Question Timing marks...

They won't line up!
I have the book and have read it 20 times.
I've read the links on the forum that say the same thing as the book.

No matter how I do it, the timing marks just wont line up.
It always looks like one is about one tooth or 1/2 tooth off.
Rather it be exhaust, intake, or crank shaft. One is always off.

ORIGINAL: cam sprockets, tensioner pulley, and idler pulley.
NEW: belt, water pump, crank sprocket

Default Re: Timing marks...

when you wrap the belt start with the exhaust cam sprocket a half tooth below the intake cam sprocket mark. Once you get the belt wrapped and the belt seats correctly the cam sprockets will line up.
The debate on the timing marks is always around the manual says it has to be half a tooth off else the timing is wrong. The reality is it has to be half a tooth off when you are wrapping the belt, once the belt seats and you rotate the crank a few times you will realize all the marks will line up perfectly.

Its not rocket science, its just the way the belt takes up the slack. There are a fixed number of teeth that must be between the two cams, and in the same way between the water pump and the crank ect. Ultimately there is only one possible solution, once the belt is on and the tensioner is allowed to adjust correctly all the marks must line up good luck hope this helps.

as a side note, if you can snap a pic of the cam marks and crank mark position I can provide additional insight,
