1.8 engine timing mark Options

[mcericmc]

There is only one timing mark on my 1.8 fan. It's visible through a notch on the rear side of the fan via the inspection port. Pelican parts info says the mark is TDC. Auto Atlanta says it's 7.5 degrees BTDC in the 914 tech tips 700 book. Can someone please tell me which is correct? I need to make sure the timing and valves are adjusted properly.

You are correct. That's how you time a stock ljet. (Although claiming that "only" 3500 or so rpm for djet is "ungodly" is a stretch. We regularly run our motor well past these "ungodly" RPMs. (IMG:style_emoticons/default/smile.gif) )

But, the Ninja never said that's how to time an ljet motor. He merely said that when he first ran across an ljet fan that had only one timing mark (at 7.5 degrees), it was puzzling. Makes sense when you are used to two marks. One at TDC and one at 27 degrees.

Things would be more helpful if VW had marked TDC on all it's fans (for example, bus motors, ljet don't have TDC marked).
