    I replaced the head gasket on my 2001 alh tdi Jetta and when I went to start it the tensioner was not tight enough and it jumped time. Luckily it did not bend any values. I would like to know how to get it back in time so I can get it fine tuned.

    You have to "reset" the belt. AKA repeat procedure and not outcome.

    Yeh you need to line it all up as per the faq or diy index pages. It's pretty straight forward though.
    Once you've got it all lined up then you can reset the tensioner or replace if need be.

    So how do you know you don't have valve damage? If you turned over with it out of time, you probably do. TDI valves do not bend, they compress when you have a valve to piston collision so you could put it back in time and it would seem to run fine until a valve head drops off into the cylinder within the next few thousand miles.

    TDI's are interference engine and being even a tooth or 2 off will cause valve to piston damage.
