'05 F250 6.0 78,000 miles 6 speed manual.
Recently installed an EGR delete kit consisting of an up-pipe block off and a coolant by-pass.
Symptoms prior to install: White smoke, loss of power, and coolant consumption. Stopped driving the truck to prevent further damage. Prior to that, no engine/turbo issues.
Do you think that just doing an egr cooler delete will fix this?
Did you address the plugged up oil cooler that is the underlying cause of the egr cooler failure? If not, your oil cooler will be the next thing to explode and that will fill the cooling system with oil.
Had removed turbo, intake, & other accessories. No damage to head gaskets/heads. Cleaned intake and EGR valve, did nothing to turbo. Reinstalled everything to proper specs. EGR valve in place and connected to wiring harness.
The failed egr cooler sent coolant through your turbo. Mix heat, soot and coolant in the same side of the turbo that houses the vanes that control boost will give you the symptoms you describe.
You need to take the turbo back off, split it and clean it.
Symptoms after install: Starts, idles, and drives normally aside from two things. No boost; lack of power especially above 2000 rpm. I have performed the re-learn process twice; with the engine at normal operating temperature. Only once did the turbo respond during test drive with a surge to 5 pounds while ascending a grade at 2200 rpm, third gear, struggling to maintain 40 mph. After which the gauge has remained at zero. While driving it sounds as if I'm hearing the turbo, but it definatly isn't making any boost.
Along with cleaning the turbo, there are a few other easy things to clean/check.
One of them is the rubber hose that comes off the top of the intake and goes toward the passenger side of the truck. Take the hose off the intake and the MAP sensor. Carefully check that hose for pinholes, nicks and tears. Blow it out with compressed air. Using an allen wrench close to the same diameter of the brass nipple on the intake that the hose connects to, poke the hole to make sure the cleaning done didn't plug the hole.
On the drivers side, connected at the same spot as the front FICM bracket at the valve cover, you will see a sensor sitting on top of a stainless steel tube. Use two wrenches and remove the sensor. Clean the bottom of the sensor with carb cleaner. Shoot brake cleaner down into the tube just to be sure the tube is not clogged. That tube just goes to the exhaust manifold, squirting cleaner down there won't hurt anything.
