Perhaps you have seen and/or responded to my previous
requests for clues to the infiltration of water into the
crankcase of our newly rebuilt SI 4.2 '67 OTS engine that
has yet to be resolved.
Since the original block (#7E9502-9) was not salvageable, I
have mated all its parts to a ‘newer’ one (#7E17784-9)
during its major, professionally done rebuild.
The current question is regarding the compatibility of those
parts (head, timing cover, oil pan, etc.) to the newer
(+8212) block.
I’m hoping for insights that will avoid the necessity to
pull the engine/transmission back out of our beautifully
refinished car.
Does anyone know or know how I source this kind of information?–

In reply to a message from BigBert sent Sun 22 May 2016:
A 7E block is for a 4.2 E type, so I would anticipate that it
is identical to the one you replaced.
That much water in your crankcase implies to me a failure of
the gasket between the timing cover and the front of the block.
If a generic gasket set has been used it may have contained
gaskets for later cars which may have been used in error.
It is always possible, I suppose, that you have a leak in the
head or one of the other ancillaries, but if those parts were
OK to start with then it’s unlikely that something new has
developed there.
It is possible to remove and replace the timing cover with the
engine in situ and I have done this myself. However it is more
difficult to ensure a good seal with the front crank seal, and
removing and replacing the cover may affect the seal between
the top of the cover and the head. Were it mine, I’d want it
done properly, with the engine out.
If the rebuild was ‘‘professionally done’’ then rectifying the
problem, including removal and replacement of the engine, is
the responsibility of whoever built it.–
