rear main seal leak

According to my book for engines up to number #8S66782 its a 39 hour job and for engines number #8S66783 and up its a 10 hour job, hope you have the later engine as the transmission and flywheel has to be removed to get to this

That's because there isn't a very simple answer. That's generally a pretty major job. You will need a repair manual: http://bit.ly/mitchell_repair_manuals_online But you may benefit from seeking assistance from a professional.

A rear main seal can be a lot of work because its where the engine meets the trans. You need a detailed guide to do this that is why nobody can give you an easy answer.

on my 2000 E 4matic I have had estimated from $2,200 MB dealer to $655 in Broklyn NY. Have not gone anything yet
