Hi Steve, I was wondering where you imbedded the string …
inside the bolt holes, outside the bolt holes or weaved in and out around the
bolt holes in an “S” or snake pattern? I redid my oil pan with
Ultra-grey but no string; however, if I ever take it all apart again I’d
consider your method.

All,
For what it is worth, I had a
slow oil leak between the oil pan or the block and the mounting plate the first
time I assembled it in spite of cleaning the surfaces well. The second
time I put things together, after cleaning all the mating surfaces several
times with brake cleaner, I embedded a light cotton string in the Ultra-Grey on
both sides of the mounting plate. This allowed me to tighten the oil pan
bolts without squeezing out all the sealant from the joint. This would be
somewhat similar to the use of a silk thread between the case halves on a
conventional aircraft engine. I realize that this is a limited data
set (one instance) but at least I don’t have oil leaks in this area so
far.
