help crankshaft problem!!!!

[jamez_cab]

can any 1 tell me if im right in saying that with no.1 piston at tdc the flat spot on the crankshaft position ring should be inline with the crankshaft position sensor on a c20let

[meritlover]

id guess and say that mark is a BTDC ref marking for the ECU position.

nice welcome post by the way.
