So i’m guessing it’s not under warranty still huh?
I would clean everything with brake cleaner and drive it for a day or two and check the same spot and see if it’s wet again.
If inside the bell housing is all wet with oil then it most likely needs a new rear main seal.
Good luck and please keep us posted.You really can’t make any assumptions here as I’ve seen some pretty strange oil leaks on the backs of Honda blocks. It’s true that the most likely culprit would be the rear main based on your description however it could be galley plugs or a block casting fault, the only way you’re going to know is to remove the transmission and flex plate and put your eyes on it to know for sure unfortunately.
Not sure if this could possibly be an issue but have you recently done a oil change using synthetic oil ? Sometimes that will cause some leaks that would not have occurred with the use of conventional oil. Perhaps Eric could address this as well.

Excellent point! If you switch to synthetic on a high mileage engine it’s not uncommon for just about every seal on the engine to start leaking.
Thanks for the inputs. I have been using synthetic for the 20,000 miles I’ve put on the pilot. I called Honda Corp with my issue, since it is out of warranty, and they gave me a case #, with instructions to visit the dealership for evaluation-of course no promises of help. My question to you is, is there a Service Bulletin out there for this problem that I might use as leverage? T)
I did a quick search of TSBs for a 2008 Pilot. Refer to this link http://www.automd.com/recall-tsb/search/?m=Honda&mm=Pilot&y=2008
None of these however were related to oil leaks. If Honda does not come through with a fix you might want to change back to conventional oil. Monitor your oil leak for at least two oil changes before you go to the time and trouble to repair it out of your pocket.I would go ahead and switch back to conventional oil if your leaks are because of using synthetic. I would also recommend using Penzoil High Mileage with seal conditioners in.
Good luck and keep us posted.
You guys are the best!! I will try conventional oil before cracking it open, and thanks for the link.

Good luck and please keep us posted.It’s out as out can be. I will make some noise to Honda and the dealership, to press the issue of this failure being so early and most expensive. Just to be a thorn in their side- get my satisfaction I guess.
I have a 2002 V6 Accord that had about 110K miles when I started using synthetic oil and then a leak at the rear main seal appeared. Switched back to conventional oil and after about 8K mile the leak stopped. No more leaks in that area at 143K miles. I would just change oil when it’s time and monitor before you lay down $1200. I would be angry as well with 2008 car that leaked oil. But just give it time.
I doubt you’d get anywhere with Honda unless you were getting your vehicle serviced there. That said if you’ve been using synthetic switch back to regular oil of the correct viscosity which I’m not sure if you run 5W30 or 5W20 in that one, heck it might be 0W20, check the oil cap to be sure what lubricant to use.

I’m shooting in dark going through Honda for help; just pissed that a 68,000 mile Pilot has this kind of problem, which could cost over $1200 to permanently fix; however, I will take your advise and change to conventional oil. Thanks and I will keep you guys informed .
I wouldn’t be too mad at Honda, if it turns out that it was the synthetic oil that caused the issue then it’s really not their fault.
