Failing DPF? Here’s how to fix your truck
If you’ve ever had a limp home condition caused by a failed DPF or have experienced your truck locking you out from even starting it, you may have already learned what the DPF does and the kinds of issues that they can have.
If you haven’t yet had a problem and want to be prepared, or if you’re just naturally curious like me, keep reading.
What is a DPF system?
The DPF, or Diesel Particulate Filter, is the hardware in charge of the process of filtering the large exhaust gas particulates (soot) out of the exhaust.
Often internally constructed from cordierite, a material that is also used in the support structure of another type of automotive exhaust filter – catalytic converters. DPF filters have a honeycomb patterned chunk of this material stuffed in the middle of a steel canister, installed in line with the exhaust flow.
The system works by collecting the soot, trapping it in the honeycomb passageways as it flows through the filter. These systems do actually collect a ton of the particulates that diesels produce, which in turn equals cleaner air for everyone to breathe.
So, how could a system that obviously reduces emissions not be ideal? Well, the answer to that question brings to light the (literally) dirty downside of DPF systems:
The inherent design of a DPF system is to filter enough soot that it actually regularly becomes clogged.
I don’t have to tell any gear head how a clogged up exhaust system is ridiculously bad for an engine. Back-pressure and heat are the biggest enemies to your turbo diesel.
The solution for this clogging issue? Burn it with fire! Or with really, really high exhaust gas temperatures to be more accurate. This process of super heating the filter element is called a regen for short.
The methods used for this regenerative process vary depending on make and model, but the mainstream methods include late fuel injection, turbo boost changes, EGR valve changes and intake air throttling.
The diesel engines in most trucks use a variation of the late injection method, which injects fuel after the TDC stroke in order to heat up the exhaust gasses, and in turn, the DPF. This method has the potential to wreak havoc on your turbo seals, EGR system and lubrication system. Late injection forces fuel into the engine oil, raising your oil levels to a unhealthy level and destroying the oil lubrication potential.
Lower fuel mileage concerns
The late injection method is also pretty terrible for your fuel mileage, because not only is the computer dumping enough fuel through the engine to raise the combustion chamber temps high enough, engine cooling and other components are also affected by the heat, in turn decreasing your fuel economy.
In addition to all of the above pitfalls of engineering an effective DPF system, the regenerative process is actually incapable of keeping the filter 100% clean, which inevitably results in the filter clogging, exhaust backpressure skyrocketing, a wonderful limp home condition for the engine management system, and an expensive replacement or cleaning service (AKA the slow, painful death of your wallet.)
IF MY DPF FAILS, SHOULD I KEEP IT OR DELETE IT?
WELL, THAT DEPENDS. YOU ALWAYS HAVE TWO OPTIONS IF YOUR DPF FAILS: A DPF DELETE KIT, OR A NEW OEM DPF REPLACEMENT.
WE’LL CHECK OUT OPTION ONE FIRST. THIS WOULD APPLY IF YOU HAVE A TRUCK THAT IS ONLY USED OFF-ROAD, SUCH AS ON A TRACK OR A FARM, AS IT IS CURRENTLY AGAINST REGULATIONS TO OPERATE A VEHICLE MODIFIED LIKE THIS ON PUBLIC ROADS, AT LEAST IN THE U.S AND CANADA.
WHAT IS A DPF REMOVAL KIT?
I’VE OUTLINED THE THREE BASIC PARTS THAT MAKE UP A COMPLETE DPF REMOVAL KIT, USING THE TOP BRANDS IN EACH CATEGORY AND MADE TO FIT A CUMMINS, JUST AS AN EXAMPLE. IF YOU SCROLL EVEN FURTHER, NEAR THE BOTTOM I’VE NARROWED IT DOWN TO MODEL AND YEAR SPECIFIC COMPLETE KITS FOR WHATEVER TRUCK YOU MIGHT HAVE.
1. TUNER
THERE ARE ONLY A COUPLE OF TUNERS ON THE MARKET THAT ARE CAPABLE OF ELIMINATING THE CODES THAT WILL HAPPEN WHEN THE DPF IS REMOVED. THE GUIDE LISTED FOR YOUR MODEL TRUCK WILL GO INTO MORE DETAIL AS WHICH TUNER IS BEST FOR EACH APPLICATION.
2. DPF DELETE PIPE
THIS SEEMINGLY SIMPLE LOOKING PIECE OF PIPE IS A VITAL COMPONENT OF THE OVERALL DPF DELETE. THIS PIPE REPLACES THE LOST SECTION OF EXHAUST THAT HAS TO COME OUT WHEN THE DPF IS REMOVED. THERE ARE A FEW WAYS TO DO THIS DEPENDING ON WHICH TRUCK YOU HAVE. SOME CHOOSE TO REPLACE JUST THE DOWNPIPE SECTION THAT CONTAINS THE DPF, KEEPING THE FACTORY EXHAUST REAR SECTION (AND THE NOISE DOWN) WHILE OTHERS WANT TO HAVE THE MOST FREE-FLOWING EXHAUST POSSIBLE, AND FOR THAT YOU WOULD WANT A COMPLETE AFTERMARKET EXHAUST KIT FROM THE TURBO ALL THE WAY BACK.
3. EGR DELETE KIT
THE EGR BLOCKOFF KIT IS IMPORTANT IF YOU WANT THE MOST EFFICIENCY OUT OF YOUR DIESEL’S TUNE. ON SOME SETUPS, YOU CAN MANUALLY DISABLE THE SYSTEM BY DISASSEMBLING IT AND MODIFYING IT, FOLLOWED BY TUNING OUT THE CODES THAT THE ENGINE WILL THROW. A LOT OF TIMES IF YOU ARE GOING TO BE DISABLING THE SYSTEM ANYWAYS, I WOULD RECOMMEND TO JUST GO AHEAD WITH THE BLOCKOFF KIT. IT GETS RID OF A LOT OF UNNECESSARY PARTS UNDER THE HOOD AND MAKES THE ENGINE COMPARTMENT A LOT CLEANER AND SIMPLER.
OEM DPF REPLACEMENTS
THANKFULLY THERE IS A SECOND OPTION FOR TRUCKS THAT HAVE HAD THE DPF FILTER CLOG BEYOND WHAT THE REGEN CAN RECOVER FROM. IN THIS CASE, IT IS RECOMMENDED THAT THESE ROAD-GOING TRUCKS BE FITTED WITH AN OEM DPF REPLACEMENT FILTER, IN ORDER TO KEEP THEM ROAD LEGAL ACCORDING TO FEDERAL MANDATES.
IT CAN BE HARD TO SOURCE THE CORRECT PART NUMBERS FOR THESE OEM REPLACEMENTS AND ASIDE FROM GOING DIRECTLY TO THE DEALER (WHO MOST TIMES IS THE COSTLIEST OPTION,) YOU MIGHT NOT KNOW WHO TO BUY FROM. MY FAVORITE WAY TO ORDER ANY PARTS LATELY HAS BEEN GOING STRAIGHT TO AMAZON AND TYPING IN THE PART NUMBER, TO FIND WHAT I KNOW WILL BE THE CORRECT PART, AND THAT I KNOW WILL BE AT MY HOUSE IN A COUPLE DAYS.
THE ONLY DOWNSIDE TO THIS IS THE RESEARCH NEEDED TO FIND THE CORRECT PART NUMBER, WHICH CAN BE ANNOYING SOMETIMES. I’VE COMPILED THE CORRESPONDING PART NUMBERS WITH THE TRUCKS THEY GO WITH, IN SOME LINKS DOWN BELOW, IN CASE YOU WERE LOOKING FOR THE SAME REPLACEMENTS FOR YOUR TRUCK. SAVES ME FROM HAVING TO TYPE OUT AN EMAIL OR COMMENT EVERY TIME SOMEONE ASKS, NOT THAT I MIND TALKING TO YOU FOLKS!
