So much work on my new van, belts, front oil seals and it repays me with a nice oil leak. Leaving several drops after I park running down the left bar next to the oil pan. Remind me why I got another L300? :)

It seems to be dripping down from the AC compressor. I park on a slight incline (nose up) and after running it a small drop will start to form on the AC mounting bracket to engine.

Keep in mind I changed the crankshaft, and balancer seals 100km ago so I hope to narrow that out.

I'm wondering if its the front lower case engine gasket? I've arrowed it in red. Anyone have any experience with that culprit?

I fully expect to tear down the front of my engine again quite soon. Practice makes perfect I guess.

Another pic after I took off the belts and front covers. You can see the mess in the bottom right. The empty holes are for the AC tensioner bracket. Orange permatex from a prior owner is surrounding the entire oil pan.

The front shaft seals are dry so I can narrow that out. I'm also not entirely convinced its coming from my oil pan....

There's a side cover with gasket about half way up on the left side that could be leaking.
 
Hey Steven for sure but that area is dry so I've narrowed it out, after taking out the AC compressor mount I've pretty much determined that its the front upper case gasket.
