[QUOTE="Geezer, post: 400568, member: 436"] I have been thinking about this. Pulling off that valve cover is a pain in the neck. I don't think the chain will move from the cam sprockets because they are on top and gravity is on your side. If you stuff a rag or something between the bottom of the crankshaft gear and the case it should hold the chain on that lower sprocket while you replace the tensioner. Another option would be to hook a spring on the chain itself to keep tension on the back side of the chain loop while the tensioner is out. If you're going to pull the valve covers to check the valves then I agree with Haulin' Ashe's advice to replace the chain along with the tensioner. I will do that next time I have my valve cover off.
