2007 International 4400 Various Issues

Good afternoon forum.

This is an odd truck to place. Too large for the pickup forums, likely too small for the semi forums.

I purchased this truck recently and it drives and runs fine, but it generated a code on the way home from the sellers location (a 70 mile drive), so I dropped it by the dealer to read the code. I don't have the odd circular OBD reader connector International uses. I'm guessing proprietary data stream. If there's a consumer level reader available, I'm open for information.

The code ended up being a physically broken exhaust pressure sensor. They charged me $125/hr. to diagnose the issue and $125 for the sensor. Both seem high, but I wouldn't know where to start to troubleshoot without the codes. There was no indication of an issue. I suspect the sensor is in a spot that someone crawling on/over the engine could step on it and break it. Likely not intending to say anything. I'm not sure why the system needs to know what the exhaust back pressure is. Maybe to determine bad/stuck turbo or clogged exhaust? So it doesn't damage an exhaust valve?

While I was under the hood, performing a more thorough investigation of my newly acquired truck, I also noticed excessive oil in the coolant reservoir. That was a red flag to me, but not knowing International or the DT466 engine, I didn't know for sure. It drove fine on the way home and oil temp and engine temp were exactly as expected and this was in Southern LA (not L.A.) summer heat. I asked the dealer and he suspects a problem with the oil cooler. I would have guessed that as a "best case" scenario. "Worse case" scenario would be cracked head or blown head gasket. The oil, although dirty, shows no signs of coolant and is the correct color and consistency. I suggested to them that part of the process would be changing the oil simply because if oil is getting in the coolant, certainly the reverse is happening. The put a price together and came up with $2800. That includes new cooler, seals, gaskets, coolant, flush, oil, oil filter and labor. Again, seems high to me, but I'm not used to dealing with this size of a truck.

Thoughts on the issues?

Thanks.

 

Thanks for the comment so far. Good info...

Funny thing... the wording on the cruise buttons are rubbed off. I Googled for some images of the buttons, but haven't found any that match the layout yet. I was on the Interstate coming home and I was pushing the buttons expecting the On/Off button to be somewhere on the left and the Set/Resume button to be on the right. I eventually found a combination that allowed me to use cruise (which was nice), but not before finding that the far left button is the horn. I have dual air horns and I must have scared the crap out of the guy in the lane next to me (as well as myself).

This is the closest, but I have another button on the right. Not sure what for...

It will be more than a simple cooler replacement. Flushing the system (several times) to get all the oil out of the lines is going to be a task. Soaking my reservoir in solvent, as well as any hoses I can remove, is going to be a task. Looking on eBay for replacement coolers isn't working as expected. It keeps bringing up finned oil pan coolers (at least that's what it looks like). The dealer said it should be a "regular" looking radiator on the passenger side of the engine under the turbo. I'll dig around this weekend and make some determinations. It may be worth the $2800 if half that cost is parts. Cleaning this out would be hours of work.

Others to respond or other codes to trigger?

 

Thanks. I'm used to driving F450/F550's, but this is a different ride. Much heavier feeling. I haven't pulled a load yet, so that should prove it's value.

This is the one I'm leaning towards: Xtuner OBD2 CVD-9 Diesel Truck Diagnostic Scanner Android Bluetooth Heavy Duty 6919609544140 | eBay
Any thoughts on whether it will work?

I bought an inexpensive Android head unit as the original Kenwood/International radio was pretty much unusable. The new unit has some nice features: backup camera, GPS and Bluetooth for the code scanner.

It ended up being $100 for the part and $125/hr labor. The labor included reading the code, finding the part and replacing the sensor. Do you think the $2800 is a "deal" for what needs to be done to get the cooling system purged? Parts and labor.

As I was explaining to my wife what the issue was, I thought about the same point, the coolant shouldn't be able to push past the oil. Seepage is a possibility, but that would likely burn up as soon as the engine warmed up.

Yeah, I expect 100 flushes wouldn't get it all. Too many nooks and crannies and oil can be quite persistent. My trucks cooling system will be like a 70 year old's circulatory system... got a little plaque build in in the veins, but still flowing enough to keep things running.

 

Yes it does. Assuming you don't work for the International dealer service department...

 

Okay, so I finally received my package and the seller ended up substituting a CVD-16 for the CVD-9 I ordered. He insisted it was "better", but required an adapter cable to convert OBD to "Dutch". Now it sticks way down from the dash as the Dutch plug faces straight down at the bottom edge of the dash.

My thoughts on the CVD-16 so far: Chinese data mining to the max. When you install the app, it requests all kinds of crazy permissions not necessary to manage OBD functions. If you deny the request, the app exits. I dug out an old Android tablet, reset it to factory defaults (i.e. erase any personal data) and installed the app. Gave it access to my personal data and it opened cleanly. The adapter connected with minimal issue via Bluetooth. No password required, which is always an annoyance with Bluetooth since the password is almost always 0000 or 1234. What's the point? I clicked on the "truck icon" in the app and it said I needed to download another program. So the app on the Play Store is like a loader for the real app. Weird and unnecessary (except to elicit further data entry). I downloaded the secondary app and finally got it to open only to be presented with a serial number/password screen. I entered my serial number, but had no password. Fortunately there was a "forgot password" link. Unfortunately it didn't do anything. No action resulted in clicking it. Not even an error. I did some research on the Idutex website and realized the piece of paper with my CVD-16 was actually a small envelope that contained a password. I entered the password and progressed further. Finally, when I clicked the "connect to vehicle" icon, it pops up a small dialog window stating "Inspection permit... please wait...". After about 45 seconds it times out and states "Authorization failed". I'm not sure what it's trying to do or what personal data it is trying to send to China, but I can't seem to get past it and the Idutex website search doesn't result in anything useful. I'm waiting for the guy I bought it from to respond back.

More to come...

 

On another note, I'd like to add an EGT gauge to my factory dash cluster. There are 2 open areas for additional gauges in my factory cluster, so it could be a clean install if I can find the right size gauge with the correct colors and font. Any suggestions for gauge options?

 

The guy never responded to several emails through eBay, so I requested a return.

Next thing I'll try is using his OBD to Dutch adapter and a regular ELM327 OBD reader. Not sure if it will speak the right language (it should as I've always understood OBD was a mandated standard), but if that works, I'm golden.
