Dunno about "sealant", but I'd at least make sure they've got a smear of
engine oil on them.

When I did mine I did use Blue Hylomar, but then again I used Hylomar
*everywhere* (Around all of the ports in the valley) on that one.

Engine ran a lot better afterwards though.

One thought that occurs is that those end seals are sided - they
*almost* fit the other way round, as I discovered to my cost after
three hours refitting the top of the block (yeah - I was doing it in a
bad place with the hail beating down on me).

Let us know how you get on - I've more or less decided that my next
project is going to be acquiring a Disco rolling shell and using the
3.5V8 and 4 speed (LT95??) box I've got sitting rotting elsewhere to
build myself a nice rorty car with all the LPG and petrol hybridisation
I can do (Sill tanks, wing tanks, yada yada). The engine's going to
want seriously rebuilt though.

P.

I used blue hylomar, I used it on the valley gasket as well though. It
doesn't appear to have leaked.

As other have noted, a smear of blue Hylomar is a good idea.
