Timing Chain Tensioner Question?

My 2 cents 'caus that's all I have. Whenever possible don't use a tensioner type timing chain. I had two engines (both Chevy might have had somthing to do with it) loose timing chains due to tensioner. One the tensioner disintegrated and the chain was able to skip a tooth. the other broke apart and ended up dropping a piece into the chain causing it to try to roll over the broken plastic bit breaking the chain.
