VCT Problem
Hi guys,
I have an issue with power loss at 5.5k rpm onwards, after much troubleshooting im quite certain fault lies at the vct.
I disconnected the plug, went for a drive and no changes. Same power at low end...and same power loss at high. I removed solenoid to see if actuator is working and it is. ticks and closes when fed direct 12v.
Power fc is sending the signal. So its not the ecu.
Now when i put the solenoid back into the head. wired direct 12v into it... it ticks and can feel the actuator moving(vibrates) however no change in idle whatsoever. From what i understand there was suppose to be a noticeable change in idle when the actuator closes. nothing happens.
Would this point to the vct cam pulley mechanism being stuck/jammed?
