main and rod Bearings

[BlitZ]

OK ...
Ive research like for the past 2 days..

For main bearings i use the Block letters and crank numbers
for rod bearings i use the crank letters and rod numbers


That means i would have like 1 color per complete bearing? however from factory they are mismatched?


eg... my piston 1 rod bearing is green and rod cap bearing is brown..

Doesnt this jsut put the whole helm concept out of wack? what am i doing wrong?
