First changed oil (10/40 though I need a heavier oil) and added oil treatment a few weeks ago because of a loud tapping or ticking noise. Car still had noise but did quiet down. Now car has a very loud knocking noise at idling and acceleration. Almost sounds like something is hitting against something

When activating the turn signal switch, the ABS/Security/Traction lights come on, and there is a strange noise coming from the dash / speedo / gauge area. Any ideas on what the issue may be. It acts fine, when only the hazard switch is activated.

I had one Mechanic say that the PVC, pipes begin to leak over time and need to be replaced, totally.
Costing between 200 and 400 dollars, Is this True?
Resivore looks gunky?
