The main thing is to drive at constant freeway speed for 30-45min to get the DPF up to temp where it can burn off the soot. The SCR will also clear with heavy footed acceleration, once the DPF flows better.
Properly seating the two connectors likely solved the root issue(s). Try driving the truck out on the freeway to get your EGT up to where the DPF can burn off soot. Driving up into the mountains (if available) works, on the freeway towing a trailer, engaging "Tow/Haul" mode, or using the shift...
That looks like the vacuum pot controlling the EGR flow valve. You're right, the bushing in the eyelet has failed causing a lot of play. Looks to me like it's causing the valve to be open a little more than it should, allowing some extra exhaust gas into the intake.
Are you losing any coolant? If so, my thought process is: Cracked EGR cooler sends coolant through the crossover tube, steam cleaning it and the MAP sensor (and the intake manifold some). This causes bubbles in your cooling system, affecting the coolant bypass valve (on passenger frame rail...
Did you replace both o-rings on the little plastic crossover tube on the pump? When I replaced my water pump last August, I recall the main pump bolts get a thread sealant because they go into the water jacket, and a specific torque on the bolts.
FRavencroft: The software update came about from the common tone ring failures. Massive oil loss isn't necessarily associated with tone ring failure; It is, however located right there by the rear main so it's possible.
Another possibility for your situation could be related to the turbo oil...
Based on what the video shows, that looks like it could be tone ring failure (mounted between crank and flex plate) that damaged the sensor, which ended up "taking out" part of the aluminum pan up by the rear main bearing/seal.
If I might make a suggestion...
There is a one-piece replacement tube with braided hose section available. It looks to be significantly more durable, but the catch is getting the metal oil line out of the way for removal of the cooling line's turbo side banjo bolt. I had this done on my truck...
CVR_71,
It won't hurt to look under the HPFP cover. My first thought is: There's a fuel line coming off the bottom of the pump that goes to the driver's side fuel rail. That line is a single use item. The pump side of that tube has a crush type seal and it's possible the tech reused it or...
Tinker,
Some observations from my Ecodiesel ownership (168k mi and counting):
- I like and use Lucas products, BUT I have stopped using the fuel additive in my Ecodiesel (still use in gas engines). In short, the EGTs when driving are, apparently, frequently not high enough to fully burn the...
Another possibility is the EGR cooler has a crack and the coolant is leaking into the tube that goes to the intake. In this scenario, the coolant would be cycled through the engine in vapor form and out the tailpipe. Never to be seen on the dipstick or on the ground. Check if your truck has...
If the code is still popping up, the issue isn't fixed. If it is "lingering" in the permanent codes, but not an active code, then just needs to be driven for a few days until the computer can "see" the problem has been fixed and it will remove the code from the permanent list.
