loosing oil from a sensor??

With my 94 saturn SL1, I've noticed that the back of the engine is
always wet. When I change the oil I wipe it good and not long after it's wet
again. I was checking and noticed that there is some kind of sensor in the
back of the block. Now I know that it's coming from not the valve cover
gasket and it's not the head gasket. There it's dry. It seems to be
underneath these. That's why I think it might be this sensor. Anyone have
this happen to them??

It maybe the oil pressure switch, just below the intake manifold. If it is
like my 2000 SL2, it would be metric thread and use a sealing washer [ not
crush ring ]. You should be able to just tighten it, IF you can get a
wrench to it without removing the intake manifold.

 

Sensors do indeed spring leaks. On my minivan, the oil pressure switch
started to leak in the area between the metal body and the plastic end with
the connector. With 90K miles on it, couldn't complain. New part cost in the
neighborhood of $20. Seems that the old sensor had an O-ring between the
metal and plastic pieces that developed a crack.

tks. I'll try to tighten it this week end. Let you know how I make out
begining of week....

Talking about sensors, if you ever have a heavy fuel consumption in cold
weather I found out that the air temperature sensor is a must change. Just a
little note...

The oil pressure sensor in my 95 SW1 went bad a couple of months ago.
Dropped 2 quarts in 35 miles bad. Lucky for me that I check the oil every
day. It was easy to replace from under the car. Strange thing was that no
auto parts stores had the sensor in stock on the weekend when I was fixing
it. Got a new one at NAPA for $14, but it took them a day to get it.

Hello there, Well I had a pretty good weekend. And guess what, I was
wrong!!! 1000000 apologies..... I ewnet down to my brother in law over thte
week end. He's better equiped than I. We raised the car and had a real good
check underneath. Cleaned it good and found out that there was an
accumulation of oil underneath the valve cover. So I guess it was a little
higher than I thought. So that's where the problems lies.... Thanks to all
