I understand that exhaust runs through the EGR. what I don't know is:
Does the EGR valve control the amount of exhaust into the air intake?
If so, does only the amount of exhaust let through the valve go through the EGR?
if so, if the EGR valve is closed then no exhaust will go through the EGR?
I'm looking at maybe trading for a 2004 F350 with a studded and deleted 6.0. It has a "thumping" sound coming through the intake like an exhaust valve is staying closed. My question is, how common is it for the rocker arm retainer or rocker itself to fail? It has 204k miles, and the owner says he was on his way home about 2 weeks ago and it just started doing it.
View 3 RepliesI have an emissions test coming up. I have 3 P codes that I'd like to eliminate before then. I don't want to "fix" the issues they are telling me about. Just make the codes go away. I know why they're there I just need to get rid of them.
What I have coming up is:
P0475 Exhaust Pressure Circuit Valve (result of EBPV delete)
P0541 Intake air heater A circuit low (result of aih delete)
P0640 Intake air heater control circuit (also result of aih delete)
What resistors I'll need and where to put them in?
2007 F550 with the 6.0. About 2 months ago I replaced the EGR cooler with a Bulletproof cooler. Truck ran well for a few weeks. Then I started getting the "turbo fart". I stopped using the truck until I had an issue with another truck. I was stuck so I sent the 07 out without cleaning the turbo. This morning a decent amount of white smoke started coming out of the exhaust. The smoke would sometimes get a bit gray. Going up hill it didn't have much power at all.
View 8 RepliesMy truck threw a CEL after the first start today. The CTS reports it twice. I noticed it about two minutes after start.
P02E1 - Diesel Intake Air Flow Control Performance
The air box gauge is green and it doesn't reset when I push it so that appears to be fine.
The one thing I can easily notice is the sound of the turbo. Typically when I stop and park, the turbo spools up, then down, then spools again and gives a sigh of relief and it's then silent. It's not doing that currently.
Now, I can hear it constantly when parked and it spools down after I turn off the engine, even two minutes later. That is not normal for my truck when I wait for the above to finish its routine. When I start the truck, the turbo immediately spools to where I can hear it which is also not normal, as if it's building 0.5 psi. I realize that's funny to say on a turbo diesel but I know the sounds of my truck. The EGT's are fine, EOT, ECT, TFT are fine and I can build boost when driving without issue. I took the drive to work easy this morning so the highest I noticed was 10 psi.
I restarted the truck after a 20 minute drive to the office and it didn't clear the CEL. The CTS squawked four times when it woke up the second time but it didn't show me which PID it was upset about.
I'm thinking this has nothing to do with the CAI and this is something downstream of there. EGR related? I haven't opened the air box yet, at work and in dress clothes so that'll need to wait. My past four or five regenerations all started between 1.94 and 1.97 soot gpl. That is also not normal and is something I have been keeping my eyes on. Currently the DPF is at 2.10 so it has made it further. Normal behavior (post emissions flash) is above 2.54 soot gpl for an AR.
I have this sensor unplugged. Is there a way to defeat this sensor so I don't pull this code?
View 3 RepliesI have a 2007 F350 with 140,000 miles. I just received my first oil analysis from Blackstone and it shows a small amount of coolant in the oil (296ppm Potassium, 30ppm Sodium). Iron at 47ppm and Lead at 12ppm are elevated as well. This is at the end of a 5000 mile oil change.
I have no oil analysis history to say if this has been occurring for any length of time, and have no runnability issues. Oil/coolant temp delta is 8-10F unless towing, and I have seen no coolant loss since replacing the degas bottle a couple of months ago.
Where to look first. It seems most oil/coolant encounters result in the oil going into the coolant, not the other way around. I haven't done an analysis, but have not seen any oil residue in the degas bottle.
BTW, no coolant shows up on the dipstick either, so it is a small leak at best.
my egr delete j pipe orings give me trouble and i replaced but broke a bolt, now i think that big donut oring is leaking, i was reading you can put a 3/4 freeze plug in to eliminate any coolant into the intake, where does the freeze plug go,front cover or intake and does coolant still pass thru the j pipe?
View 7 RepliesWhere the air intake for the cabin air conditioning system is? The past several trucks I've owned had a cabin air filter which I replaced annually. They get filthy and I can see why this dirt should not get into the evaporator coil. It will reduce air flow and here in Texas we need all the air flow we can get (106 today). It shouldn't be too hard to improvise a filter to wrap over the intake (for a cheap fix).
View 3 RepliesI just replaced the oil/egr cooler, stand pipes and dummy plugs along with all suggested upgrades, just filled with oil hooked up batteries and while filing with coolant it started gushing out from under the intake in front. I think I see an o-ring pushed out.. I hope I can lift the intake without removing the turbo!!!
View 1 RepliesI was chasing down a P2074 CEL and thought it was a stressed wiring harness connection on the MAF.
Took it to the Ford house and they chased it for 2 days, believing it was the MAF and air filter. They told me that air filter was allowing to much air in. My thoughts was, that is was what MAF is for, to regulate the fuel based on how much air was going in.
I just found out that they are stating that an AFE dry air filter contributed to a cracked intake manifold because the aftermarket air filter made the intake get too hot.
Anyways, I've been doing a lot of work on my 6.0 2004 Ford Excursion lately, and recently installed my Sinister Diesel intercooler pipes and intake elbow, and had to remove my throttle body completely to do so. I know that the 2004 models throw codes when removed, and that's what I'm here for. Mine isn't dogged down and actually runs even smoother with my new piping and intake, but I want to get rid of this code.
Is there any tune out there that can erase it? For some reason my Edge Insight CTS2 sees the code, but my SCT X4 flash tuner doesn't see the P0488 code. I know people have discussed this topic several times, but after hours of reading through posts I never found any solution to this. All I need is a way to delete the code because I don't like having my CTS2 with a trouble code for something I did on purpose!
I I have a pretty good o ring leak where the egr cooler meets with the intake. My question is can i replace the o ring without removing​ the intake. If so what is the process.

View 4 RepliesI've topped up the DEF and the warning is still showing that I'll have reduced engine power within 45kms.
Its weird, just yesterday it showed 550kms to empty so I added one full container, all day it kept showing less and less kms' til empty. Warning lights and bells etc.
This evening topped it completely and still shows. Is there a way to reset it without having to stop at the service dept.
I need to remove my EGR valve to clean the unit of carbon. While there I will be removing the intake elbow to check if I have the throttle plate installed on my engine. What the part number is for the gasket / o-ring that seals the elbow to the intake manifold??
View 7 RepliesUnder light acceleration without any load. The motor backfired through the intake. Lost all boost. Other than the backfire noise the motor seems to be fine except for lack of power due to no boost. The motor has been serviced by Ford Dealer since new. All services have been done at 5K mile intervals. The last service was done at 60K miles. All filters had been changed at that time (oil, air and fuel).
I do have experience with turbo/ supercharged motors. My experience would tell me that the problem was with a lean condition at the time of the backfire. Plenty of fuel in the tank and no low fuel pressure warning. I have seen low fuel pressure warning in the past but it happened during the winter when temps were negative 40 degrees. The truck is still under extended warranty so I really don't have concerns regarding repair costs.
I have 2 messages showing up in the message center / control panel. I have taken the truck to the dealership and we cannot recreate them while the truck is at the dealership. How it can be resolved.
2013 Ford Superduty Platinum : 33,800 miles and the truck is stock

This will happen just driving down the road or just after starting the truck and taking off.
It has happened towing my work trailer and also not having the trailer connected to the truck.
So I've been chasing a problem in my 07 6.0 for about 6 months now I had just changed the oil cooler and a week later was driving home and she quit a mile from my house I have since then changed the cmp sensor the alternator 3 injectors all the o-rings in the nipples of my oil rail both down tubes in the oil rail and the IPR valve most resently and last night I hooked it up to me auto engenuity scanner and the IPR valve is still not closing it stay at 14.84% the whole time I'm cranking. The only code I'm running is cmp sensor low a cuircut or something like that I can't remember the number.
View 14 RepliesFrom what I understand it should be dry where the valve goes. I would call it moist not wet but fairly moist. The top groove had the most wetness, the middle groove was dry and the bottom was nearly dry. Where do I go from here - the video I watched said to scrape out and vacuum - not dry enough.

My friend attended a powerstroke diesel class last week. During the class the person doing it mentioned that if you are going to do a EGR delete on a 6.0 you need to install a blow off valve. He said that the 6.0 will open the EGR valve if you over boost and since you deleted the EGR it will lift the heads. He said that the unision ring wears out which will cause the truck to over boost causing the over boost situation.
