Where are the IVA housings on a C15?

There are 3 actual IVA/jake housings in the head (2 cylinders share a housing) and on each housing are 2 oil solenoids (these are the normal wear items which along with wiring issues cause fault codes). The IVA housings DO NOT open the intake valves letting exhaust back into the intake.

How do you adjust exhaust valve on C-15 ACERT?

Loosen the locknuts on the three jakes that match the exhaust valves. Insert the allen wrench, and back all six pistons off 1/2 of a turn. This will ensure that they are not touching the 3 intake & 3 exhaust valves you are about to adjust.

What are the valve actuators on a C-15 ACERT?

Adjust the intakes to .015, the exhaust to .030 then adjust the 3 intake valve actuators to .020, and the 3 jakes to .027. The real trick is, when you adjust the actuators & jakes, is to snug it down against the feeler gauge & wait a minute for the oil trapped inside the piston to “seep” out.

Place the appropriate feeler gauge between rocker arm and the valve bridge. Then, turn the adjustment screw in a clockwise direction. Slide the feeler gauge between the rocker arm and the valve bridge. Continue turning the adjustment screw until a slight drag is felt on the feeler gauge. Remove the feeler gauge.
