so now on top of my hot start issue and injector issue i now have what seems to be a bad water pump. my truck will peg out on coolant temp but if i get the rpms up it will cool back down. and if i get my rpms up high enought my wastegeate will dump off all of my boost if i let off the throttle too fast. i am starting to think that some gheto rigged this truck together to sell if and get rid off thier headache. what do i do

 

There is no wastegate on a 6.0. If you let off the throttle sharply after building a good amount of boost then there is no place for all of that compressed air to go, so it just gets sent back out the intake. That's 100% normal. It's called turbo fart usually on the forums.

A bad waterpump hardly sounds like a ghetto rigged truck, but whatever. The water pumps on these have a plastic impeller. They did this intentionally. Even though it is prone to cracking, if it does come apart it wont chew apart your front cover, so it's the lesser of two evils.

Are you monitoring your engine and coolant temps? It could be a clogged oil cooler too, or it could just be low on coolant. What's your coolant level look like. When the temp gets up high on the factory "gauge" does the fan kick on?

 

With the "turbo fart" it's Like if I put my foot into it with revs out fast causing it to build boost preatty fast. Ever since i put my stack in i havnt seen it build that fast but then I let off it sounds like something youd expect out for a rice burner off fast n furious. With the coolant levels they don't rise very fast as I'm driving and all off a sudden it will peg out from cold in about 45 seconds. With the fan it will be on at start up and stay on for a couple miles then kick on as the gauge starts reflecting the temp. The turbo, from the way you make it sound, is normal system ops. But them temp I know for sure, there's something goofy happening.

I was watching a blurb on YouTube, I don't remember the guys name but he had a clip on there about replacing the o rings in the high pres. Oil rails for the injectors. He showed some nylon retainers on there. Where can I get those? He was sayin most times those go bad causing the no hot start problem. Also it seems like the hpop is a little tired as well but from what you said in the post in the 6.4 section I would be better off just building this motor

 

Yeah the turbo fart is just when you hammer on it and it builds boost up and you let off the throttle sharply. If you let off slowly it wont do that. It's not going to hurt anything, it's designed to do this.

Sounds like you may have a coolant sensor messing up? Look to see if oil has leaked on it or something. Or see if it's leaking itself. The best thing would be to monitor your oil and coolant temp with a gauge setup of some sort. The gauge on the dash is more of an idiot light than a real gauge.

The fan will always be spinning, but it works on a lock up clutch. So even though it's spinning, it's not really doing anything, as it's needed the clutch will grab and start moving some air, that fan will get LOUD. You can hear it clear as day in the cab as you're driving. Are you getting that at all? It will sound like a loaded down semi.

So you still have a hot start issue? Man, you really need some scanning software, or a buddy with some sort of a scanner. On an 06, the common points are the STC (snap to connect fitting) ~$35, the dummy plugs and stand pipes ~$102, in that order. I highly doubt the injector just started leaking, you'd most likely have a rough running truck and be throwing injector contribution codes on that bank. Did you already do the STC and dummy plugs/stand pipes?

Best tool you can have with a modern diesel truck...

 

Yes, that's what I use. I got mine from KT performance on here too.

 

I does have that loud fan sounds to it but only on start up for a couple miles and then when it starts to get hot it does it as well.

The truck does run rough. The really noticeable points is at idle and between 1250 and 1750 rpms. Another thing that stands out to me is when I take off from a stop light. It lacks power while it waits for the turbo to spool up to the point where it's actually pushing some real boost. I keep getting a p0272 for the #4. I was getting a lot of p0278 until I put new o rings on the whole left bank. I've been waiting to do the right bank as well but haven't gotten to it yet.

I need to check that stc fitting to see if it did pop off. I've also been told a mother real common problem is the oil rails. Those o rings go bad causing the same exact problem.
I just need a 3 day weekend and the seals to break into it. It looks like a pretty extensive task

 

I would start with the STC fitting, and the standpipes/dummy plugs personally. It's not really common for the rails themselves to leak, but not impossible. Shop air would be the best way to test it if you're digging it. At that point, I would still replace the parts I mentioned as they are known to fail at some point and Ford did upgrade the parts with a new design.

Man, I would really like to see the ECT and EOT readings. The fan shouldn't be coming on when you start it up, that doesn't make sense. I wonder if the sensor is bad and telling the clutch to lock up when it doesn't need it, or if the fan clutch is failing in some way?

As for the turbo lag... 6.0's are laggy beeches anyways. Tuning helps tremendously. They're worse when they're cold too, cold oil doesn't help with bearings spinning up quickly. Have you tried any Rev-X or one of the variants? Hot shots or Evergreen AR9100?

 

how long does it take to get to the fitting. ive heard some people say that you dont have to pull the turbo to get to it but i have a hard time bleiving that.

i dont have any of the programs to read that but i might have a buddy that does. ill get with him and have him get the readings of the temps. the fan does run at some random times. i did notice that on my way home this morning that as soon as it hit normal coolant temp it didnt raise any higher and the fan was on but it was raining.

i havnt but i have been thinking about getting some. would this help my injector codes that im getting?

 

Yeah the oil additives are more of a "cover up" not really a permanent fix, but they're definitely worth adding, if nothing it will at least tell you if you do have injector issues because it will clear them right up (as long as they're just sticky on the oil side). You should definitely try some.

I'd probably pull the turbo regardless, not really that much more work.

Definitely get your buddy over and offer him some beer and get some readings for us, it will help tremendously.
