Intake cam position actuator
 

Does anyone else have rigid holes under and beside both the intake and exhaust cams actuators?

Hi Trevor, :welcomewagon: to the forums!!

Holes in what?

They are holes in the head. They appear to be from the factory but i just want to make sure.

Here's a picture from the actuator solenoid valve replacement how-to thread. Is this what you're seeing, or do you have the valve cover off?

Here's a shot with the solenoids out and the valve cover off.

And here's an exploded view. #207 is the gasket that seals the area of the actuators(236 and 237) and the center of the valve cover(around the spark plugs) to the head.

What is a "rigid hole"?

A hole drilled with one of these!!

The holes he asks about may be the 4 to 6 threaded screw holes on the valve cover? I believe they fastened a plastic shield cover that went over the coil packs keeping dirt & debris out??

Yeah, could be I use the 2 front ones to thread the studs in to support my air filter box, they are also used for the coil pack on 2006 models
