Just a comment, take it for what it's worth. The aircraft engine shop where
I have my work done has an excellent reputation. Not just good, or better,
but excellent! One thing they will *not* allow in their shop is RTV. Not
ever. If RTV is discovered on or in a customer's engine, work halts until a
complete inspection of the engine is completed and all traces of RTV are
removed. If this means a major teardown, so be it.

I think they are correct. RTV squeezes out of the joint both in and out.
Inside it will easily come free and circulate throughout the oil or cooling
system and may plug up passages. If you are lucky, it hits a filter first
and gets trapped. If not, you can lose an engine.

Each to their own. RTV is designed specifically to not do that when
used properly. Some types are not supposed to be used where contact
with fuel may occur. Others are formulated for hot engine parts. Use
the wrong type for your application and I guess it might fail in this
use.

My information is that some homebuilders have assembled entire engines
using only RTV for such things as timing chain cover gaskets, water
pump gaskets and oil pan gaskets, without any problems.
