Understand what is going on in your $11,000.00 motor stock.
1, Regen process, add fuel on the exahust stroke to clean the exahust filters, this washes the cylinders down with fuel and leaks into the crankcase... Fuel in oil = Bad
2. Regen fueling cause bad fuel mileage, if yoru not burning it to create power it is being wasted. Heat is energy and it shoudl be used to push on the pistorns not to clean the filters.
3. EGR, this is a dumb idea from the getgo. Look at Eric's latest thread for the pictures. That should say it all. The EGR dumps hot gases and soot back into the intake (So why exactly do we have air filters again?) which ends up being a gritty tar like substance. Don't believe the pictures, take the intake elbow off....
4. Heat is the enemy of a turbo charger, regen up the exahust temps to something like 1500 degrees...... that can't be good for a oil lubricated bushing in the turbo.
5. Exahust temps under the truck are hot enough to start a fair if parked in the tall grass. Result burning your truck tot he ground and causing a field fire that you are responsible for.
You paid $XX,XXX.XX for yoru rig, with all the above equipment on it you shoudl get something like 100,000 mile out of it maybe. If that is the case why does Ford not warentee the power train for 100,000 mile any more?
My 99 7.3 lasted 520,000 miles before I traded it for a 05 6.0, which went 125,000, before a laundry list of probelms began.
My 08 is deleted and I expect it to last well over 200,000 miles it is called ROI in the financial world....
Good luck with your argument.
Any doubt on what i've said talk to a performance guy like Eric, Nate, Aaron, etc. Pull the intake elbow and see for yourself. then take a look down the intake of your car/bike/lawn mower.......
Key to a long life of a diesel engine, Clean Air, Clean Fuel, Clean Oil, keep EGT within limits and let 'er cool down before shutting off, and let 'er warm up before jumping on the loud peddel.
