faulty nissan skyline cam gear
my nissan skyline with a vq25dd engine keeps jerking between 1800 to 2400 rpm and throws the check engine light. my mechanic says its a faulty cam gear /vtc pulley. one of the cam gears makes a click on attempted rotation which my mechanics points as the fault in this cam gear. i recently got a used cam gear from a fairly used car and this one also makes the click. so my question is, will a good cam gear make a click on attempted rotation?
