TSB 08-28-1 and hesitation in rainy weather
 

Anyone heard of this? My truce experiences this in rainy weather. I went with a Bank CIA and no improvement. I've also seen where many other 6.4 owners have had the same issue. Could it be this is the fix we've been looking for? Please let me know your thoughts and if you have completed this TSB and with what results.

bump, i'd like to know about this too.

look at my latest post under the "anyone else" thread I would have sent the link but im not familiar with the site good enough yet

The TSB in question is actually 08-25-1 (6.4L DIESEL - WHITE SMOKE IN DAMP WEATHER CONDITIONS WHEN ACCELERATING - VEHICLES BUILT BEFORE 10/1/2008). This TSB applies to vehicles that experience significant amounts of white smoke under heavy acceleration in high humidity or rainy conditions. Hesitation as a symptom is not mentioned anywhere in the TSB...

That not the TSB # on my paper work its 08 28 1

Must be a typo as 08-28-1 does not exist...

Git r dun................
I had the same problem and I had my mechanic pull up that TSB and they changed the charged air cooler (intercooler) and the new unit work great. I have not had any white/gray smoke or hesitation while trying to accelerate while it has been raining./><o:p></o:p>

What is the TSB number they told you? Originally I thought water was getting into the Intake but this is not the case. This morning it was 90% humidity but not rain. Even without any rain but with high humidity my truck still hesitated. No smoke but hesitated almost everytime so water in the intake is not the issue. I even took the top off the intake and still had the same problem. I think this intercooler thing just may be the issue so i would like to know for sure what the TSB number is.

Thanks,

It is TSB 08-25-1. send me a PM with your email address and I will send it to you.

Can you please email me the attachment?

By the way, did your truck hesitate too or just white smoke?

My truck did both,when the moisture was high or when it was raining.

Just called and made an appointment for next Tue. Thanks again for everyones help and looking forward to the fix.

My diesel tech and the shop manager at the local dealer just ordered the new intercooler for me. All I had to do was mention the new TSB and they jumped right on it. Can't wait to be able to maintain speed up hills without the dash rattling like crazy. (in the rain)
