    Setting timing on 1999 STS after HG repair

    Does anyone have any diagrams or photos for this? Idk which direction to point everything when I'm reinstalling the timing chains. Any help is appreciated and welcome. I've read several posts but i'm not sure that I understand what they are saying. I don't know where the markings are on the sprockets and I don't know which direction they should point. I wish it were as easy as a lexus engine, line up the marks with the mark on the belt. Please help. :-)

    use this...........

    Remember that the harmonic balancer bolt torque is what drives the oil pump - it MUST be torqued to specs.

    Good job Sub.

    Personally, I think this is the easiest OHC engine to time that I have ever seen.

    Torque the damper bolt to 37 ft. pounds, then turn it an additional 120 degrees = 1/3 of a turn = one spoke of the damper pulley.

    Here's the Northstar timing diagram. In SOME engines the RE stamping is moved in relation to the timing dot. Use the dots, not the characters.
