As the title would indicate, I've had a bit of a catastrophic event on the top-end. Heading home from our land in Franklin, cruise set at 70 for about 8 miles, this horrible knocking starts. I threw it in neutral, killed it and coasted off to the shoulder. Nothing abnormal on the gauges. No hard acceleration. No white smoke. Nothing I hadn't done the during the 500 miles I drove the day before.
Luckily my wife was following me in her Durango. Although it make for quite an interesting sight, it did get my truck back to the land. I pulled the valve cover to find both of the rocker bridges on the #1 cylinder were broken in half. I started checking the springs and found that one of the exhaust valves would pull up 3/4" or so.
Unfortunately I had to wait until I got back from work again to get the head pulled off, but I'm grateful my brotha, SixOhh, was able to trailer my truck back to the house before I had to leave. I got the head off yesterday, and all cleaned up today, and I discovered quite a bit more than I expected to.
Here goes:
Cylinder #1 - 2x broken rocker bridges, 2x broken valves, 2x VERY bent valves, at least 2 broken springs and messed up seats, but 1 I can't get out because the remaining valve stem is bent too bad. I also noticed a crack at the bottom of the guide of the valve stem that's still stuck in the head. One of the broken valves is embedded in the top of the piston. Wall is, surprisingly, alright; nothing a ball hone can't take care of. Also, it looks like the tip of the injector may have a little impact damage.
Cylinder#4 - 1 broken spring
Cylinder #6 - 1 slightly bent intake valve
That's 3 broken springs in total, and all of them are broken at the same point. The rods are all still like new,but the face of the head is beat to a pulp. I'm pretty sure (and already braced for it) the head is trashed. Amidst all of the carnage I found, the one thing that I didn't uncover was a cause.
