Just a quick question. While I was under the hood changing my headlight bulbs, I noticed that my timing chain had a bit of rust on it and was not lubricated - at least the part that was showing. What I'm wondering is if the bit of rust I saw means the whole thing is crap and will snap at one point and ruin the engine if I don't get it maintained or replaced. I've never had a car with a timing chain before - I know that they are very durable but I never considered what would happen if it started to rust. Is there some sort of lubricant I can try to manually put on the part that is exposed? Or should I just ask the Toyota dealership mechanic to have a look at it while he changes my oil next week? Thanks for the input!
EDIT: I meant timing chain, not timing belt, heh.
