i installed my air compressor on the van today then proceeded to start it up etc, but this time the engine noise was very clear and it was coming from the front/bottom so i took a video
or maybe a timing chain sooooo loose it would hit the cover non stop?

Yeah, even more sure of it now.

It's definitely either the water pump pulley or the harmonic balancer.

I doubt it's timing chain (tensioners or otherwise) related at all. It's the balancer.

is there any way i can see that the balancer is clearly the faulty part by inspecting it or is it the elastomere inside that shatter and its simply not something you can see with your eyes?
anything i should know before buying a puller and inspecting it?
with the engine stopped i tried tugging the pulleys with my hands to see if i could find any play, but none of the pulleys had play.( did not pull/tug the damper tough il give it a try next time)

Well it all depends on how bad it is, they are sealed bearings, so I doubt you'd be able to visually inspect and determine the problem.

I'd expect with that amount of noise, you may be able to feel for play in the balancer while the motor is off. Similarly to how you'd check for a bad wheel bearing. Just grab and push, then pull, trying to find any sort of play, or movement.

It will also help you confirm the source before you pull anything off. Do the same with the water pump, and make sure it's not that before you go pulling the damper.

In regards to the damper tool, they differ slightly, just make sure you get one that also can install a damper back onto the crank. Some have the ability to only remove, and not replace.

Other than that, it's a simple enough procedure that youtube could assist in pretty easily if you get stumped.



EDIT: saw your edit, and you saw they didn't move. Maybe it just hasnt progressed that far, as once there would be noticeable movement, it wouldn't be long before mechanical failure occured.
