Another monday!! Customer complaint was the vehicle would not register oil pressure. Also the vehicle would shift hard when first going into gear. Customer changed oil pressure switch and tested the oil pressure. So I ruled those out.

I scanned the vehicle saw the there was loss of communication with multiple modules. Also there was a code the CAN Bus.
I tested the modules , the grounds and powers and all were good. Then I isolated the wiring harness and found that it was shorted to ground.
1 one of the wires in the can bus was severed and another 2 wires rubbing on the frame.

I fixed the cables , re-insulated , re-assembled and the truck is running a1.

Finishing up this beautiful Durango !! Had a couple of issues, but now it's running like new.

Issues fixed:
Replaced the water pump because the pulley had a lot of play in it. Those water pumps are no joke they cost almost $1000 @ the dealer.
Used a 180-degree thermostat in it.
Repalce Ac Hose and coolant hoses to the FI Interchiller. Refilled ac system.
Replaced the old supercharger with a new ported supercharger from .

Modifications:
Kong Ported supercharger
Kong 108 mm throttle body
Fore innovations thriple pump set up
E-85
FI Interchiller
10% lower ATI damper
Griptec 2.60 upper pulley

This hellcat makes close to 1000hp if not more. Its a dig monster 😈

A couple of things I missed in the video are the head was warped , which was the reason antifreeze was being consumed. The piston ring is pinched because whatever cause the damage to the head and top of the piston crushed where the rings sit at. Not allowing the rings to expand fully . Which is letting oil go by and also consuming oil. The timing was completely new. It looks like an off brand. One of the phasers was missing the dot and the pin to make sure it sits properly in the cam. This was the main concern of the customer, but it was not the biggest issue, unfortunately.
