Broken plastic guides are a symptom of a stretched chain and / or worn chain tensioner.

If you use steel guides you'll still have chain rattle start up noise when your chain becomes stretched and / or your chain tensioner wears out. And when the chain rattles, the chain will be sawing rubber and metal off the rubber coated metal chain guides which will circulate with in the engine oil (not good).

So using metal guides will not delay or prevent the need to eventually replace the chain and chain tensioner. But the metal guides will prevent the chain from rubbing a hole in your timing cover if you delay replacing a rattling chain.

An inadvertent problem with metal guides is they typically come packaged in a kit with a cheap quality chain tensioner.

Solution: Buy the metal guides separately instead of in a junk made in the USA kit and buy a made-in-Japan chain kit like the OSK brand kit because it comes with a factory quality tensioner.
