Yes, they're both normal and OEM. Check the cracking sealer around the HVAC box, they're often the culprit in mystery water leaks inside the car.
I had a battle with the distributor hold down bolt.
Is this coating on the firewall original or was it applied later on? There is cracking of the sealer at the left side of the HVAC box. What about that ground braid from the middle of the cowl, running behind the trans dip stick and going into the HVAC box seam - normal?
That ground braid attaches to the heater core in the HVAC assembly.
And glad to see there's SOME dirt buildup found on your car(firewall)! 😉😉😉 J.K.
I'm blown away at how clean that car is!
