hi everyone, looking for info on my 2012 cruze 1.8l engine. It is a wreck that I had to tear into the motor to replace bent valves. I had the machine shop install all new valves from gm and now going by the cams the valves on tdc do not seem to be all closed, is this normal or are they supposed to be closed TDC? Also when the cam locks are in place is the crank supposed to be TDC position? In the Mitchell on demand it says something about rotating the gear 60 degrees against normal rotation crank gear that is, what is that for? Any help for this I only want to do this once and not bend the valves again. Thanks
