question on the crankshaft seal oil drip.. Is the oil leak pretty evident when you look at the bottom timing cover in that area from under the car?
I see couple of drips on the floor overnight from my car. Nothing to be concerned about yet, but I want to know how to diagnose it, easily.
Probably can't do the repairs myself and need to take it to the dealer/shop.
I had to clean the oil pan a few times with brake cleaner to identify the source.
A few times I thought the pan seal was leaking. Eventually I saw the clean stream of oil from the timing cover. I'd estimate I spent an hour over the course of a few days isolating the leak. It didn't help the leak had been going on so long.
I replaced the left wheel bearing and hub as an assembly. Nothing appeared wrong with the old assembly. I can only guess that the hub under a side load was shifting inside the bearing causing the pop.
Thanks for the documentation and photos. I recently bought an '08 RX400h, and although I understand the problem and what you did, I couldn't do it myself. Wish I could find a resourceful mechanic like you in my area! My son has done some work on cars and is an electrical engineer, so hopefully he could take a shot at something like this (?) So far, no problem with the hybrid battery, but I want to be prepared. I hope you are enjoying yours as much as I'm enjoying mine!
