Has anyone else had problems with the rocker arm shafts coming loose on their SOHC SL1 Saturns? I have a '95 Satrun and the exhaust rocker arm bolts have loosened off themselves twice in about three years. The first time I got lucky and only had to tighten the bolts, but last night the rocker arm shaft broke. Does anyone know if there is a fix for this?
