My 02 MCS has been leaking oil for sometime now and has become progressively worse, the leak is passenger side and fairly heavy now, approximately 7-10 drops an hour. I have stopped driving it as to avoid damage. I'm getting ready to order the replacement crank seal for it, as I am pretty certain this is the source. Any thing else I should replace whilst I have things apart? Thanks!

 

Since you have it off, replace the crank pulley, its gonna fail sooner or later.
