I believe the when you turn it over by hand the rockers work because you do not have enough oil pressure to activate the solenoids. You have enough when you crank by starter. I don't think it should work at idle. Like it was stated before you need the proper oil. If it is too thick it will activate the deactivation solenoids to soon Matt


But why does this only affect ONE of the solenoids and not the other 3? As I mentioned it is only on the number 4 cylinder. Could that solenoid be bad and is there a way to test it? And final question, if it is the oil and assuming the solenoid is good, do I need to change the lifters on number 4 (I forgot to mention that I bent push rods on that cylinder) along with the push rods only? FYI these lifters are $200 EACH.
