you have a large oil leak hitting the mount, thats what helped kill it, oil eats rubber. find and fix that leak or you'll be doing the mount again next year.
my oil pan was leaking on the mount, this is the one i took out soon after i got my car.
this is what was left of the mount in the mounts bucket where it sits in the frame.
it was dead a year or so later, cause the oil leak never stopped.
the year old or so replacement and the solid one i made. i also coated the top of the mount with polyurethane to keep the oil off the top of the mount.
