Hi all, anyone know what torque is recommended for the rocker pedestals in a PCM352W? And what about the exhaust manifold bolts?
Thanks.

what year? and are you sure it's a pedistal and not a stud type? Normally they are a rail type system from the factory and to have one or the other type rockers means the head's have been changed.
For the exhaust use some anti seize lube on the bolts and use your calibrated arm to torque them. Get them good and tight but not super tight.

Yeah, sorry - it is the old rail type system. Two rockers held down by one stud, I think this particular engine is around '92 (the boat is an '82) Any idea?

use your calibrated arm to torque. Get them tight but don't strong arm it, start in the center working towards the ends alternated front to back, snuck them evenly then torque them evenly as descriped. If they where pedstal studs then you need to use a torque wrench, but not on the rail systems or studs with the later be adjusted while running.

Be sure you preload the rockers.
