I'm pulling my hair out trying to find info on this truck. brake warning lamp and chime comes on interm while driving.managed to figure out how to get codes from "black box"drivers kick [panel. i have a code 03.problem is if continue driving rear brakes smoke-info i have so far is when pressure drops below 60psi lamp on.this is electric hydr brake system.when i drive pressure readout never goes below 80psi. hopefully someone in here has some input. THIS IS A NONE ABS SYSTEM.Not sure of type, it's a hrdroboost setup but has it's own electric pump attached to hydroboost unit w/pressre senser.

first 6.4 engine knock in shop-rem and disassembled-mains toast removed waterpump and found front cover etched out porosity galore and waterpump impeller ground down. my question why didnt enhanced fail safes disable motor. replaced rad on another 6.4 2nd time.removed waterpump for inspection and what do you know cover is showing signs of wear and porosity at 8k. have anybody else seen this?

MY FIRST 6.4 OIL LEAK AT 2100MILES WAS SAME.HAD TO PULL CAB THIS WAS BEFORE IN CAB REMOVAL PUBLISHED.YOU THINK THEY WOULD HAVE PUT A STUD IN TO ANCHOR DRAIN TUBE, BOSS IS ALREADY ON TUBE!

I USE IT RELIGIOUSLY.I SAVES MY OLD WORN OUT BACK

am in the same sinking boat as all.it's not our fault 6.0 is under engineered.am getting sick of TSB time cuts.my only hope is to make it another 8yrs then i'm outta here

I SEE MOST "REAR MAIN SEAL LEAKS" AS CKP/CMP SENSER O-RINGS AND OR BED PLATE SEALS.HAVE FOUND MANY WORRY MARKS ON CRANKCASE TO BED PLATE SURFACES. POOR QUALITY CONTROL MAYBE PERFORMANCE DEVICES.ON THE EARLY 6.0 MOSTLY ICP SENSERS AND GLOWPLUG HARNESSES
