I have a 2004 F450 with the 6.0 Powerstroke. I have had 3 injectors replaced under warranty and now have another 2 bad according to the dealer 20 days after the 5 years was up. I only have 64,000 miles. Ford has declined to offer any coverage for the problem, but that is another topic. The dealer told me that injector 4 and 5 are bad. I have diligently looked all around here and on google and I can't find anything that tells me which injector is which. Can someone tell me, or point me to a diagram? I'm sure there is one here somewhere, but I have yet to find it after several hours of browsing.

I picked the truck back up from the dealer today and I decided I would try and see how hard it was to get to the injectors since I don't have the $1400 they wanted to replace them. I sort of arbitrarily picked the passenger side since it looked like I would have to disconnect and drain the coolant resevor on the drivers side, and that seemed like a mess I didn't feel like cleaning up. Man, those back two bolts up against the climate control blower (or whatever that is) are a serious pain to get out. I did manage to get the valve cover off and I noticed that one of the injectors had the dark top instead of the white top the others have. I suppose that was one of the 3 that was replaced under warranty last year. I didn't bother disconnecting the oil rail since I had no idea which one of the injectors was bad, I also didn't have the required #40 torx bit. I mostly just wanted to see if I would be able to do the replacement once I found out which ones were defective. Now I know I can get to the ones on the passenger side, I just need to know which one #4 and #5 are. I assume I'm going to have one on each side so I'll have twice the work. Thanks for any help. BTW is there a service manual you can buy?

 

Number 4 is second from the front passengers side, 5 is second from the back drivers side. Drivers side front to back 1-3-5-7 This will be very helpful https://www.ford-trucks.com/forums/5...ml#post4355612

Wait, when I look at the diagram in the 2nd reply it looks like it goes 1-3-5-7 from front to back on the passenger side not the drivers side as the first reply mentioned.

 

Pass side, all odd numbers, 1,3,5,7. Driver side, all even numbers, 2,4,6,8

 

Sorry I was just double checking that.My bad its been one of those days. Thanks, valoney I haven't seen you post in a while.

 

vloney is a lifesaver on multiple forums!!!!!

 

Hi,

Sorry that I cannot add to the repair discussion...however I did want to mention that we recommend our treatment before replacement...or as maintenance to help avoid future failures.

Unfortunately, the problem with the injectors is common with the 6.0. There is an issue called "stiction" where due to oil shearing the injectors become oxidized and fail.

Our company designed Hot Shot's Secret for International to correct this issue. Our oil additive was shown to fix the problem 86% of the time and improve it for the remaining 14%.

You can see it on our website at Lubrication Specialties | Diesel Motor Oil | Primrose Engine Oil | Fuel Additives | Oil Additives | Engine Restore|

Our customers report better performance, no turbo lag, faster starts and better MPG... etc after just one treatment!

And it is much cheaper than changing just ONE injector (and a whole lot less headache)

PLUS we offer a money back guarantee..so there is never a risk to use it.

Used as maintenance, Hot Shot's Secret will help to insure many years of faithful service from your 6.0.

In addition you may also consider switching to a synthetic oil, such as our Blue Diamond product and maybe add a bypass filter. This will help to avoid stiction as well as maintaining top performance of your engine's oil.

We have a customer who is now well past 500K with the original injectors using our system and goes 50K+ between oil changes (I can email the oil analysis)

Feel free to email or call any time with any questions. Good luck getting the issue resolved.

Dan
