Last night I was trying to find the timing marks on the Harmonic Balancer, but there is nothing stamped on it. Does anybody else that has a LTR 330 know if they have the timing marks?

There's no distributor, so what are you trying to accomplish?

There are 2 CPS sensors on the front of the crankshaft that tell the ignition system where the engine is in its rotation. That's how the computer/ignition control unit of the Northstar ignition system determines when to fire the plugs. IMHO advancing the timing would be bad since the air/fuel tables are speed density. Messing with air/fuel/spark will just take the engine outside of its designed operational parameters and could lead to internal damage if you lean it out too much.

Not trying to advance timing, trying to set valves. Instructions call for setting #1 at TDC then to set the the rockers for certian valves (don't have the specifics in front of me). Then rotate the engine one turn, this will set #6 at TDC. Then set the remaining valves.

Aaah. They're hydraulic roller lifters, so you just want to get 'em to zero lash plus 1/2-turn. Pull the plugs so the engine rotates more easily and then rotate the engine until the roller lifter is on the heel of the camshaft.

Thanks for the reply! Great video. The way that the video describes the procedure, is how I did it. I was just surprised that there was not a timing mark on the harmonic balancer.

do it with the engine running, that way you don't have to worry about a lifter bleeding down
