I've come to the conclusion that my P38 4.6 has an oil pressure switch fault but I'd like to run the symptoms past the experts on here!

Intermittently and with no pattern the oil light comes on. When it is on there is no additional engine noise, no rattles nothing. Sounds exactly the same as with the oil light is off.

My question is there a failure that could result low oil pressure without any noises? Having heard what it sounds like when the oil pressure is low (after I changed the oil and filter it was on for a second or two) I'm 100% sure it doesn't sound like that when it's on. Have seen some cars that even though the oil light is on and pressure is low they don't really sound any different.

Thanks all

only way to be sure is to plumb in an oil pressure gauge, even if temporary..
and of course just change sensor..
