2008 Mustang GT VCT
« on: March 28, 2016, 08:31:43 PM »
Here's my saga on the VCT (Variable Camshaft Timing) Control Solenoid 8L3Z-6M280-B for my 4.6L 2008 GT.  At 105K miles, at about 4 degrees F (yikes) I jumped in and headed to work.  Needless to say this car is driven!  The engine was running rough.  Got a troubleshooting code (#5 cylinder misfire).  Parked in garage and went out of town for 2 weeks.  Upon my return, it ran great.  For about 3 days.  Then on a balmy 60 degree day it happened again.  I replaced the VCTs - took about 45 minutes.  Required valve cover removal.  Attached are some pictures.

Picture 1 - the original VCT with a piece of the screen missing
Picture 2 - VCT disassembled (non-destructively) and part of the missing screen found.  This must have resulted in a sticking valve.
Picture 3 - Destructive examination.
