Cam timing marks
Posted 20 April 2012 - 09:59 AM
When I do the valve timing, with the correct number of pins the timing marks were not exactly vertical and horizontal. If I lined up the timing mark, I could get the exhaust cam just right, but the intake would clearly be late.
Just to make sure, I changed my timing chain, and it greatly improved the alignment, but it is still not exact still. intake cam is still a bit late.
Are these things normally exact?
Is it a case manufacturing thing, or does this indicate some wear of the cam gears?

Yes, I am at the correct number of pins. Before changing the chain, it was about 1/2 to 3/4 a link off. Afterwards I might describe it as 1/8 of a link...

The point is, when the exhaust cam is lined up perfectly, the intake cam is a little late (one dot a little below the case and the other dot not exactly vertical. (with the correct number of pins between) replacing the chain helped a lot, but I guess I was expecting it to be spot on.
