Hello everyone, i have a 2003 Jaguar XK8 4.2 liter and i am changing the timing chain. i noticed when putting it back together the left side of the VVT i am able to retard the intake side. i am unable to retard the right side intake, i did nothing different from the left side. i dont have the crankshaft chain connected and i am leaving the exhaust side a little loose and the intake about 20 foot pounds of torque to hold the bolt until i retard the vvt. My question is, do i need to retard the right side or is it just the left side that gets the retard? Thank you to everyone in advance for all your help.
