6.4L Knocking??

[antonp76]

I have an 08 F450 Dually with the Edge Juice with Attitude, MBRP exhaust, and Air Raid intake. I was towing (in tow mode) on Saturday and heard an extremely loud knocking followed by a EGR code. Next thing I know I back off the gas and my turbo pressure stays up 25 psi....the truck is propelling itself at this point. After a few seconds of this i proceed off the road and ease into the gas...I hear "boom" and the truck idle's but will not move. About a dozen codes followed including; Cylinder #2 failure,Crank/Camshaft failure,Fuel system press too high;Manifold overboost,etc.....

Any thoughts....I am worried to say the least.

The dealer obviously not really concerned with my problem as we rolled it off the tow truck. I became increasingly worried and annoyed when I saw 3 yeah thats right three! 08 250 with entire front end motor break downs and a 350 with the transmission out of it!!!!

Any info could help me with dealing with Ford on this as I am sure their first response will be "well there's an aftermarket computer on the truck....."

All I can say is Edge.

Care to elaborate?? Have you heard of problems with the edge chip or just against performance chips altogether>?

I had this going on with my 6.0. It sounded like knocking but would stop after warming up. Turned out to be my EGR cooler. if your throwing a code, look into that for sure

Thanks....I wouldnt be worried other than it sounded just like it put a cylinder out.

I had one in the dealer that leaked the coolant out of the rad, melted the EGR coolers and filled #8 cylinder FULL of water. Guess what water doesn't compress. Blew #8 piston in a lot of pieces and the piston pin got into the cylinder wall. 3 days later new motor in the box(well shrink rap to be exact). Hotline said NORMALLY they see failure in the #2 and #4 but #8 must have been pumping when it went out. As for the warranty, I don't know what they will say, radiator issue leading to engine failure, you might be alright, otherwise cash job.

All I can say is get ready to bend over...... U SERIOUSLY had it towed directly to the dealer before removing all your "TOYS" ouch.

Man this really sucks.

At least we get to see what Ford will do.

I hope it's covered.

I don't see how it would be covered. There is a sticker in plain sight under the hood, any modification will void powertrain/vehicle warranty. Ford has these engines at there limits of blowing head gaskets or other engine damage and then you add around 150-200 MORE horsepower with a chip and want Ford to pay for your engine failure.

I guess your dealer is one of the hard *** nazi dealers.
