Coolant causing smoke??

[HiTechRedneck]

Still smokin'. We put an AFE air filter on and a Banks exhaust system. All of the sudden we noticed smoke. We took our 05' Excursion down to the shop to run diagnostics on it and of course the scanner won't go that high on this year yet. Put stock stuff back on and still smokin'. We are thinkin' it's coolant because it is dissipating so quickly. Another guy that works in the shop said he heard that a couple other guys are havin' trouble with the same issue. Anyone heard anything about this problem on ANY of the 6.0L's? We are startin' to hear that it's not just on the Excursions that this is happening. Thanks for anyones' input.......

yes i have heard about it. mine started to dry out on but now has stopped(for now). im not sure what is doin it since you havent said anything about having a programmer, that is what did it to mine. i have heard that aftermarket intakes and filters can let to much dirt into the turbo and engine and can hurt it, maybe it might have something to do with it. i dont think the exhaust would be the problem. but the best i can give would be to go to the dealership and have them check it out.

I can't fathom the afe kit having anything to do with the smoke, since i've heard from so many that it's the best on the market. But anything can be possible. Perhaps ford should investigate this further and maybe issue a recall if enough trucks have this problem. Good luck and keep us posted!

Yeah I'm with the others on this one HiTech, I'd let the dealer hunt it down. If you've removed the mods and it's still smoking, let the dealer solve the problem because it appears it's nothing you've done. I hate to see that you're having problems but hopefully it's something simple. Let us know!!!

Calling dealer today, hopefully we can get this resolved without problems. I will keep everyone posted on the outcome.

I remember reading about an exhaust gas cooler for the flow into the EGR valve. You guys will have to educate me on this. I wonder if they have problems with it. If it has an internal coolant leak, I would expect smoke at startup after sitting for a while, or maybe combustion gasses in the coolant.

We have a "little bit" of an update on this.....A really nice guy from the dealership where my husbands' shop orders Ford parts from, went out on a "test drive" from the dealership and dropped by the shop real quick. He looked at it and said he'd update some stuff with the computer and the EGR that should fix the check engine light and fix a valve issue that is happening because the EGR isn't sensing things correctly. He is their top guy for the heavy diesels and said he believes this will correct the problem and he'll do it under warranty. He said this is a fairly common issue with this engine when you put a new exhaust system on and add an air filter kit because the computer isn't sensing enough back pressure so it throws a code.

I'll keep everyone posted when we get final results. He said if that doesn't work, he'll flash the computer. We are setting an appointment up some time next week so hopefully we'll all have an answer soon!

Thank you to everyone who has been trying to help us!!!!!!

My buddy's 04 seems to have the same problem with his check engine light coming on claiming too much backpressure. He put an intake on it and cut out all the restrictions in his otherwise factory exhaust. Perhaps I can reccomend he do the same to correct that annoying problem! Thanks Red..

Thanks. We're hoping it will be that easy!!

Good deal! I hope that's all it is and I hope you get as much fun out of your PSD as the rest of us!
