I think I've seen this discussed previously, but can the oil pressure switches leak right through the switch? I'm gearing up for some work on my '94 Legacy. The engine has quite a bit of oil over it and I thought originally it was the valve cover gaskets.

 

But when looking at it closer, it almost looks like it's coming from the oil pressure switch under the alternator. Like that little spade terminal where the wire connects, it is wet with oil as if the oil is coming out right through the switch. Does that happen to these switches? Thanks.

Yes, they can fail and leak.

Great, thanks for the info. Fortunately that part isn't too expensive I now see.

 

Say what do you think about this? http://www.subarupartsforyou.com/cp_partlistbymod.php?subcat=Switch%2C+Oil+Pressure

 

They have the same part # listed for every soob, even the SVX, except the one for the SVX is cheaper?

As far as i know, they are all the same for sure. If that's what you are questioning.

Thanks. It must just be their slip up, posting a lower price on the SVX when they are all the same part #. It's just something that caught my eye. A board member is hooking me up with a new genuine switch along with some other parts.
