Sorry for making a new thread as I could find anything with my exact problem,So I’ve recently purchased this ‘11 G37xs Sedan in December and it’s been great, the engine as always been dirty other than the previous owner doing a quick detail of everything up top, any way I’m trying to find out what could be causing my engine to be this grimey on the driver side (photo/videos attached) I have no leaks underneath and my skid plate is dry and I changed my oil in December and have no oil consumption (meaning I haven’t moved on the dipstick) yet as I’m still under 2k miles with this oil, also on the passenger side it looks like it is sweating oil as well but nothing serious like the other side. TIA Right side Driver side by front/timing cover About half a foot under oil filler About half a foot under oil filler neck Passenger side Passenger side
VC gasket, quite possible that this leak weakened the silicone that seals the timing cover over time.
You'll need to clean all of that first and monitor if you want to diagnose the true fault.
Leaks by the ledge of the heads on the side are for sure VC gasket. This leak can look like a timing cover leak if left alone to continue.
Clean clean clean, paper towels on the areas of question, inspect the paper towels in a day to determine which ones are soiled the most. This will show you where the leak is.

How would one go about cleaning that far in? The timing cover should be easy to clean up. Edit forgot to mention , yeah it looks like it hasn’t been cleaned that deep before just up top which looks pretty good if you ask me, so it’s possible it seeped down on the TC

Depending on how mechanically savvy you are the easiest thing you can do for more space is to remove both airboxes. This will give you enough space to blast the timing cover area.
Make sure engine is cold, bring a few brushes, tooth brushes work great, rinse and then blow dry if you can to avoid staining/rusting.

I’m mechanically inclined enough to remove the air boxes, would I use a hose to rinse or just a water cup or something and cover up alternator, disconnect battery etc like that? I have brushes from a kit I ordered awhile back and wire brushes for hard gunk

Get you a bottle of this
Some tooth brushes and another spray bottle with hot water. Spray the Dawn and let it soak for a minute, start scrubbing then use the water bottle for spot cleaning. Once satisfied with the job, blow dry if possible. It will help differentiate between what you missed vs a recurrent leak.
This stuff works amazing so focus on the heavy parts because you're going to want to do the WHOLE bay.
It's insanely efficient for leaking oils/dirt and cleans plastics like plastic dishes. If you blow dry you minimize the hard water spots and will look even better.
Good luck.
