Your 6.7 Powerstroke's EGR cooler is leaking coolant into the exhaust stream, and the soot is gumming up the valve and turbo behind it. We replace the cooler and valve and clean the VGT mechanism, at your home, one visit.
The 6.7 Powerstroke's EGR cooler lives a brutal life: it takes exhaust gas at hundreds of degrees and chills it with engine coolant, cycling between extremes every single drive. Eventually the internal core cracks from thermal fatigue. Coolant seeps into the exhaust side, that's your white or grey smoke, and the coolant level starts dropping with nothing visible underneath the truck.
The failure doesn't stay contained. A leaking cooler changes how the EGR system flows, and the soot-heavy exhaust gas starts caking onto the EGR valve until it sticks. Then the same soot fouls the variable-geometry mechanism in the turbo, the little vanes that control boost. A sticking VGT is why so many of these trucks get diagnosed as needing a full turbo when they don't.
That misdiagnosis is the expensive trap with this engine. Low power, limp mode, and rough idle all point at the turbo, and plenty of owners have paid for one only to have the symptoms come back, because the actual problem was the EGR cooler upstream feeding it garbage. The right fix is the cooler and valve replaced together, with the VGT mechanism properly cleaned and verified, so you're not buying a turbo you don't need.

EGR Cooler & Valve Replacement with VGT Turbo Cleaning is a big job and shops quote $3,500–$5,500 for it. The single most valuable thing you can do before committing that is have the diagnosis confirmed independently, $100–$250 flat, at your location, no hoist needed, because a diagnosis isn't the repair. Plenty of cars arrive at that quote and turn out to need the smaller version of the problem.
And the honest scoping condition, up front: once I've seen it, I tell you straight whether it's something I can do at your place. If it needs a hoist, a press or a machine shop, I say so and point you to someone who has one. I don't take a job and figure it out in your driveway. That's the whole deal, and it's why the diagnosis comes first.

A leaking EGR cooler is steadily feeding coolant through your exhaust and aftertreatment system, and steadily losing the coolant your engine needs. Let it run and you risk two expensive outcomes: an overheat event that takes head gaskets with it, or a soot-jammed VGT that turns a cleaning into a full turbo replacement. The job grows roughly a thousand dollars at a time the longer the cooler leaks.
Yes. EGR cooler, valve, and VGT cleaning on the 6.7 are all engine-in-truck repairs. One full day at your driveway with level parking. We bring everything including coolant and take the old parts and fluid away.
Dealer pricing stacks book hours at their rate on top of list-price parts, and many quotes bundle in a new turbo because a soot-stuck VGT looks like a dead turbo on a quick diagnosis. We diagnose first, then give you one flat price for the complete job before we start. If the turbo itself is genuinely worn, we'll show you the evidence, not just a line on an estimate.
Usually not. On 2011–2019 6.7s, low boost and limp mode are most often a soot-fouled VGT mechanism or sticking actuator, both fixable without replacing the turbo. We physically check shaft play and vane movement and tell you straight which side of the line your truck is on.
No, emissions deletes are illegal in Ontario and we don't do them, full stop. The honest alternative is a quality replacement cooler and a clean system, which is exactly what this job is. A healthy EGR system on a stock 6.7 lasts a long time.
