I’m replacing my timing chain. Everything is in good shape, the tensioner was at the end of its stroke but the chain was not slapping and didn’t rub anywhere. The guide and tensioner blades are in good shape but they are hard, they absolutely don’t feel like rubber but are like hard plastic. I know that David Silver has a replacement for the left guide but not for the tensioner blade. I also saw here that some had bad experiences with the replacement guide blades failing. What is the general consensus, reuse the existing ones or go for the David Silver left guide and try to find a tensioner blade that is still soft rubber?
