Mitch, thanks for the detailed response on this sealing block! Did you
replace the wood? wedges?

Hey Jim,
The sealing block was a continuing source of frustration for me as well. There
is an early & late version of the block, both fit but the later is slightly
redesigned & reinforced (not much improved). There are a few reasons for leaks
in this area. The aluminum material used was very soft and has a total of 7
bolts going through it. It is torque in two directions, sealing the timing
cover, oil pan & block. There are 3 bolts in the front for the timing cover
that are short. Very often the two outer bolts are accidentally replaced with
longer bolts , when you tighten these down they end up hitting the two sealing
block mounting bolts (the ones going up in to the block) & stripping. These
two are critical in length This is the case for all of the bolts that screw
directly in to the sealing block itself. The aluminum is soft and strips
easily. In addition the voids on either side of the block are sealed with WOOD
wedges.
After lots of back time under the car repeating the repair I finally used a
thread repair called Keenserts
http://www.ondrives.com/products.asp?recnumber=437 . Between these, the proper
bolts, Hylomer sealant and careful reassembly I have not seen a drip in 4
years from this spot.
If you have a bentley manual , page 133 shows the part & assembly. If you need
more info let me know.
