[Healeys] Engine Block Filler for Healey Engine

[Larry Varley]

Hi Harold. Rather than doing this, if you have concerns, I would have the
block vacuum impregnated instead. In Australia it is a process from Loctite
and it can seal some major porosity. I used it successfully for many
aluminum castings in business that we made that were subject to over 100 PSI
air pressure, and it sealed all of them every time. Recently I had a Healey
alloy sump vacuum impregnated that was full of porosity and it sealed it
fine. I would think there will be people doing it in most countries. I would
get the block hot tank cleaned first.

Regards
