Looks like part of the chain guide.

I second that it looks like part of the chain guide. If the engine is non running, take the timing cover off and take a look.

Yeah I would assume it is cause thatís the only plastic piece that looks black in the engine but if itís broken could it cause bad timing or just noises?

Depending on what part of the guide broke it could allow excess slack in the chain or even cause it to bind which could easily cause you to jump timing or even break the chain.

The chain is really tight and I still see the black piece still looks like itís intact at the top, a engine camera is coming today, so Iím going to check out the pistons and valves and see if they are damaged and if they arnt then Iím prob just going to replace the chain.

Do you know why it's not running? Is the engine currently timed correctly?

I think your best bet is (assuming it's in time) is to do a leakdown test, and carefully spin it by hand. If those tests are good, then get a new timing kit (not just the chain). OEM is your best bet for quality. If the leakdown shows issues then you'll have other considerations for repair.

Engine stopped at a stop sign and the starter would just spin, thought it was the starter so I had someone try to push start me and I would dump the clutch in first to start it, itís had a huge backfire towed it home and all the rockers were broken pins everywhere, when engine camera comes Iím going to look and update with a new post.

Sounds like it jumped time. Could have fubared your pistons as well as screw up the head. Buy or barrow a boroscope and look down in the cylinders. I wouldn't spend money on timing chain or head components until verifying cylinders are in decent shape and going from there. Might be easier to just source a junkyard long block.

This. I would think it's 98% likely you're going to need to pull the head. I can't think of a situation where you lost that many valvetrain components without damage to your valves and pistons. I'd say used longblock is most likely the economic fix.
