After someone did 6 sparkplugs, on my V6 3.0L it's making a clicking/knocking sound. A 3 party said his diagnostic tester says Bank 1 and 2.

Where exactly are these located and other than putting eyes on it and checking they're fine damage wise, how else can we know if they're good?

Is this fuel and O2 sensors? Ect?
Could it just be a hose or hoses?

What do we need to do so that we're not stranded?

Thank you!

Bank 1 and bank 2 are both sides of the engine so it does tell us much. Do you have a check engine light on? If so, this can tell us which cylinders are having the issue. It sounds like something may have dropped down into the engine or one of the spark plugs is loose. Can you please shoot a quick video with your phone so I can hear the noise? That way I can tell for sure what's going on.

Here is a guide to help get the codes:

So I found the changing song. He dropped a puly on the Motor mount. The exhaust will be a next project but look like we have some but time, but now on the diagnostic reader it's pulling up as O2 sensor but those are totally good.

Last night the vehicle was starting but it almost sound like a hose was not connected or in the wrong place, the exhaust was making a little sound and it was reving itself.

I'm not sure what he did or didn't do without the vehicle won't start at all so hand me working on it more today while I'm at work.

He did forget to lubricate the spark plugs when he put them in so after lubrication when I informed him you have to lubricate them, it started up but was rubbing itself can't tell what the issue is but almost like I said a hose not connected or connected properly?

If I can hear the noise while cranking I can tell you if the engine is hurt or not? If you have an exhaust leak it will give you oxygen sensor codes. Please check out this guide for more info:

I'll try and record it for sure. Right now we're trying to find a jumper as the battery died.

It sounds like the engine still has compression, which is good, but now this post has turned into a different problem. Can you please upload this video into a new post that the engine will not start after the battery was jumped backwards?

Vehicle won't start after vacuum hoses where re-checked. Before hand, the engine would turn on but try and die, but continued to stay on if you have it some gas when it was about to die. I'll post a video with the sound it now does.
