My mom had some surgery the other day that makes her unable to operate the clutch pedal, so I decided to use the time to give her a b'day/xmas present of a t-belt job. She has no idea when it was last done, the last time I know it was done was ~80K miles at the dealer--the car now has 212K. She thinks she had it done when she was in Texas (~130-160k), but no receipt.
So, I ripped it apart, ended up being a PITA. Someone had already stripped out some of the VC bolts, and 2 of the balancer bolts. Looked like the original WP, and with the camshaft locked down the TDC mark on the flywheel wasn't even visible. Belt looked OK, but there was a little cracking when I flexed it, and it was a D.
I corrected the timing mismatch (2x close but no cigar first go round), replaced the 3 rollers, bolts, etc. All in all typical deluxe TB job.
Fired it up, and it started well (she's been complaining of hard starting--well no wonder with the valve timing so far off). There's a noise coming from the TB area now. I'm pretty sure it's new, or at least much louder.
It's kind of a whirring, but there's a clicking to it as well. It does kind of sound like the cards in bicycle spokes. I can't really isolate the location. Sometimes I'm convinced it's the tensioner (it's normal for it to be constantly adjusting as the car runs, right?), sometimes I think it's the upper roller, and sometimes I think it's the IP. The new belt does seem to be tracking closer to the block than the last one did (1/8" of clean pulley is exposed up top).
Has anyone had a bad idler or tensioner out of the box? Could I have damaged the IP somehow that it's making the sound now? Are there MP3s of bad IPs? Any suggestions? I tried a makeshift stethoscope, but didn't come any closer to figuring it out. The tensioner can't be replaced without removing the mount, right? The tensioner can be replaced without going beyond that, right? The upper roller can be replaced without removing the belt as well, right? I guess at this point I'm going to order a new tensioner and idler, replace them and go from there.
Thanks.
