I wanted to let the community know that I during my rebuild I noticed something that bothered me about these guides. I had a crack in the guide and I was able to pull it back and forth, only thing holding it was the rubber that was attached to it. Also a little bit of rust on them as well.

When I was doing the install on the timing chain a few months ago the chain would not go back on either, stayed with stock chain.

Don't buy this brand of part, really poor quality.
