98 Oldsmobile SilhouetteSeptember 13, 2015My crankshaft bearings spun out can i still reuse the rocker arm where the bearings go was was 8 out- Share Tweet Pinterest Keywords:Silhouette 1 thought on “98 Oldsmobile Silhouette” Freeautomechanic September 13, 2015 at 11:21 am Sorry to hear you spun a crankshaft bearing. The crankshaft caps can be reused if they check out. If they are damaged in anyway they will have to be repaired or replaced. As for rocker arms, rocker arms are used to open and close the valves in the head assembly and have nothing to do with a crankshaft bearing. Comments are closed.
