TSB 8-25-1 finally!

ctownson · #1 (**permalink**) 10-29-2009, 05:31 AM

After 2 trips to the dealer, and taking the tsb with me, they have finally agreed to replace the CAC and also ordered a new EGR at the same time. I was pretty insistent because this problem is one that is very dangerous in my opinion. Four times now, I have been pulling a trailer and have needed to accelerate (on an on-ramp, passing, etc.) and have had the problem of white smoke, loss of power, shaking, etc. One time this resulted in a near accident because of losing power and the engine stumbling. The tsb says nothing about losing power, but others seem to have experienced the same thing. Do others think this is a safety concern or is it just me?

I think it could be a safety issue in the right situation. My issue with the stumbling/stutter, etc... has mostly been when I get stuck in the left lane and I can't speed up in order to get out of the way, then the impatient morons start peeling around my right side and I sometimes have to "nudge" somebody off the road or into the far right lane in order to get out of the left lane. Don't get me wrong, I don't run people off the road but I do hate being passed on the right so I assert myself when the time is right to cut them off.

I was pulling about 8000 lbs and trying to merge onto an Interstate. I had plenty of room under normal conditions, but I was merging in front of an 18-wheeler. He was way back in my mirror but probably coming at 70mph. As I merged and hit the accelerator to increase speed, I saw a stream of white smoke coming out the exhaust and the truck would not pick up speed and started stumbling, etc. Now the 18 wheeler is getting close and he has to brake heavily to avoid hitting me in the rear. It certainly scared me and the truck driver was rightfully po'd!

Just one more thought - this problem is pretty random so you never know when it might happen and that can end up putting you in a risky situation. Under normal conditions, I hit the accelerator pulling 8000 lbs and take off - the truck pulls amazingly and has great acceleration even pulling a load. So, you get used to that and drive accordingly. Then, at some point you hit the accelerator and the dreaded problem occurs!

I had this same problem, and after taking it to the dealer with the TSB they told me they could not reproduce it. It was a sunny day. they called me and told me they couldnt get the truck to reproduce it and I informed them that they wouldnt be able to on a sunny, dry day. They wanted me to come show them. So I drove down there, and luckily a storm front had moved in. I was able to go out with the mechanic and reproduce it, and then, as he was looking at the TSB on the way back, he noticed on the TSB that it did not say that the dealer has to be able to reproduce the problem. It states that if a customer comes in with these complaints they are to replace the CAC, no questions asked. So I wasted my time, in a way. They replaced the CAC, and it hasnt done it again, but they said nothing about my EGR. I know several people have had the CAC replaced and have had the issue return. The new CAC looks to have wider fins. A picture of my new CAC is posted in my garage if anyone wants to see it. I hope, now that im over my 36,000 warranty, that my EGR doesnt start messing up. What would cause the EGR to be part of this problem possibly also?

ssharbor, your EGR system is covered under your 100,000 mile engine warranty. I wouldn't worry about it!

ctownson, I can understand where you're coming from. But, as a truck driver, a situation like yours doesn't aggravate us half as much as the clown merging on at 35 MPH and simply doesn't care enough to accelerate to highway speed in a reasonable timeframe.

At least you were trying!

Thanks Tom, and as for those people who dont understand what an on ramp is for, I wholeheartedly agree. Nothing gets me more than being behind someone who doesnt realize that they are supposed to accelerate so they can merge INTO traffic, not pull out into traffic THEN accelerate. I can appreciate your position too because you have alot of gears to go through if you cant avoid these people and all that momentum is lost. Makes you want to just smack them sometimes.

this is a safety issue and you both have done the right thing by insisting it get fixed. ssharber, at least now when you bring something to their attention they know that you are just not making something up.

I have a great relationship in that manner with my service advisor/diesel tech. Heck last time I dropped the truck off I gave the shuttle driver the keys and told him what the issue was.

It is amazing how some dealers need to be forced into doing TSb's.. We had the same issues. We explained them to our local dealer and they did the TSB. It was a remarkable improvement. We have a dealer both in Ohio and here in Florida aneverytime the truck is in for service they check for the latest updates and as me if i want then done...

ZeroOne · #10 (**permalink**) 10-29-2009, 10:57 AM

I agree with the safety issue. Nothing like pulling out onto a highway, only to fog the road (they can't see you beyond the cloud) and only be going 35mph on the other side! You're a sitting duck for getting rear ended.

On another note, anyone notice lower or slower to climb boost levels? Thats my only annoyance w/ this TSB.

ctownson · #11 (**permalink**) 10-29-2009, 11:12 AM

I have heard about the reduced boost after the tsb and I will let you know my impressions. About the EGR, once the mechanic agreed this tsb needed to be done his comment was that he might as well go ahead and order the egr in case in needed to be replaced also.

Its amazing how many people still don't understand that a TSB is NOT A RECALL! TSBs are informational only and may/may not refer to your vehicle.

I think what he really mean't is the that most dealers/service advisors may not be open to even exploring the possiblity that the TSB in question might apply.

About the slower boost climb, I do recall that issue when I got the new CAC. My "seat of the pants" feeling was that the boost felt like it got more grunt with less boost than before with the old CAC.

Lower/slower boost, more power to the ground is what I mean. Seemed like I though the new one was more productive. Been wrong before though! Here lately I have been driving around FL and I am feeling that the motor is getting swamped, seems sluggish. Is it the heat and humidity? It's really hot outside.

About the cooperation with TSB's, it's terrible almost everywhere. The folks at the service desk have to be schooled 6.4 techs and also the diesel tech in the garage needs to be schooled. Then, both (all) parties need to be disciplined enough to go to their service updates regularly. Otherwise, most of them don't know about the new TSB's or any other info. My diesel tech told me that he neglected to get his updates on his laptop for several months. Kinda drives me crazy but he's a cool guy.

Yeah, it turns out the new one is more restrictive, in an effort to increase the turbulence inside and break up any water headed for the intake. Boost levels take a hit because the MAP is after the intercooler, and turbos before. Had mind done and was pretty pissed that they didn't redesign anything, but just put in restriction. Made a big fuss about it here:
