Timing belt

My camshaft pulley moved during belt installation. Now I'm trying to align the crankshaft pulley marks with the camshaft pulley notches.

The Crankshaft pulley has 4 notches: 3 that are close together with a red mark in between the two. Then to the right of the 3 notches about a 1/4 inch away is one notch by itself. Which notch should I line up with the belt cover V notch to get the engine to TDC before removing the crankshaft pulley for a belt replacement? Isn't the red mark BTDC? Shouldn't I align with notch on the right for TDC?

Also, what do I line up the Camshaft pulley sprocket arm labeled 'UP'? There a two notches 180 degrees apart. 90 degrees left and 90 degrees right from the UP label. Should these notches be parallel with the ground?

Thanks in advance.

I moved the crankshaft pulley to the rightmost mark which according to the diagram is TDC. After doing this, my right camshaft pulley mark IS aligned with the "Top Edge Of Head". However, the left is noticeably lower if you look at my photo. But since the diagram's "UP" sprocket arm appears to be in center line with the camshaft pulley bearing cap behind the pulley and mine is not, I figure retarding the camshaft pulley one cog clockwise will center the pulley's UP arm and bring up the left side camshaft sprocket mark. This, unfortunately, will drop the right mark below the "Top Edge Of Head".

Any thoughts or suggestions?

The picture diagram is incorrect. The Camshaft marks are one cam gear tooth below the top of the head. No big deal. Got the engine timing down pat.

My Civic has nearly 90000 mi. On it. I live in the San Joaquin Valley of California (100 degrees in Summer)

When should I change the timing belt?

When should I have the timing belt changed? I have been told by several other owners that they changed for the first time as late as 200k miles.

Thank you.

I recently went to have my tires rotated. They showed me a huge wear problem on the inside of the rear tires. They said that it is the "cam arms" and fittings and that they need to be replaced at a cost of about $1000.
I also recently got new brake pads.
Could there be a problem where they are related?
Is the cam arm being out of alignment a common problem on Hondas?
Should I get a second opinion?

I can't view any of the images for the timing belt diagrams. I have no problem viewing images from any other website on the internet. Please look into this as this is the only reason I signed up with you to begin with.
