can someone please answer this simple question that I somehow cannot seem to get a solid answer on........once and for all... which is TDC on a JDM H22a manual flywheel.....don't say it's the white mark because I have two marks that are white....and one that is red....the pic is what I see on my flywheel

also is it possible to have TDC on the exhaust stroke when everything lines up...including rotor pointing at #1

I can't believe I am having this much trouble with this damn timing

If I remember correctly when I set my timing, I just made sure that piston #1 was at TDC (all the way up), then made sure I was on the compression stroke (both exhaust and intake valves for #1 closed), and then lined up the 15 degree mark on the flywheel.

the 15 degree mark is for setting ignition timing

+2
the cross is the TDC mark, and is the mark used for lining up the timing belt.

your fly should actually look something like this:

l +-

l -
l15-

Ah, I remember now, thanks Steve!

It's been since 2006 that I did my belt and conversion.


And so that means that the + mark is the red mark?

15 should be 15 degrees before top dead center...

So logically the next mark on the flywheel (when rotating counter-clockwise) after the "15" would be TDC.

So basically the same thing everyone just told you lol. I'm always laaaate

yeah the CROSS is the TDC i just double checked mine, i've must of looked at mine wrong before because i thought it was the line by the 15 but it was not, i turned the crank a couple of times counter clockwise with a screw driver stuck in the #1 cyl. plug hole to double check my TDC and when i saw it get to TDC i checked the mark on the fkywheel and it WAS at the CROSS.

how do you know if the exhaust and ignition valves are closed?

The camshaft timing gears are marked to determine Top Dead Center for cylinder #1. The factory service manual tells you what they marks mean.

or

Take off the valve cover and see that the cam lobes are not pushing on the rockers. If there is any lash at all between the lobe and rocker then the valves will be closed.
