B58 engine oil leak (rear main seal)

[hoohoohama]

The check engine light I was told was due to the computer glitch as it has to convert from liters to gallons. The system flash will fix this when it comes at the end of August. The dealer cleaned the oil around the starter and told me to drive it another week so they can pinpoint where it's coming from. It looks to be a rear main seal weep. We'll see. The problem is no parts availability.

Thank you for the updates, IMO, I doubt if it is actually the rear main seal, as in my case, I was told the same thing and waited for weeks for replacement parts, and then was told it wasn’t the rear main seal and it was from some sort of lubricant being melted after engine got hot.

So the theory is that you will only see this oil drop if the engine is hot, hence if you clean the oil drop near the starter after the engine has cooled down and leave your vehicle overnight, you shouldn’t see it next morning. but it may show up again after you drive the vehicle for a while.

Thanks for the insight. The dealer cleaned it and told me to drive it for a week. In all honestly, I've been so busy I haven't had the time to crawl under to see if the leak is still there. Dealer called this morning to check on it. I'll look at it some time today.

Having the same issue I think. Seeing some small oil leaks on what I think is the base of the transfer case. Also seeing the black cap on the front left under the hood having some small overflow. I’ve read that is intentional, but I am concerned about the apparent oil leaks. 1000 miles on the Trialmaster. The AC condensation drain forward of all of this is also dripping a lot making it hard to understand if that is contributing to what I think is an oil leak near the transfer case. Transfer case temp is fine. Closest dealer is 5 hours away. Any suggestions?

Talked to the dealer service and the black cap under the hood is power steering and that’s designed to self vent. The apparent oil leak near the transfer case may actually be the AC condensation drain which he said is known issue for being excessive in the water drain which may be condensation floating back to the transfer case and collecting oil which is appearing to drip. He advised me to wipe it all down and keep an eye on it. If anyone else has experience with this issue let me know.
