I start it engine knocking noise?

Yep, it can be fixed but i need to hear the noise to see if it is piston/rod or valve train related. Can you please shoot a quick video with your phone of the engine from under the hood so I can hear the noise? that way I can tell for sure what's going on. You can upload it here with your response. This guide may help as well.

Let us know how it goes

The knocking noise video is first & im not sure what this is in the pic , hopefully u can help me identify it. Thanks So Much

The engine noise does not sounds good, also it looks like you found the vacuum leak. It does sounds like the timing chain system needs to be replaced, but can I ask if this is the original engine (275k miles)? If so it needs to be rebuild, if you go over this video series it will show you how step by step.

Thanks for the video and images. Let me know.

Yes it is the original engine

I cant tell if the noise is the vacuum leak or the serpentine belt that needs to be replaced. As far as the engine noise I would change the oil and filter to see if that helps, the noise is a broken timing chain guide, bad timing chain if you want to fix it. This video shows how to replace the set.
