Hi James , top marks to you mate going to the trouble of checking with plastiguage, I’m sure 99percent wouldn’t.. I’ve today been round all local autos spares, not one of them even heard of it , never mind what it’s used for.... Having established I’ve got stock crank and only the one shell available, still what is the ideal measurements outcome we are looking for , regarding plastiguage on these bmw crank to bearing face measurements, Eg 0.03 0.02 mm, Do bmw have a recommendation. ???.... sort of irrelevant I know as only one shell available , Any input also welcomed anybody
