[Healeys] AH100 Mean bearing caps needed

[John Harper]

I don't have any spare caps but a colleague had the same problem. I had 
two old but recoverable blocks without caps and he had caps from two 
frost damaged blocks. The replacement caps had to be line bored as you 
say but in order to not disturb the accuracy of the crankshaft location 
his machinist first skimmed about 0.010" off each of the caps where they 
mate with the block. These were then fitted and the line boring was 
carried out in such a way as the cutter only 'kissed' the block but cut 
into the caps. Just to be on the safe side an extra small section of 
gasket material was added to the front and rear caps where the sump 
gasket would otherwise be possibly a little lacking in pressure.
