how involved is such a job ?

 

I have done a little investigating myself since my driver's side mount let go. It doesn't seem like this is too complicated of a job. From what I have been told you need to undo the two large bolts, jack the engine and trans up ~3 inches until it hits the tunnelthen remove the old mounts. Don't jack on the oil pan and dent it... Then install the new ones. I was told that it may be a little tricky getting the engine back down once the new mounts are on. One person suggested having a steel bar for prying available. Estimates were from 1 to 3 hours I guess depending how fast you work and how much of a pia it is to get the engine back down. The big downer is the cost of the mounts themselves :-( I will probably go with the rotorsports racing rebuilds. Good luck.

 

It isn't that bad of job at all. If you have an engine hoist loosen the single nut that holds the mount to the engine cradle. Lift engine as far as you can using hoist and factory lifting hooks, remove old mounts, clean everything like crazy, brake cleaners work well. Clean off all the old sealant on the bolts.

Put sealant on the bolts and the surface of the motor mount that mates to the engine. Reinstall bolts. Don't glob too much sealant on the end of the bolt, the holes they fit in are blind, sealant isn't compressable, you can break the rear housing. This isn't very likely though.

You left out one important thing - Drain the oil before you start. Well actually two - Clean out the holes in the oil pan very well use a degreaser, reinstall new bolts with RTF sealant and wait for a few hours before filling oil back up.

I was searching for something else and noticed a step bye step on this subject with some photo's. It talks about the oil pan and motor mounts Give it a try.
