Made more progress today.

Installed the JDM underpanels after changing my transmission and differential fluid with fresh Millers CRX 75w90 NT gear oil

When pulling my original drivers side coils I found the source of my slow oil leak. It is not leaking from the cam carrier seal as I originally thought. It's coming from what looks to be the hole for the coil bolt and/or the coil/plug tunnel. I'm not sure if my eyes are deceiving me since it's difficult to see in there at all without an inspection mirror but the tunnel felt dry and the only oil I could find that was collecting at the bottom of the coil looked like it was originating at the threaded hole for the 10mm bolt securing the coil to the block. Very bizarre.

Plug tunnel appears to be dry, but I could be wrong since it's difficult to see.

Anyways I installed two new 652 coils on the driver's side (from below) and will keep these two original coils as spares since they still work fine and don't throw codes (yet).

I was going to install the race splitter but I discovered that I'm missing some hardware. @FT-86 SpeedFactory are taking good care of me and already sent it to me in the mail today. Thanks again Yo.

I also decided not to keep the Moroso oil pan baffle. I'm not sure it would be worth installing since the pan is adhered to the block and won't come off without prying it and inevitably bending it and have to flatten it back. I chatted with @Reaper about this and after agreeing that the factory baffle is sufficient and I don't see much benefit to the extra baffling since the oil level is already above the top of the pan in the FA20. I also haven't heard of anyone having issues with the pan itself not holding oil in it.

We agreed that I should instead be considering an oil accumulator (Accusump) to keep pressure and lubrication under high lateral loads before bothering with a baffle for the pan. Right now with 245 street tires I don't think it's an issue that needs to be immediately addressed. Should I go wider and stickier then maybe I will look into it more seriously.

Might go ahead and change the oil this weekend and do the drilling and bracketry installation for the splitter so I can get everything back together and ready for the rest of the hardware to get here.
