i just bought a B4000 the other day and now i have a tick sound coming from the motor at an idle. sometimes its louder sometimes it is softer and i can only hear it when it is either in park or at a dead stop and the RPM's drop below 1000. it doesn't effect the way the trucks runs, it is just annoying
. could it possibly be that i need to do a valve adjust or do you have any other ideas?
thanks for your time
