Make sure the scv connector is in good shape. Replace the whole pigtail if there's the tiniest doubt. If there's a momentary bad connection, it will go to max rail pressure and limp mode. This connector is not 100% problem proof. Make sure the fuel temp sensor is plugged in. It's easy to...

The compressor wheel splitting down the middle like that is from fatigue failure. The centripetal forces on the compressor wheel at full rpm are enormous, approaching aluminum's modulus of elasticity. Aluminum doesn't like having forces placed on it that are anywhere near approaching the point...

If you're familiar with the workings of DX, then DXII will come pretty easily. It's primary benefit, which you'll soon notice, is the ease of hopping between the separate modules on the truck instead of having to access each one separately (which takes forever). The interface tools (I use...

Some turbos tend to push a nominal amount of oil all the time. Not enough to affect oil consumption noticeably, but enough to always be present in the CAC and pipes. If one wanted to be super analytical about it, measurements of radial and axial endplay could be taken at regular intervals and...

Seems to me the selling dealer should be responsible, but I imagine that's going to be difficult to accomplish without pulling some teeth. Good luck!

You have to fix the ABS immediately. Without it, the torque converter unlocks. Allison does this to increase fluid flow to the cooler, but the cooler isn't big enough to handle the heat load of an unlocked converter, so the transmission overheats anyway. You can access the ABS and...

Check engine light on? Any other warning lights on? How does it run otherwise? Is there a large cloud of black smoke following you around, or any other weird symptoms? How long after you bought it did these symptoms develop? Was it a slow progression, or did it just stop working right all...

Our body guy is working on a hood from a 2006 268. As many of you know, all of the 6 cylinder trucks from 2005-2010 are prone to ridiculous cracks where the hood hinge attaches. I'm going to take pics of the process used to fix these cracks. This is something the average joe can do over a...

Other than underinflation, I have no idea. I Googled "rear duals scalloping" and found this article. What's Killing Your Tires? - Article - TruckingInfo.com

Check rail limiter for leakage. Try aux tank before condemning pump.

You may be right.

Unplug the scv snd try again. It will go to max fuel pressure.

It sometimes takes quite a bit of cranking to reprime. No more than a full minute, usually. If still no start, bypass the filter entirely and see if it will run off of an auxiliary fuel source. A 5 gallon can will work.

Use the middle one with the adapter that should have come with it. The left and middle ones are identical if you pull the tip off of the middle one. The tip and adapter plate make it adapt to your older model pump. The current short scv is ancient and immediately suspect. They don't even...

This is exactly what I was talking about. This seepage means the seals have hardened with age and heat cycling. Fine in cold weather, too brittle to seal air out when it's cold. Glad you found it, and I'm glad it was cheap!

Now, if there is coolant in the def tank, I'd blame the def tank sensor. But it sounds like a shop replaced a ton of unnecessary parts.

The two liquids, while close to each other in a couple of places, would have to travel through a significant amount of metal to mix. It's always human error, up to this point anyway.

Roger that. I pm'd you my cell #.

That's normal. It's got a variable nozzle turbo in it, and if the ECU decides it wants more boost, it can command the the turbo to spool up at any engine rpm.

It rubs the lotion on it's skin.
