<VV> Rear Motor Mount Replacement

[Frank DuVal]

I remove drivetrains with a sheet of plywood on a floor jack under the 
oil pan. I don't think you will hurt it just lowering the rear to change 
the mount. Modern methods use an ATV jack, but I'm still a "balance the 
drivetrain on a single point jack" type of old school guy.

Yes, you can also put a small piece of wood between the floor jack and 
rear plate, but use caution, as this is a sloped surface and things can 
slip... Usually the bolt head keeps the wood stable.

When lifting under the oil pan, just use a wide sheet of wood to 
disperse the load. A point load in the center of the pan will leave a 
dent. A piece of wood the size of the oil pan will not dent it. Any load 
seen by the shrouds will be fine.

I am reluctant to support the engine by the oil pan with a block of wood for fear of damaging the oil pan and/or lower cooling shrouds.  Does anyone have any experience with supporting the rear of the engine with a block of wood and a floor jack under the metal plate assembly that is sandwiched between the rear engine housing and rear engine mounting bracket?  This plate is GM PN 3880558 and Item No. 0.027 in the Engine Group of GM Parts Catalog that Clark's sells.
