Might be a good time to employ a borescope.

I have gently bent all of mine back with no known issues.

It's a 2008 6.4L with 88,000 miles, misfiring and smoking badly due to a broken y-pipe. Cylinder #1 intake rocker failed at the fulcrum. The ball shows some wear and the socket in the rocker has split on both sides. I found the rocker, ball and the clip laying on the head. The pushrod is in excellent condition. The valves are fully closes and freely open and return so that is not an issue which I expected as if this were the exhaust side things might be different. I looked at other rockers and found them to be perfect. I pulled the turbo oil feed banjo bolts looking for signs of poor maintenance but found no crust. So I am approaching this as a simple isolated part failure. Anyone else see this?

How was the marshmallow?

Yep. And the irony is that I use the Internet to look up medications that we take. Great for knowing what they are supposed to do, interactions and so forth. This is a great analogy as I hesitate before putting any medication in my body. No different than knowing what you are pouring into a vehicle.

I haven't seen any recently but it seemed that for a while it was common for the fittings to blow apart and leave a mark on the rear cover. I often thought this was causing stress on branch tubes leading to those failures. Some seemed to rest on the cover which held it together for a while and created an odd noise that was detectable at certain RPM's. I have some pictures of a few and here are a couple of pics that Steve Mutter posted:

I actually think it is a good thing. Ever try power braking a 6.4L? It does the same thing... at least the ones I tried doing it to did.

Our F&I manager is driving a 2011 King Ranch with a 6.7L. He came to me and described that the accelerator was intermittently completely dead and then the truck suddenly snapped back to life. Scared him trying to speed up getting on the highway once too! No DTC's. Ran OASIS and came up with SSM #2456. I know a lot of people who drive with two feet and I can see this coming up more and more. Once I asked him if he drove with both feet he made it a point not to... and solved his problem. I think this is a good feature but some people are going to have to learn how to drive again.

Ohhh I dunno, I think the I-6 Cummins sounds pretty damn cool. In fact, we share our shop with our Dodge store and there are many Cummins engines in the shop that sound much nicer than a 6.0L ever did.

I'll bet the rotary enthusiasts are just as bad as the diesel freaks.

Organic is just a nice way of saying that the veggies are fertilized with unprocessed shit. More or less. We fertilize our lawns with cow pee. Talk about usig ALL of the animal!

Yeah Dwayne it does look like it almost belongs there. I would like to know how much smoke it belches during normal driving though. It is a little unsightly. How the heck would you get something like that to pass inspection?

I like... Pie.

I had two of those this year and one was in my Freestyle. Whuch reminds me, I need to check it again.

So much... yet so little. There are a few good cutaways in this film... I thought of Bruce.

Me too, like the same deal in my Explorer.

In light of QCI sheets and forms... not to mention repair orders that we write up we are reminded that what we are responsible for everything we do because of the implications of our actions, or inactions. Our negligence can be easier to prove than it is to defend. If we say we inspected something or we measured something we had better have actually done so and accurately documented what we did. Unfortunately the automotive business is full of deceitful and incompetent people and has earned a negative reputation that affects all of us to some degree. We all know many good, honest technicians, writers managers and business owners whom I believe represent the majority of those in our business. Unfortunately we all start out with this hanging over our heads from the word go and it doesn't matter who you are or where you work.

We get 0.3 for them... and they DO WORK in cultivating business. I know for a fact that most vehicles I work on simply would no get an overall inspection if I was not required to perform the QCI. We do sell a lot of NEEDED work from them and I also see customers returning for, and requesting, work like brakes and suspension repairs BECAUSE if the inspections. Quality Care Inspections (QCI) [*]They work . [*]They bring customers back . [*]Customers like them . [*]They are valuable to the customers and to you/dealership . [*]Most of your competitors use them or something similar Our dealership, while not being a high volume store by comparison with the others in our zone consistently shows high penetration numbers and scores high on brakes, tires and battery sales. I sympathize with other techs who don't care to do the inspections because it doesn't always feel like it is benefiting you at the moment or is "wasting" your time. Some days I have the same feeling. But, I can assure you that making the QCI part of your every day business practices you will see increased business and higher customer satisfaction. A few extremely important points [*]All items MUST BE PERFORMED . [*]The sheets must be completely and neatly filled out . [*]Measurements MUST BE ACCURATE

When you accessed the valve covers did you remove the oil rails and inspect the injector inlet o-rings? Did you air test it with the valve covers off? You can sometimes see oil vapor coming from the leak with the air hooked up... also you can shove a stethoscope tube down along the push rods to check the branch tube... but if I am not mistake they usually break near the STC fitting... thinking here... Check all of the plugs and seals on the oil rails...

The only 6.4L injector number we show is 8C3Z-9E527-A

I knew it was too simple to be true. Thank you for chiming in. I guess then urea would actually be the most accurate term then.

That would be a great question for the original poster to ask the engineer he is in contact with. I might assume this is an Hot-Line contact. Ask them if replacing these bolts one at a time is acceptable/warrantable. Then again, Ford kicks claims or reviews them asking why we did this or replaced these bolts or that seal... I don't think the peeps in the warranty dept. consult or understand the workshop manual.

So I understand this correctly AND it really is that simple. Yes?

Technically, yes. We discussed this once or twice before. (don't have the time to search for the threads right now) Someone had one of these bolts that had broken. I believe you can get the bolts and replacing them one at a time is how you would go about it. I believe they are TTY bolts, like the flywheel bolts and should not be reused.
