Does this look like an oil pan leak?

I'm trying to track down the source of the leaks shown in the photos. I recently replaced my OFHG, CCV, power steering lines (the three feeding from the reservoir and cooling lines), and VCG. I also replaced the o-ring for the oil filter. I was pretty sure that it was coming from the OFHG, so I redid everything and torqued it to make sure the top 4 bolts around the gasket were tightened before finishing up with the bottom 2. I didn't replace the vanos line except for the crush washers at the OFH.

I also had to go back and redo the VCG in order to replace a vacuum line. I cleaned everything up of oil and grime last weekend and checked for leaks today.

There was some oil spillage around the central jacking point hole on the plastic belly pan as well as on the underside of the oil pan. Also, I saw some minor oil collections on the top two areas in the honeycomb structure. It didn't look like there was any oil to the left of the area closer to the OFHG so I'm thinking it might not be coming from there.

It's really hard to tell what's happening at the front portion of the oil pan because of all the stuff in the way. It's not red so it's not steering fluid. Anyone know if the oil pan can show leaks at the spots I circled? I didn't have time to jack up the car to get photos w/o the belly pan in the way.

thanks

Oil won't travel upwards, so the leak in the first picture cannot be the oil pan gasket. Your pictures aren't great, but it really doesn't look like you have a leak to me?

Perhaps you should clean everything off and monitor it if you're worried about it.

The first photo was taken last week before the leaks. I didn't have my camera with me today. It just gives you an idea of where they are.

As for the oil deposits in the first photo, isn't the front part of the oil pan in the area of where those bolts are to the right?

I'm voting its your Oil Filter Housing Gasket if there is oil in picture #1.

The area to the left and top of the oil deposits shown in the first photo appeared to be dry. Why would an OFHG leak show up all the way to the right?
Is it possible that one of the connections to the new CVV is leaking? The car has about 165k on it if that means anything. I'm starting to think that maybe it's pointless to expect it not to have any oil leaks.

No, that's the motor mount. The CCV is in the general area, so that's not a bad guess. The oil pan runs along the bottom of the picture, you can see the bolts for it.

I'm wondering if maybe I didn't clean the guide tube well enough when replacing the CVV and it's causing an oil leak on the bottom of the oil pan. I didn't update the guide tube, just replaced the o-ring at the bottom. If I blow through the hose where it connects to the valve cover and I hear bubbling at the oil pan, does that mean everything is clear?
