Car started a god awful knocking sound today, quiet at first so I just double checked everything and it was fine, no DTCs or anything.
Driving home at 60mph all of a sudden my exhaust tone flattened out and the car leaned out for 2 seconds. I pressed the clutch in and it died.
The knocking sound now is TERRIBLE, I thought the car was about to shoot a rod through the block. Heres the code it threw (as well as misfire on #3 cylinder)
P1383 - Variable Cam Timing Over-retarded (Bank 1) The comprehensive component monitor (CCM) monitors the VCT position for over-retarded camshaft timing. The test fails when the camshaft timing exceeds a maximum calibrated value or remains in an retarded position. Cam timing improperly set
Continuous oil flow to the VCT piston chamber
VCT solenoid valve stuck open
Camshaft advance mechanism binding (VCT unit)
DTC P1383 is a check of the VCT unit. Testing should not include electrical checks. Engine will idle rough, hard starting and may stall. Diagnostics and repair for the VCT unit are located in the Workshop Manual.
I'm pretty positive that knocking sound was the valves slapping the piston(s). So at the very least I'm looking at pulling off the head (again) and getting headwork. I may need pistons depending on their shape.
Assuming I need pistons I will be buying a cheap car (<$1500) and driving it everyday, while dumping money on building the car.
Oversized valves
Port the head
Forged Pistons
Forged Rods
Clevite Bearings
All ARP
etc
etc
In conclusion: Damn Fords.
