NOISE AND HIGH EGT'S

[justa08powersrtroke]

Ok my 08 has 10,000 miles on it and now it's making the tapping sound and at full throttle the egt's get up to 1250 and the turbo's stop spinning like it's on a limiter. this is before the truck gets up to 60 mph. Has anyone else had this problem? The only thing that I have done that I thought started the problem is in a regen I shut the truck off not thinking about it. oppps on me now this is my problem.

Also wanted to add that the engine temp and trans temp are normal during this. Is it possible that the exhaust is clogged

Shutting down once during a regen shouldn't cause this. I have had to do that a couple of times in the past.

My dealer mentioned they have had a few trucks in with DPF failures so its a possibility.

I agree, shutting down is not a problem. Regen will continue on the next run as needed. I've done it with no problems, and hardly notice that I'm in regen if it wasn't for the the drop in mpg' while on the highway or the high idling while in park. Hope you get it figured out.

thanks for the feed back guys. I'm going to turn it back to a stalker and send her to the dealership. I'll tell the tale when they shine some light up my tailpipe

my INSIGHT tells me that my EGT's,while regening at a stop are around 750. That is way above the " suggested safe 375-400 " required for shutdown. Is this an issue...or am I being anal?

[justa08powersrtroke]

Now my truck on regen at a stop last time was 900 - 1000. While driving my egt's were hitting 1250 - 1300. Whitch reminds me of the first time my truck went into regen I was sitting at a QT. And it got so hot I couldn't sit in the truck. Maybe mine has been f'ed since I bought it

[catdiezel]

sounds like a clogged DPF or a bad turbo that will for sure cause high egts'

[gonalez1]

how do you know when the truck is in regen?

Just a thought but have you checked all of you intercooler boots? Is your acceleration normal or sluggish?
