Need help please

[Rivan]

Hi huys, I hope I can have someone pont me in the right direction where I need to look. I guess I`ll start by giving you what my ride is then what I know about my issue.

My truck is an `05 F-350 CC SB
I just bought it this past summer because my old truck was just too under powered for towing my 5th wheel. I needed to replace the batteries after I got the truck, and found a parasitic drain (instrument cluster (fuse #2))

My issue is that when I start the truck, its rough, and seems to run rough unless I let it warm up for a good 10-15 minutes I also notice quite a bit of smoke in my exhaust....a bit blue-ish in colour. I have no codes show up on my cts, and ficm voltage is never gone below 47.5 and batt. volts drop to about 11 when cranking but stay around 12.3 until glow plugs turn off then voltage goes up to 13.6

I don't know if all that is relavent, but there is all I really know.
Thanks in advance for any advise

Are you just watching the FICM voltage through the CTS?

I have tested it with the multi-meter also....I automatically suspected the ficm before I got my cts. I noticed no change KOEO and engine running....same readings as the insite.

You have to check it while cranking to properly check it. KOEO and running do you no good.

Had my dad helping me, and tested it KOEO, cranking and running.....no change what so ever....I'M thinking a bum-injector or something IDK

What I would do is change your oil to a 5w-40 synthetic like Shell Rotella T6 and get a couple bottles of Rev-X and add to the oil. Maybe you're getting some stiction issues.

that's the right start.

[Rivan]

ok....its about that time to change the oil anyways....and you say to put 2 bottles of rev-x in with the oil? do I need to keep adding rev-x with every oil change after on also or is it the one time until it's needed again.

Thanks for your help guys. This is my first diesel truck, and I thought I did a lot of research before I bought it. I knew about the issues that are common with the 6.0L (like the FICM and EGR) but I have really learned so much lurking around on this site since I got the truck.

I know I have to start forking out a lot of cash to bullet-proof it but I think it'll be worth it. I really fell in love with my truck since I got it, but I really do need to do something to fix my ride because my fuel economy has gone down the toilet....my CTS has my average in the 7MPG range

Don't calculate your mileage with electronics. Hand calculate it with actual miles driven divided by how many gallons used.
