ISX Rocker Shafts

[Chamberpains]

Generally the rocker shafts themselves won't be worn. The rollers going to the cams will be what shows signs of scarring, pitting, scrapes and scores. Looking like this.


And the roller will show the same type of wear.


Just give all components a thorough look over while your barring the engine over for each adjustment. But really, if you're thinking other parts may be shot, why not just unbolt the rocker set and check it out? Your already adjusting the valves. All you need to do is unbolt them. Then torque them back down after inspection.
