What do you think this noise is

[adamzan]

3.3L r50, starting making this noise a little while ago. I think it might be the distributor bearings but I'm not sure. It's the metal grinding kinda noise.

Sounds like the distributor gear.

I had that same noise a little back, it was the pulley on my A/C compressor, I ended up changing the compressor and it stopped.

Sounds like my pulley as well.

Get yourself an Engineers stethoscope and use the metal probe to touch the compressor, distributor, engine parts. You should be able to locate the noise from where it is coming from this way. The other good thing about an Engineers stethoscope is that you can remove the probe which allows an opening. You can then use this to identify any leaks from hoses by listening to the increased air velocity. A must for all toolboxes.

Long screwdrivers work fine too.
