Good morning team, 1995 wrx
I recently had a tapping noise from the driver's side head, popped the rocker cover off and started to check the valve clearence. Inlet cam is all correct and all with in tollerence ( under shim style bucket )
The exhaust cam.... The bucket furthest from the pulley is tight about .06mm so say just out side of tolerance however the 3 nearest the pulley you can push down with your finger so the biggest feeler gauge fits in ! ... Surely this is wrong and almost feels as if there is no pressure ? Does anyone know how these work ... ? Would it be a case of replace buckets or do we think there could be an underlying issue causing this ?
