The VCT uses oil pressure to change cam timing. The VCT solenoid might be open (infinite resistance) or the port on it can get blocked by varnish/sludge. Unplug the connector and check the solenoid with a meter. Good clean 5W-30 is a must. If the oil has not been changed on time, there could be gunk buildup in the crankcase/oil system keeping it from moving.
