• Checking AAZ timing - maybe off a tooth by homerj1 on 06 May, 2008 13:53
• Hello,
  
  My new 95 Golf, doesn't run, attempts to starts, then backfires thru intake.
  Therefore, before going any further I wanted to check to see if the timing belt has jumped a tooth and perhaps  something is advanced too far. (I bought it this way)
  
  Would this be the procedure:
  
  1. Bring engine\crank to TDC via flywheel\clutch housing mark.
  2. Check to see cylinder 1 cam lobes are both pointing up. (as if you were changing the tmg belt)
  
  Here's where I'm not sure what to do?
  
  How do I check if the IP is timed correctly to the cam and crank?
  
  I suspect I would need to check the static timing of the ip, using a dial indicator? Is this the only way?
  
  If so, where is the best place to buy the dial indicator set up? Ebay?
  Any brand to avoid?
  
  Thanks

  Most important thing:  turn the engine over by hand a few revolutions when you're done.... that way you can find and correct issues *before* your starter  drives the valves into the pistons !

• What's that "sprocket locking tool" in your description?  Any part number or sources?

• It's the bottom tool
  
  
  
  Any parts store should carry something similar.
  
  It isn't needed for checking timing though. You only need to remove the 12mm bolt on the end of the pump to check timing. Plus the valve cover of course.
