice thanx.

I know on the windsor V8 it is on the driver's side towards the front, close to the mechanical fuel pump. I never worked a Cleveland unit. You may have to pull away both the power steering pump and the fuel pump to get to the oil pressure sensor. It requires a special 8 sided socket, known these days as an "oxygen sensor" socket, that has and extra cut for the non-removable oxygen sensor wire. I got my socket at Big Lots. The sensor screws in a regular 1/4 fpt pipe fitting, you can tap in a mechanical gage temporarily if you want to confirm your pressure with something calibrated. Be sure, putting the fuel pump back, to put the top in before the bottom and then tip it down to let the threads engage the holes, to make sure the rocker engages the cam properly and doesn't get bent.

thanks alot for the info.i will check it out after it warms up outside.pretty cold here for south ms.
