I'm currently performing a Rocker Arm Piston Manual Engagement Test to see if the pistons in the rocker arm assembly are engaging, locking all three rocker arms in the assembly together.

When I performed the test, I applied 60-psi through the oil port, on the front/facing side of the head, while blocking off the relief hole. I tested each assembly by setting its cylinder to TDC and pressing down the mid-rocker arm assembly. It seemed that the pistons were not engaging.

So my question is, is the air I'm applying into oil port supposed to exit the oil control orifice on top the head (underneath the No.3 cam holder/cap)?

The air being applied sounds like it is discharging from the oil control orifice at an unknown rate; therefore, I'm not sure if enough pressure is getting the pistons to engage?

 

I'm at a loss here. I'm following Helms on this procedure. Am I missing a step here? Its hard to imagine that all the rocker arm assemblies are bad.

Need some help, PLEASE!!!
