TOY: Re: question on cam timing - 1983 22R

["M.CLINT SEARCY" <rainwolf@xxxxxxxxxxx>]

    But I think your on the wrong stroke there. If you were to put the chain
back on the rotate the motor by hand one more time you would see that the
next time TDC comes up on the crank sprocket, your cam would be in the right
position. I bet if you check your rotor with it the way it is you will see
that it is pointing at #4 and not #1. If it were pointing at #1 your cam
would be 180 degrees from where it is now.
    If it were me, I wouldn't move anything. But I'm going to assume that
you got tired of waiting for a reply and moved it like you said. So long as
your crank is at TDC, you can install the cam with the tit pointing ether up
or down, it doesn't really matter so long at you install the distributor to
correspond with that position. In other words.

If you turn the tit up than install the distributor so its firing on the #1
Cylinder.
 If you installed it pointing down then install the distributor so its
firing on #4.

BTW....what your playing with here is a common motor building problem that
is called "being 180 degrees out".

In the future, pull the distributor cap when looking for TDC. You know your
there when you see the rotor pointing at #1.

Ohhh....and one other thing. Before you go to install the timing cover, drop
the front of the pan a bit. This will make it MUCH easier to install the
cover without mashing up the front of the head gasket like I did 2 weeks
ago. I got to do it all over again the following week to fix the leak.
