Since all you have to do is put the head back on, I suppose someone might
advise you to leave it and run it until it becomes a grander problem.B That
wouldn't be my advice.B
If your friend has any intention of driving it, as opposed to trailering it
for show, fix it right, and right now.B If you're going to weld it, you have
to pull and strip the engine anyway, so why not source a good block somewhere
instead?B Given the wet liners, a strength of these cars is that the blocks
are much easier to find than MG's and others (at least it would seem).B Too,
they're typically inexpensive...or not a lot more than having welding done.B
In fact, mine was free from a Lister who had a spare, since my original block
had cracks in the web underneath the cylinders.B All I had to do was drive to
Connecticut to get it, a couple of hours away.
Just my two cents...and the price of copper is down!
