With the tensioner plug....I just tapped the allen wrench with a hammer to get it in as far as possible and then I put about all of my weight on it and it popped loose. So good luck there. As for your response to my last post...you're basically saying there is nothing wrong? I'm not sure exactly what you mean by checking the marks on the thrust washer against the towers and then the crank. The only marks I know of are the ones on top of the towers and then the degrees on the crank. Thanks for your help!
