Name that Noise>> - ZR-1 Net Registry Forums

-=Jeff=- · 07-29-2009

I have a vibrating type noise in my Z, as the car gets warmer or even sit for a short bit after being driven this noise gets a bit louder.

It was there last year, but I had a bent Water pump pulley and thought that was the issue and the tensioner was the noise..

in the video, the clank type noise is my applying pressure with a bar to the tensioner. I would like to determine the issue, although I am driving the car to Bowling Green next Friday..

I have put about 300-400 miles on this year and there are no issues otherwise

here is the link:

Thoughts?

also let me know if the video does not work.. It works on my MAC and my VIsta machine.. might require Quicktime though

EDIT: I also thoght it might be the WP itself too, but it spun fine while the car was apart

Do you have heat shields ? They tend to vibrate at a constant RPM when loose and they come loose easily. Wild guess.

Heatshields on Exhaust?

just the ones on the body.. others are gone

This seems to be up front and with a high idle the noise changes the rhythm.
Starting to think Tensioner Pulley and probably worth swapping

Pulley issue.

Disconnect the belt, then start motor. No noise, replace belt as you now know it's on the pulley setup.

Lube tensioner pulley check for noise.

Lube alternator, check for noise.

Listen carefully at the power steering pump as well (Check fluid level)

Lubed the Alternator.. no change

Need to check PS level..

thinking of buying a tensioner Pulley anyway (cheap part)

Thanks

Idler pulley, but tensioner seems 'soft'

Idler Pulley fixed the howl

New tensioner fixed the vibration noise

All is good
