Change Injectors

[JHK]

I just had a diesel shop run a check on my 6.0 (it had been running bad in the mornings when it was cold) and he told me i had 4 injectors that are bad and he wanted $3300.00 dollars to put all new ones in and I am trying to figure out if I can replace just the bad ones and if I can do it myself. I can follow directions and i have a limited amount of mechanic exp. Also do I need to get new ones or can i use reman?

Did I just explain this all to you?

If it is running ok once warmed up you probably have a case of injector stiction. Before throwing thousands of dollars at it spend $70 for a couple of bottles of Rev-X and dump it in the oil.

When it fixes your problem you can send me a couple hundred for saving you the thousands.

I have been wondering if that could be the problem. I dont know a lot about it but i couldnt see why it run so good when it was warmed up

If it is running good when warmed up I would verify the voltage on the FICM stays at 48v when running and cranking. If it does then your FICM is good. It presents just like injector stiction when going bad. IFF your FICM is good I'll give you 10:1 odds that 2 bottles of Rev-X will fix you up. I would also make sure you are running a 5wXX full synthetic oil as well.

I'm not a big believer in snake oil but Rev-X works for 6.0 injector stiction and it works fast.

Because your injectors use oil to actuate them through the High Pressure Oil Pump. When the oil starts to get dirty it will begin to effect how well your injectors cycle. You can change the oil but the clogging (if you want to call it that) generally remains and after thousands of miles, they will start to stick. Rev-X will help remove some of the buildup in your injectors. The reason why it still runs well when warmed up is because the oil is warmed up and the injectors are not as susceptible to the effects of the buildup.
