30 Degrees Off.......(Dell?)

You may remember my post from a couple of weeks ago, if not there's a link below.

Anyways, the mechanic came over to rotate my cam 30 degrees. Had to pull the hood, front end, dist., pump and everything else from the front of the motor. Only one mark on the cam gear, and it's pressed on so it must not be original.

The mechanic had installed the cam gear wrong on the cam, 45 degrees off.

We set the camshaft (less gear) to the crank at the correct TDC for the compression stroke. One problem. When we put the cam gear back on, it's one tooth off.

Is this possible? Should we just set the marks correctly and button her up?

P.S. The oil journal plug was in, so that answered that!

If'n I understand what you are describing, you currently have the camshaft and crankshaft in sync according to physical measurements at TDC. And when you put the camshaft gear on, the 2 witness marks are off by 1 tooth. I don't know why they are off by 1 tooth, but I think I'd make both witness marks match up.

Then I'd move things around and carefully watch the valves move with respect to the piston TDC..... .Dell
