i understand how an engine works, this isn't my first time finding tdc , just my first time working on a nissan motor, i did search, and i even have a manual for the car. and everyone says something about some mark on the cam gear having to line up with a bright link on the chain, but i don't see any markings on the gear lining up with any bright links on the chain.
i just wanted to be sure i wasn't going to mess anytrhing up before i took the gear off the cam and pulled the head.
