Hey fellas,

Did some research on here already but still a little worried. Any help would be greatly appreciated. I have a 2010 F350 and about a week ago my check engine light randomly came on then after about 30-40 minutes (I think) it went off. That got me a little concerned so I started to pay more attention to what I was hearing or feeling. After I stopped I looked under the hood but didn't really notice anything different. Then I checked my codes on the tuner and again, nothing (yes a DPF delete and SCT tuner so no warranty). The past few mornings it had been around 15 - 18 degrees F here so when I started it there was white smoke out of the exhaust. But as cold as it was I wrote it off as just being a cold engine start. This morning though I noticed what I thought was a lot of smoke. Went to the back and it didn’t really smell funny but I started to research it once I got to work. Found where to look if it was coolant related. I looked for white splatter and rust deposits. All the hoses, underneath and on the driver’s side through the wheel wale all looked good. Then I found that the degas bottle was below the cold line (again it has been cold but I have checked before and thought it usually stayed right around the lower line no matter what the temp was, could be wrong). The last and worse place I checked was where the cooler for the EGR bolts to the EGR. These pictures are what I found.

So you can understand what you are looking at I highlighted the EGR temp sensor and you can also see the fuel and oil filter caps. There is a rusty color by the threads of the sensor and the nut that holds the cooler on.

This is where you can really see the rust color splatter

It’s only been a week, or at least I think so, so it’s almost hard to see it unless your looking (the engine is a little dirty). I know it’s hard to tell but from what you can see do you think that the EGR cooler has a leak and it is dripping from the EGR temp sensor or cooler/EGR connection? My SCT tuner of coarse shuts off the EGR above idle. I didn't think so but could that somehow cause this?

Last question is: if the coolers or EGR are bad or are going bad and I need to replace the whole thing, has there been any body that have discovered any disadvantages of putting on a EGR delete/blow by kit since the tuner shuts the EGR off anyway.
Again my warranty is shot with the DPF missing so I wanted to see if I could get a heads up from you guys before I took it in. Just noticed it tonight so will try to get it in first thing. Also, I have been getting my oil tested and have the reports with each change. Is there something I could look for specifically that would hint that coolant has seeped inside the engine?
Again thank you VERY much for any help!!

 

Why do you keep thinking your warranty is so shot? if you are still under warranty and feel your dealer may give you a hard time, some do some done, just put the truck back to stock and go.

 

True but that is not what I was asking. The reason I started the thread has nothing to do with the warranty really. Only that it's now void because of the few mods I decided to put on the truck. Besides the fact that I have half of a bad conscious when I do something that voids something else then turn around and act dumb when i say "Oh, nope. I did nothing to something. I'm still covered right?". I'm taking it in whether I get it warrantied or not. That's reason number one. Reason number two is that I take my truck to a local diesel shop that voids warranties all the time and defiantly trust them way more then the lying dummies at the dealership service department here. I used to deal with the dealership all the time but every time i left i felt sore, alone, and heart broken... anyway that's the reason i asked about the delete/block off kit instead of having them install a new cooler and or valve. Might as well void the warranty even more. if that can be done

 

real quick i want to apologies if that came off as a bit condescending. i re read it after i posted it and it sounded like it to me. so i'll catch it before anyone thinks that.

 

I understand and respect your point of view. Regarding your question. Sorry, I just am not the right person to know. However, I have not heard many good results with any EGR delete or block off kits.

 

that's what i was wondering. i have heard mix reviews on them. some said they were great but had only had them for a few months. not long enough to really see the bad stuff. i've also seen people say they have had them for awhile with no problem. don't want this to happen again but don't want to add a mod that will make it worse either

 

I would wipe the area clean and fill the degas bottle. mark a line on the bottle.

Drive and check. See what you come up with.

EGR/Coolers would still be under warranty imho. I'd have them pressure test the system.

It is probably the valve.

 

Like I said ill get it fixed with or without the warranty but you think its covered?? I guess I understood that everything on the truck was void because of the dpf. If that's not true then again that's another reason to why I dislike my shop. But thanks for suggestion.you think its the EGR valve itself? If it is, other then the valve completelty going capoot what all could it harm and what else should I dig in and check for while cleaning and rechecking?

 

Alot depend upon your service dealer when we talk about warranty's.

It is part of the emissions system and part of the motor so technically it is under warranty. This also depends upon how it is viewed since you have a tuner.

In my eyes your dpf missing has nothing to do with a failer EGR valve or coolers (if that is the true leak). That is me.

As far as anthing else that should be done...nothing except the repair. You will most likely have to get a new valve and the housing it sits in...they usually break trying to get the valve out.

Be aware if you do this yourself that the new valve deletes the coolant line to it to prevent this in the future.

But lets not get ahead of ourselves, clean the area and see what you see first.

I cleaned it up and filled the bottle and will keep an eye on it the next few days. Updates to come. Here’s a new concern I found while filling the bottle. My fuel coolant resolver was really low too. I check it whenever I check everything else and didn't think it was low before. But I filled it as well and will keep an eye on it. Has anyone heard of any problems with these? And into the fuel would be the reasonable answer but if it’s not external where else could it go and harm it could cause? <o></o>
senix you mentioned if I have to replace the valve myself. If I do have to replace anything I’m thinking I will replace it with a delete kit. IMHO EGR's are no where efficient for diesels. But would put a stock EGR back on I guess if it’s just going cause more problems down the road. Anyone with the delete please chime in. <o></o>

Fuel cooler needs some attention on mine once in a awhile as well. The engine bay gets mightly hot. I tend to think an oz or two a year is no big deal.

My oil analysis indicate no concern.

 

Maybe I should check my fuel cooler too. I never even opened it! Is there a fill level indicator in there? I always check my degas bottle because ever since i had my cab off they must have not put a hose clamp in right becuase i see coolant on the frame rail. However, its a very slow leak and not worth my time to bring to the dealer. Maybe drop 1-2mm in 5 months. But i am curious now about my fuel cooler, never thought to check it.

 

There is a sight guage on the front of the resovoir. I checked and it takes the same coolant. It sets just behind the degas bottle. Where is it leaking on the frame rail? Depending where but when I checked on the common places for them to leak was on the frame in the wheel wale. I'm sure there are more knowlegable people on here about the issue though that will chime in

 

Thanks, I will check now while the truck is still cold..

I have a leak because i had a ****ty dealer take my cab off to repair stuff. They were very sloppy. Forgot to connect some sensors, did not clamp on some hoses right, had leaks on a few things, but the one they could not spot was this one. It wets the frame rail on the driver side right in front of the axle behind the front driver wheel. Will never go back to that dealer again.

 

Good idea! I'd be ok with with one hose. Mistakes happen but a few plus sensors. That is ***ty
