Hey all. Last week I started up the soob (2009 Manual Impreza) and heard a light humming coming from the timing belt cover. Turns out that the belt tensioner in the timing belt assembly had slowly backed out of the block and was digging into the cover. I quickly pulled it into the shop before it got any worse and got to work digging into the problem. The tensioner bolt appeared to be stripped so I helicoiled its hole on the block and reinstalled the tensioner with no problems. White marks on crank and both camshafts lined up properly and pin pulled on the belt tensioner. I go to manually spin the crank to check my timing and I hit some kind of blockage at either 1/4 or 1/2 revolution, no matter what camshaft combination I try. I never cranked on it too hard and all 4 spark plugs are out so I know its not compression. I'm scared I somehow bent some valves. The sound appears to be coming from the passenger side of the engine so I took off the valve cover but am unsure of how to check if any valves are bent. I did use the starter and breaker bar to get my harmonic balancer bolt off which I read somewhere on here could be bad. The timing was still on when I did this though so I feel like it shouldn't have caused the issue. Could I have somehow bent my valves or am I doing something stupid?? Appreciate the help.
