The descrepency between perfect installation mark alignment and 11 degrees off with dial indicator test is just too great.

I expect that there is something amiss with the particular spec. you are using. You could very well be right about a California being that much different, but I don't expect that to be the case. Camshaft profile on a diesel should have little or nothing to do with emissions.

As far as the perfect alignment of the installation marks at 204,000 miles, I don't find that hard to believe at all. Even my daughter's engine that turned out to be poorly cared for with worn out cylinders had perfect installation mark alignment.

These cars have a double row timing chain that you could use to lift a battleship. I doubt that you have any stretch at all unless the PO rarely changed the oil.

The failure of the timing chain in these cars is much more often attributed to low oil pressure which renders the tensioner less than effective, or broken guides.

I hope you can find the exact information so you can use the dial indicator to put your mind at ease.

Good luck,
