Need to change timing cover gasket on 1999 chevy lumina, need to see how to do it

SOURCE: 1999 chevy malibu

That engine does not have a timing belt, it has a timing chain and therefore much easier to work with as it can only go on a certain way, the primary focus being getting the dots on the timing chain sprockets lined up properly.

I believe, with the engine at Top Dead Center on cylinder #1, the dots will be facing each other. That is to say, the do on the cam sprocket will be facing the dot on the crank sprocket.
