Because the chances of CSand being spread thru-out the rest of the
casting, it sounds like it's a total write-off.
I used to try and wash out all the debris from engine and head
castings,..after grinding work had been done,...*and* it was a waste of
time. Once garbage had been allowed to spread thru-out the casting,..you
never get it all.[speaking for myself !]
Sure, the little allen keyed oil-drillings allowed force-gushing with
water,...you'd think it was all done ? Nay, after a 2nd strip-down
there was *always* some crap left in the crank oil-drillings, for example.
I had a differential failure in a '62 Morris Major. The hemisphere
cracked, allowing a heap of swarf to be generated and spread thru the
housing. I used a mirror and a magnet to try and remove the millions of
tiny cast-iron flecks thru out the banjoe-case. No go :-(. It caused the
early demise of the 2nd Diff-centre I fitted. You need to replace the
whole diff-assembley...[those were the days...shudder ]
