crankcase vent valve .. and there is even a newer one that replaces the mentioned
i looked at my invoice, no crankcase vent valve was changed out.
the latest: just got off phone with SA, Oil Separators backordered til at least middle of July, likely longer than that . . .

Noticed some oil on my garage floor. Looked under and definitely has some oil residue on the covers/area where transmission would meet the block.
I have not had it diagnosed yet, however after reading all this, i'm about 99% sure it's a RMS leak.
So add the G Wagon to the list, and there is a thread over there as well.
Quick question for those with the problem, not that I plan to wait very long, but is there anything to worry about if I can't get it repaired ASAP? Am I able to drive it still for a week or 2 until i'm physically able to have it checked out and repaired?...other than, of course the drops of oil in my garage.
I just don't want to be driving it and blow the RMS completely out and have oil everywhere and a blown motor.
I'll be demanding they replace the separators as well. Clearly they know this is an issue, maybe a class action lawsuit would get their attention.
Also, anyone have any luck regarding coverage the emissions warranty if the bumper to bumper is expired?? The emissions warranty is longer isnt it?




My process from seeing oils on the garage floor to diagnose to actual repairing it took nearly 3 months
