Please Help! Leaving For AirForce Soon!

[vboy720]

Yes I trully am leaving for Lackland Airforce Base soon for Bootcamp. But before I go, I must sell my car. So I am sincerly asking help for those who know a little bit about engines, or installing the timing chain. I have a 1990 Sr20Det Redtop.

<b>The Understanding:</b> In order to install the timing chain the engine must be set at TDC, or Top Dead Center, Which also means the 1st piston is at the very top of its stroke. There are Three marking which should help me line up the Timing Chain Correctly. The marking on the left cam gear should be pointing left/up (11 o'clock ish), and the right cam gear should be pointing right/up (1 o'clock ish). The third mark found on the crank pulley/gear should be pointing down. If done right, the different colored links on the timing chain should line up parallel on top of the markings.

<b>My Question:</b> When I crank the engine to the second mark on the very left on the pulley/gear. That should set it at TDC or the 1st piston at the top. But when I go to turn the left cam gear, and then the right cam gear to the correct position, doesn't that also move the piston, thus moving everything from TDC?

Sorry if my question seems very stupid, but I dont know what exactly is moving the pistons. Whether its only the cam gears, the crank pulley, or both. Hopefully I'll Learn more in the Air Force. Any help or understanding would be greatly appreciated. I hope to serve in the military for everyone, so you may enjoy your freedom .

P.S. Any people who served Prior in the AF/Military, are welcomed to tell me about your experience.
