Almost as much work to I spect as to change. Timing belt was done 60,000 miles ago. Sounds like I'm making margaritas under the timing cover. What could that be?

Bayliner

Well I got a look at the belt, looks great! Maybe less than a grinding sound and more of a chattering sound. Am I trippin?

Normal, all these cars and anything with a 1mz have a "ticking" sound, even if you do a valve adjustment it will still be there. Do a quick google and you'll find tons of people asking the same thing with their 1mz motors...

It's not anything I hear from inside the vehicle. But with the hood open OR if standing on the passenger side of car it just doesn't sound like a "luxury" car should sound like.

I know what you mean, but its typical.... not sure what to tell you. It's a toyota thing.

Mine is dead quiet. But when I do a timing belt job I replace everything it touches. Water pump, tensioner pulley, idler pulley, and I always replace cam seals. I bet you have an idler pulley going bad. The idler pulley takes all of the vibration and force in the system. Most shops only replace the obvious parts E.G. water pump and belt. These parts all wear out at some point, but if not replaced Murphy's law states that they will fail in the middle of the expected life of the timing belt.

Could you maybe record the sound and post it here?

Bayliner

Ill post the sound tomorrow.

Bayliner

Sorry no sound bites. Took to my mechanic, he thinks it's valves. Due the the high miles and the fact it runs very well he recommends running it as is. FYI, I rolled past 250,000 miles today. Of this mobile app wasn't so riddled with errors I would post the pic.

When did the noise start? 60 K miles ago right after timing belt job?

Bayliner

I guess I noticed it in the last 5,000 miles or so.

Is your mechanic suggesting that adjusting the valves will fix the issue?

Bayliner

He says he would not guaranty it. So....wtf? Valves? Not valves?
