Guys, I researched pretty well, I think I am fine but wanted input to kind of put it all to rest, if need be.

Been travelling back and forth alot from the desert floor to the Arizona mountains around 9100 feet altitude. We are getting into summer pretty well so pretty good contrast in ambient temps. Due to finally getting a Scangauge2, I am more aware of what is happening on the truck.

Today I had a few issues coming down to the hot desert. Saw EOT on a good hot climb of 236, ECT was 222, ambient temp was 87F, about 5200 foot elevation. From what I have read, no real biggie on the EOT value?

Later, about 2500 feet, 101F temp, small climb, 2200 or so rpms, 222/210, started what I think is turbo farting ("chuff, chuff, chuff"), just minor climbs...have not had that for 2 years or so. No codes thrown. I read where turbo farting is "normal"...but I didn't care for it last time around, after a bunch of tries we got rid of it after turbo cleaned, EGR cleaned, baro sensor replaced...not sure really which fixed it but it stopped.

So to repeat, sorry so long winded:

1. 236 EOT too high?

2. Turbo farting "normal"? Possibly solved with EGR valve cleanup? (have not done it for like 20,000 miles but have been driving it hard for several months).

Thanks fellas, great site, for a non mechanic, this place is a life saver.

 

So I hate to beg, but is there any straightforward way to deal with a turbo fart situation? Did it just occur due to pulling a small trailer in hot weather?

Is 236 EOT too high?

Thanks for any help.

 

I wouldn't worry about the oil temp under those conditions.

Was the turbo fart occurring while you still had your foot in the pedal, or only when you let off?

 

I was accelerating up a modest hill, foot on the pedal. Pulling only about 4000 lb trailer.

 

From my understanding turbo fart only happens if your on the pedal an let off of it all of a sudden. Atleast that's the only time my truck does it.

 

Same here.... only when I am honking on the throttle and then let off quick. It does seem to get a little worse with a dirty/plugged air filter though. I notice it less with a new/clean air filter.

I have never had it make "the fart" while my foot was down on the throttle. Just a thought but maybe start small and check your Cac Boots and make sure everything is still on good and tight and no cracks/leaks?

 

Thanks guys, good advice on the boots.

My foot never let up on the pedal. It just "puffed" like 3 times on 2 different modest inclines. Air filter is pretty new, no codes thrown, not making oil, last UOA was fine, new t-stat, no real problems I can think of...mpgs around 18.4 on these trips. Surprised me truthfully, been feeling good about things but not freaking out now either.

I just didn't care for it when it did this around 75k miles. As I said before, cleaned the EGR valve, replaced the baro sensor, cleaned the turbo, suddenly it resolved and didn't do it anymore. Which of the above solved it, I don't know.

Can someone explain exactly what is happening when turbo farting occurs?

Thanks again....
