Recently started hearing a clicking noise at idle and just as you start off and took it to an honest local mechanic I know. After removing the fan belt which was well worn with 170K on it, and ruling out water pump and such, he decided it was the timing chain. Long story short: 6-8 hrs labor and nearly $500 worth of parts. According to him, it might just keep clicking for long time or potentially could break anytime. Dang it, I like that car, its clean, good shape, uses very little oil, but am not inclined to spend $1000 on it either. Was thinking maybe this spring I'd get a new Accord or something so I guess i'll keep driving it till then. Might sell it outright but will give buyer the info on the chain. Some guys can do that kind of work and it might be a deal for them.
