New oil Pressure switch, no oil pressure??

[Lex]

Ok , after making my CCAI this weekend (waiting for pics to develop), I replace my oil pressure switch because it was leaking oil. The problem I have now is... I replace my Oil Pressure Switch with a new one, and topped my oil, but I I have barely any oil pressure according to my gauge. its almost at the red mark. My leaking Oil pressure switch at least showed better oil pressure. Any thoughts on this??

plug the wire back onto the oil pressure switch.
It means one of 2 things, you have a bad switch and you should return it, or your oil pressure is really low (probably loose bearings).

Bhuff. Why I never thought to plug the wire back in....Now with sarcastic mode off, I have the wire plugged in. Ya it could be faulty. Bearings??? please go on

oil pumps don't go bad very often. They generally either work, or they don't. The biggest cause of low oil pressure is loose bearings. If you have large gaps between the bearings, then it takes a lot more oil flow to keep oil in them. The oil pump can't keep up with all that flow, and you end up with low oil pressure.
If you have access to an oil pressure gauge, you should probably check your pressure. I bet your problem is the sending unit though.

Turns out to be a faulty oil pressure switch. Works great now that i replaced it. Thanks for the info

switch = on/off

sensor = range of readings...
