Not to mention that a lot of chain-drive cars often choose cheaper or substandard materials for chain guides.

You end up with a choice between sounding like it's broken and having to spend a good chunk of a weekend dismantling it.

I've driven a lot of cars beyond that point where the chain guides don't exist... The sounds of a chain sloshing around are unmistakable :). If you're lucky it will skip a few teeth one day and give you a chance to fix it.

Unlucky, it skips a bunch of teeth and bends all the exhaust valves. I managed to salvage one of those too by driving around at high rpm until the valves had...Hammered themselves mostly straight again. Wouldn't recommend, usually you'll get an iffy cylinder or two after that that mysteriously only fire above 2000 rpm
