    Top dead center?
    I am trying to install a new timing belt in my 1992 honda accord and my instructions are telling me to set number one piston at tdc. How do I know which piston is number one and how do I know when it is top dead center? Any suggestions on installing a timing belt or where do I start?

    Honestly, it's a job best left to the professional. If you decide to proceed, this advice may help a lot:

    It's best to place a mark (e.g. Whiteout or white paint) on each pulley and corresponding point on the side of the old timing belt, before removing. Then, remove old belt, transfer marks exactly to new belt, and reinstall with confidence.

    Are you replacing a worn belt or is it because it was broken?

    I can auctally see in the timing cover and its not even touching a pulley so I think its broken or slipped one or the other

    It's likely an interference engine, where the valves and pistons are now damaged.

    So I should run a compression test?

    To prevent further damage, remove the timing cover or valve cover and check things out carefully. If the belt broke, the compression gauge wouldn't work.

    Removing the valve cover may allow you the opportunity to see if the timing belt is still on the camshaft pulley.
