Question pulled my egr valve

Well I pulled my EGR valve to clean it and noticed that has some damn areas on it. I was just out driving right before I pulled it. Dont know if that has anything to do with it but I am looking for some opinions on if there looks like I have any bigger issues with the buildup that is on it. It was cleaned less than 15000 miles ago also by ford when I had idling problems.






Right now Im going to clean it with some carb cleaner and reinstall and figure out from there based on some opinions if I have bigger issues. Right now I am having a random rough idle that only happens once or twice when driving and only happens randomly sometimes can go an entire week without it happening. From what I have been told by other people it could be chunks of carbon buildup breaking off from inside my intake manifold and being caught in the valve causing monentary issues that go away.

bigger issue is to look into the opening where the valve came out, look to see if it too is wet and goooey. If so bullet proof diesel is waiting for your call. (park the truck nose down for the night prior to looking inside.)

So I have some pictures now of the inside of the intake manifold where the valve drops in. It doesnt look good for me or my wallet right now

Here are the pictures. And as suggested I will park the truck nose down in the driveway tonight and see how bad it really is in the morning when I wake up but seems to be dampness in there now.

Looks like you probably have a blown EGR cooler.

I took mine out after 89000 miles and it did not look that bad at all. I would like to know what you find out. I am thinking the EGR is no good but just a guess.

That wet and gooey crud looks more like an issue w/ combustion efficiency, not so much coolant related.

Do much idling? Do you use a cetane boost fuel additive (good idea IMO)?

Personally I would replace the valve - since Ford upgraded the valve icomponents n 08 or so. $160 at TousleyFordParts.

I dont idle hardly at all actually just at stop lights when I am out driving I am very conscience to not let the truck sit and idle as it will cause carbon buildup issues. I use the Power Service Diesel Kleen Grey Bottle at every fill up. I will probably end up taking it to the local ford dealer as I have an extended warranty on the truck still and my deductible for it is only 100. And see what they say. If it is an EGR blown issue they are mod friendly and would allow me to delete it. I have already had that discussion with them before and they would not have an issue with it, they didnt even blink an eye when I came in with my SCT hooked up and had all sorts of warranty work done and have been working on the truck since I bought it at 74000 miles.
