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. -- Neil Nicholson. 1981 Air Cooled Westfalia - "Jaco" http://web.mac.com/tubaneil http://tubaneil.googlepages.com/
