Help me identify this leak in the engine bay

deletedelete · 10-03-2009, 06:07 PM

I was looking around in the engine bay and noticed this small leak under the rubber hose next to the oil filter. What is that hose for and should I be worried? Thanks

Its right under the bend in that rubber hose.

get oil changed recently? Probably little oil from cap when it was off or during filling?

No I didnt. I changed the oil myself 4k miles ago and have cleaned the engine bay many times since then.

Anybody know what hose that is?

Over 100 people have read this thread and not one knows what the rubber hose is for? Come on guys. Im nervous here.

lol here's my guess....
It looks like the cable that connects to your oil pressure switch...

Oil pressure switch. Thanks. Now I just have to figure out why its leaking and what do to about it.

Clean it again and see if it comes back. That does not seem like much of a leak.

+1 ...from the pic it appears to be just a spot. if it were a leak i'd assume there'd be a trail.

There's no fluid in that cable. If you want to do it yourself, unplug the cable, remove the oil pressure switch and replace the O ring.
Better yet just take it to the dealer.

I agree with you.
That is the oil pressure switch so if were to leak, it would seem like it would be leaking bad.

id guess more than likely whatever you cleaned the bay with some got left under that connector...
