I'm trying to verify TDC using harmonic balancer timing marks & distributor rotor position. The distributor is a " Hall effect" magnetic trigger type, also the engine was " disturbed" turned over with the distributor removed due to incompetence. I've got the #1 piston coming up on the compression stroke, verified by plug removal.
Haynes manual says-- then align the next timing groove on the H. Balancer with the TDC " 0" timing mark cast on the timing chain cover. Viewed from the rear of the engine, the rotor should point towards the front of the engine, @12 o'clock. For cyl#1.
Chilton manual says-- " same find TDC" as above, but shows cyl#1 " TDC" rotor position pointing towards the passenger side of vechile @1 o'clock or so. I'm confused on which is the correct setup?
