6.4 carnage pics

webb06 · Apr 26, 2016

Had a truck come in the shop a few weeks ago, customer said he heard a pop noise at a stoplight and then started idling rough. He first took it to ford dealer because they told him they would fix anything that happened to it, turns out they wanted nothing to do with it now. Figured it had a cracked piston considering the massive amount of blowby. It also had a banging/clanging noise. I pulled the cab and head off and found this....anyone seen this before? This is what it looked like after removing the head. The piston is missing, assuming it's in the oil pan, and cylinder wall is BEAT, so bad that all the coolant inside the block got drained out with the oil. In the pics you can see a few spots where there are holes in the cylinder walls.

Lol! I've seen it but not on a 6.4.

There should be something on the end of that arm to keep it from digging into the round chamber.

By any chance are any valves missing from the head? That is EXACTLY what mine looked like when it dropped a valve.

Now it's a 5.6L. I had a 4.6L gas engine that dropped a valve and did the exact same thing.

I have a 6.0 here like that, cylinder isn't as bad but the piston is gone. The customer had done a egr, and hpop then drove it about 70 miles when it locked up. I looked in the cylinder with a bore scope and couldn't find the piston...lol so pulled it down. On his a piece of the piston wedged between the rod and crank locking it up, 2 valves were gone but the stems were still in the head. I feel like my customer dropped something down the intake while he had it off causing the valve to break. It only has 140k on it.

Wow! Did he actually drive it like this to the dealer and around to your shop?

superpsd · Apr 27, 2016

From the marks on the cylinder wall it looks like he did. Beats calling a tow truck lol.

78f100 · Apr 27, 2016

Here is the 6.0 I have at the shop.

bluedge8 · Apr 27, 2016

Might as well keep driving it, not like it's going to get any worse lol.

Hauled it to ford, when dropped off they said they were gunna go drive it. Not sure how far or if they even did. I started it at our shop and drove it inside. Having no idea it was like this, but the damage was already done. No way in saving that.

webb06 · Apr 27, 2016

I'm anxious to get the engine out and find out what the piston looks like.

Saw one like that out of an ambulance a while back that did the exact same thing. The entire truck was being sold dirt cheap, I was going to sleeve that cylinder and slap it together but wound up passing on the deal.

Sounds like a $15k repair bill to me.

I wonder what caused the piston failure? What a way for a motor to fail.
