mphil804 Posted February 9, 2006 Share Posted February 9, 2006 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. Quote Link to comment Share on other sites More sharing options...
fidgits Posted February 10, 2006 Share Posted February 10, 2006 a bit of rust doesnt mean its gonna give, but yeah, you should really have it checked, as if it goes, it'll do a lot of damage... I edited the title for you. :D Quote Link to comment Share on other sites More sharing options...

I edited the title for you. :D I have about a month left on my powertrain warranty. Do you think that I have a case to get it either repaired or replaced on warranty because my mileage has been subpar due to slackening in the chain and possibly the rust (not to mention that it has a possibility of failing)? I'm taking the car in for an oil change next week and I wonder if I could have my dealer look into that while it's there. Quote Link to comment Share on other sites More sharing options...
mphil804 Posted February 10, 2006 Author Share Posted February 10, 2006 Update: I was terribly mistaken and it wasn't my timing chain that I saw at all, but my serpentine belt. So I would like to know if a small amount of rust on that would be a big problem? Quote Link to comment Share on other sites More sharing options...
