[alfa] front covers

>>..the biggest issue on front covers would the alignment of the front
timing gear bushing in the cover, compared to the rear timing gear bushing
in the block.

I've mixed and matched blocks/covers (once) with no problems.

I'm about to mix and match a block and a cover again for various reasons. I'm
not worried about this alignment issue - reasoning goes like this....If the
bushing in the block is replaced then it must be reamed to size (see Alfa shop
manual), which I don't believe can be done with the cover in place - so the
reaming takes no account of the cover alignment. Same goes for replacing the
bush in the cover.

>>A secondary issue might be the bore for the front crank seal...
this is true and a little troubling - you do hear of blocks that have been
align-honed (line-honed?) having trouble with front crank seals - if the cover
isn't honed at the same time (and it's highly unlikely to be) then there would
be a mis-alignment. I'll let you know....
