Contour Enthusiasts Group Archives Forums General Troubleshooting Is there any way to clean a VCT solenoid?

....when this is stuck open it means the oil supply to
the VCT hub on the exhaust cam is on all the time.The
reason for VCT is to give EGR.With a stuck solenoid
you have the same effect as a stick open EGR valve.The
problem is almost always caused by sludged up oilways
in the VCT control valve and sol assy.A PIA & $$$$
problem to cure.Worse case you may need a new VCT
exhaust cam gear/hub assy...also $$$$$.
