A replacement now can be of the same weight, which will not affect balance. This applies to all cars. Service recommendations for in-accessibility. Oil pump connection on bottom half of engine, oil leaks at flange could not be cured without dismantling lower half. Studs replacing bolts to be incorporated in future production. ?
