Timing Chain Question

I have torn down everything to get to the timing chain and found that the "little mark" on the crank gear is right, but the cam gear mark is off 180 degrees. Should I correct it or leave it?

Re: Timing Chain Question

Rotate the crank one more turn, a complete 360 degrees, then
the marks will line up.
Then remove / replace the chain and gears.

Right now you are on compression TDC.
"Dot to dot" actually is on the cam's overlap side.

Re: Timing Chain Question

I turned it 360 and the two marks line up. But now the rotor is pointing to terminal #4. Should I correct the distributor to #1?

Re: Timing Chain Question

No, then you'd have the distributor 180 out.

What you are seeing is absolutely normal.

At TDC at Compression, like you originally had it, the mark
on the cam gear is normally at the top like you saw.

When you rotate it, 360 on the crank/180 on the cam to get
the marks close so you can align them, you are actually
putting the cam on the "backside" or "overlap" side, not
the compression stroke.

What you are experiencing is absolutly normal, don't try to
correct anything, just put the new chain and gears on so
the marks line up the same way and button it up.

Before putting the cover on, rotate the crank around several
times to make sure everything is fine. Check the slop in the
chain at several positions to make sure the slop is always
the same.

Rub lots of moly assembly lube, or Slick, on the gears and
chain and button it up.

Re: Timing Chain Question

Thanks, but sorry, I won't be the next " ".
I have absolutely no desire to be like that.

This is a great information source, ideas and experiences
shared. Like everyone here, I get lots from this board,
and enjoy helping others.

Combined there's probably at least a thousand years of
experience here - amazing when you think about it.
