dont re-install your upper timing chain guide bolts

[p_action]

hey everyone...just some interesting info. I was pulling out my upper timing chain guides today on my DOHC, and i started to thread in the bolt that was previously holding my upper timing chain guide. I got it in and stepped back, and saw that the end of the bolt was about .5mm away from the lower chain on the timing gear...So I snapped this pic to illustrate. I know people have re-installed the bolts after taking out the guide. I dont think that's a good idea because you are running into a clearance issue with the lower chain. Take a look for yourself.

sorry...its a big pic...but its to illustrate in detail...
