timing chain
I have a 2008 honda fit 70k miles, mark on timing chain is one link off. Is there a trick to re-position timing chain one tooth on the crank sprocket without removing the oil pan? On my car there is a raised boss which prevents the chain from being taken of the crank sprocket. As it is the key wont go in the hole on the crank sprocket. any tips are appreciated. I dont know if the chain jumped one tooth, or it was previously installed incorrectly. thanks in advance.

You should be able to do it by taking the upper sprocket loose, sliding it to the side lower it to give you slack at the bottom to get by 1 tooth, but you will need to take the timing cover off to get the tensioner loose.. (Without taking the tensioner loose I cant see it happening.. ) Matter of fact if you get the tensioner loose you can easily move the chain... Been a few months since I did mine, there are pics in a thread I did on a head gasket change..

You were right! I was able to shift the chain over one tooth by loosening the tensioner. I tested the compression before the change, and was at 150 psi. After the one tooth shift the compression was 180 psi. I set the crank pulley mark pointing to the oil pump mark and cam pointing marks as shown in the chiltons book, while watching a plastic soda straw stuck in #1 cyl rise to get it at TDC., and everything lined up, but when I checked compression it was at 180 psi. Now I'm wondering if it should go slightly past the cam mark to obtain the 200 psi?. Since the first test I also lapped the valves, and am wondering if the valves have yet to fully seat. Any thoughts?
