Engine oil leak possibilities
 

I have an 06 3.0 and a new oil leak. I know very little about these engines and what the common leaks are. Can anyone tell from the pictures what may be leaking? The location is low on the drivers side.

Oil filter housing gasket.

It's about a 4 hour job, not too hard if you read up on it before you tackle it.

You don't mean the o ring at the top of the filter right? It looks dry around the filter area as far as I can tell.

No, the gasket underneath the oil filter housing.

You have to remove the alternator and a few other things to access it. Takes about 4 hours if you know your way around the 3L engine. It's not a hard job by any means.

Here is a good DIY on the OFHG.

OK thanks. Kinda strange it is related to coolant housing.

If you're doing the OFHG I would inspect CCV at the same time as well as the PS reservoir for leaks or cracks.

5 dollar part, 4 hours of work

OK, I assume CCV is crank case valve? How much is that? Maybe I should order that at the same time as the gasket.

Ditto that. OFHG, CCV, and PS lines/reservoir were all 'age' related leaks fixed in mine by the selling dealer pre-purchase in October 2013 [2/06 birthdate]
