Help! I can not find anywhere how to line up the mark on the auxiliary shaft. The gear has a mark but I don't see one anywhere on the timing belt cover. Does it matter what position the auxiliary shaft is in?

On my 88 there were no marks either. All i did was line the cam and crank up then that puts at tdc. aux sprocket will be at the #1 cylinder. if not then you need to check the distributor cap and find #1 then with the timing belt off you can move aux sprocket till it get very close to the #1 cylinder. and then reinstall belt carefully keeping things lined up. It worked for me.
Hope this helps. '

It doesn't matter where the aux shaft is, but it drives the distributor and it does matter where it is aligned.

As suggested, with the crankshaft at top dead center, (crank keyway straight up) and the cam on the center mark of the three, set the distributor to fire on #1 cylinder.

Rotate the engine by hand a couple revolutions in the direction of travel(clockwise standing in front of the engine looking at timing belt)and recheck marks. Do not rotate the engine in the ccw direction. Almost guaranteed to jump teeth.:)shady

OK, thanks guys. It may be a little while before I get the engine in, but I wanted to get this right the first time.

You can also just remove the distributor and then plunk it down so that the rotor is pointed towards the driver's side fender in pretty much a 90* angle then adjust the dizzy before tightening it down...

The aux on mine has a little triangle and I always line that up with the notch on the crank pulley...then adjust the dizzy afterwards...as long as the #1 piston is TDC on the compression stroke and the cam is ligned up with the middle mark (as noted above) it should be close enough to fine tune from there...

on an '89 all the auxiliary shaft does is turn the oil pump, so don't worry about it. in like '94 they started putting cam sensors on that, so it starts to matter again...

What is your question? A few periods here and there would help. Run on sentences are hard to read. Be more concise.:)shady
