after being a gm man for yrs i broke down and bought a 2006 f350 :icon_ford: strait cab long bed 4x4 work truck package. i bought it with 100k miles on it. the previous owner put 8 new injectors in it, new turbo, and a new high pressure oil pump. i am very familar with the 6.0 but i am not sure if this truck still has the egr cooler on it. how can i tell? the other thing is what should i do first priority wise? i have a buddy with a 6.0 and this is what he told me todo please tell me if this is correct or not. 1= highest priority
1.egr delete
2. coolant flush then switch to cat silicant free extended life coolant
3. custom sct tuning
4. 4 inch exhaust
5. coolant filter
6. head studs
ok thanks. i didnt check the eot/ect before i bought this is there anyway to tell just by driving it the health of the oil cooler ? or do i need to just read it with a scan tool ?
Check your ECT/EOT delta, FICMv, Fuel psi for initial health and direction that you may have to go with issues being fixed.
Then if you need to dig into the motor to fix any issue you find, replace any of the OEM parts that could cause issues down the road like STC fitting, dummy plugs, stand pipes, fuel psi spring.
The first pic below you see a "yellow X", that is what a aftermarket EGR delete looks like. But there are DIY welded EGR coolers also. The second pic is what the ARP head stud look like when compared to the OEM head bolts, I'm holding the OEM bolt.
thanks for the pictures. is there a way to replace the head bolts one at a time or would i better off just going all in with new gaskets? id like to avoid that due to expense
Even though the delta's are good I would still get the monitor. I'm on the hunt for a new Excursion PSD and had I not already had an Insight CS I would've made a bad decision and bought an otherwise great Excursion - albeit with a FICM running @ 44.5-45V. Would hate to see all 8 of those new injectors fail!!
Thanks for all the help guys. I have checked the ect/eot they appear to be good the truck has an "updated egr cooler" but I have ordered a river city diesel egr delete to take care of that. Now for the one problem with this truck the #8 glow plug is bad. Do you all think I should replace just that one or go ahead and replace them all ?
I forgot to mention the truck does haze a little when it first starts but it cleans up with in a couple seconds. I'm guessing this is glow plug related? The truck has brand new injectors, hpop and turbo
Could be the plug or you could have an FICM issue creeping up on you. You can replace just the one plug but I would suggest having a new buss bar/wiring harness ready. The old ones usually break when removing.
Just outta curiosity why do you think it's the ficm? (No disrespect intended). If it turns out to be the ficm how much is a replacement or where could I find one
FICM supplies the voltage to the injectors. If the FICM gets weak, it can cause a hard start, no start, rough idle on startup and smoking to name a few. You coukd spend as little as a $150 to $800 depending on if you have one repaired or buy one.
It starts fairly easy for the most part and runs smooth on cold starts.it just smokes for a few seconds and then cleans up.
