Cam moved during timing belt change. How Bad?!!?

I was changing the timing belt on a 1997 Nissan Pathfinder. Like an idiot I attempted to tighten the cam sproket, with an impact wrench (after changing the cam seals). Now the cam sproket has moved like six teeth forward. What are the options heafter? Have I bent valves? I took off the valve cover (Passenger side) and ther was crud galore in there. Any Advise is appreciated. Thanks.Cam moved during timing belt change. How Bad?!!?
Valves are pretty tough. I doubt you damaged anything.

Quit using an impact wrench to ASSEMBLE an engine.Cam moved during timing belt change. How Bad?!!?
its fine, just line the timing marks back up and it will be ok..

if its a dual cam, than there should be a notch on both cams so they line up with eatchother, if its a single than there should be a dot or notch to line up with on the block...
If you haven't ran it, just pull the timing belt and reset the cam to the proper position. And change your oil. You might even want to take it to a shop and have them run an engine flush to clean the junk out.
you should be fine. just put your timing marks on the crankshaft, cam shaft and distributor to TDC. then reinstall your timing belt, and turn your engine over by hand to feel if anything is binding. if all is good, start it up. you shouldn't have any problems. if you feel uncomfortable with it, get it towed to a shop.
