Re: '77 MGB engine question

 On the clanging MGB engine with no cylinder specific symptoms:
 Might be the thrust washers on the crank. If idle speed drops
significantly when clutch is engaged, this is almost sure to be
the problem. Cranks are expensive, the washers are cheap. You
can also tell by prying outward on the damper/pulley with a
large screwdriver. There should be no visible endfloat.
 Unfortunately, you have to pull the pan to check for sure.
