In the midst of a clutch replacement and am doing the IMS, RMS, etc. It's a 99 Box with about 42K miles. I purchased it about 18 mos ago with 39K miles on it. Has been running great so far.
I pulled the trans and flywheel. The engine has a lot of grime on the engine/trans underside and inside the trans bell housing. I expected to see obvious leaking from the RMS or IMS seal. See photos of the bell housing, and of the IMS/RMS. Where do you think the leak is originating from that's causing all the grimy buildup?
