Subject:      Vanagon/Jetta timing issue. Use RPM sensor hole to find #1 TDC
              mark?
Content-Type: text/plain; charset=ISO-8859-1

Hey everyone.

Haven't got my Jetta ABA 2.0 engine started yet. Timing sounds wrong
even though I have timing marks "correct".

When engine turned over, it sounds like this:

 "whir whir whir" (slight pause) "whir whir whir" etc. It sounds
labored with very distinct "whirs" if that makes sense.

Starter is fine, as is battery.

I need to confirm TDC of #1 cylinder, but obviously can't see the flywheel.

Bentley shows a gear attached to crank, that RPM sensor "reads". There
is a factory gap on gear. (2 teeth missing). RPM sensor reads this gap
as TDC for #1 cylinder.

With sensor removed, and gap on gear lined up with RPM sensor hole in
block, crank pulley mark is at 9:00 and distributor points close to
#4. This somewhat confirms my suspicions. But i"m not certain.

Anyone know if I can use this gap on the gear as reference for #1 TDC?

This is an interference engine AFAIK, so I don't want to screw with
timing any more than I have! --- :^)

Thanks,

Neil.
