If it is belching pure white smoke that smells like diesel, it is a fuel problem. Sounds like a stuck or bad injector. Bad turbos usually make blue/oily smoke, or black with no boost. I'd try cracking injector lines, one at a time, and see if it goes away. If it goes away, you found the...

14.5 on winter blend, 17.5 on summer. This is average, no towing driving.

Talking to the maintenance supervisor, the insides are ceramic, and the outside shell is stainless. It is basically a hunk of ceramic in a metal tube.

I'd like to see it implemented. Though, I don't think you can do it with our ECM.

I can't say exactly for which company, but I can tell you that I do work for a company that makes catalytic converters and also DPFs, such as the ones on our trucks. The substrate inside is just ceramic in the "soot traps" that are on our trucks. They serve to afterburn, so to speak, the...

Just to continue on it, O2 sims are.... Legal to own. Illegal to use, buy, sell, or install. Now, for scientific research, if you look hard enough, you can find a schematic. At one time, I had made one from a PIC controller that even fooled the dealership computers. It was a one off...

I don't remember the link, but there is a link that if you send proof to Chevy, at 200k miles they send you a sticker, 300k you get something, and 400k you get something, and at 500k you get a super nice plaque.

When buying a used diesel, especially if it is your first, try to avoid buying one that does not run, even if the owner claims something simple, until you are experienced with diesels. Something that sounds like a simple problem can be expensive. When you are familiar with diesels, a problem...

For $220, I'd get a double flaring tool, tubing, fittings, and do it myself. Then spend the $150ish left on beer or something. Why go stainless? Regular steel will outlast 99% of the truck if it is a 95.

Well, it is gonna take a few weeks for it to show up on Yahoo, unless someone wants to donate cash to the cause, take it on themselves, and "Git-R-Dun". I did the free reference, but it takes a couple weeks for the servers to crawl it and show up. With all the MS-Yahoo stuff going on, you...

Turn off your headlights. I hear in the Honda Civic forums that it makes your car go faster, so I recon with a diesel it will get you better mpg. :D

Not much you can do with a diesel besides a clean air filter, tire pressures in spec, alignment, easy with the go pedal, don't use winter blend, and a tall gear ratio. I seem to stay around 17 mpg no matter what I do.

I had a CTS race me today. Sumbitch was fast.

I have an advertising idea I'm gonna try. We will see if it works or not.

This thread is started as a way to keep info clear and concise in checking a part on the 6.5 that you suspect is bad. 6.2/6.5 Glow Plug Controller (AKA Glow plug relay) Single big heavy red wire terminal - Should have battery voltage on it all the time. Double big heavy red wire...

Sticking IAC can do it, as EGR and a bunch of other things. Getting any codes?

Crack the vent on the fuel filter and with the lift pump running, see if you got fuel. If an armature is not pulled in a solenoid, very simply, it can't get rid of the magnetic flux, so it gets rid of the energy as heat. However, DC solenoids run hot. Have someone cycle the key on/off and...

Last time I 1/4 miled anything, it took me 23 minutes from a twisted drive shaft.

I have a Garmin Nuvi 260W and love it.

You pop up in my bathroom toilet, and I swear to god you are gettin' hit with a plunger. :D
