Default 3.0l V6

Are these known for being 'noisy' engines? I checked out one today and it sounded almost like a diesel, a noticeable 'clacking' from the top end. I've read these are know for toasting rod bearings once the head gaskets go...which the gaskets have recently been done.

What will a bad rod bearing sound like?

I don't know if this is just some valvetrain/timing clatter or a noisy fuel injector or what. Do these engines up a timing chain or belt? (could be chain slap)

If it does have a rod knock shouldn't it quiet down if I pull the plug wire to that particular cylinder?

Yup, if theres a lower end noise pulling the plug will help dtermine which cylinder it is.

I have noticed on mine that the fuel injectors make a ton of noise. Sounds like valve clatter in the top end.
