Fixing CCV Issues: Crankcase Filter Delete 6. 7 Cummins
In case you're tired of since "service perform" message on your dash, a crankcase filter delete 6. seven Cummins might be exactly what you're looking regarding. It's one associated with those modifications that many diesel owners eventually stumble upon right after getting frustrated along with the high cost of routine maintenance or, worse, finding a pool of oil sitting in their own turbo compressor casing. The 6. seven Cummins is the workhorse, certainly about it, but the particular way it manages crankcase pressure through the factory leaves a lot to become desired.
For those who aren't familiar along with the technical headaches, the stock setup uses a closed crankcase ventilation (CCV) system. Basically, as the particular engine runs, stress builds up in the crankcase. That pressure contains oil air and blow-by gases. Instead of just venting that stuff into the atmosphere like the old 5. 9 Cummins i did so, the 6. 7 routes it back in to the consumption. The idea would be to burn those vapors off for exhausts reasons, but within practice, it just eventually ends up coating your own turbo, intercooler, and boots in the thick layer of oily grime.
Why People Make the Switch
The main reason most guys look into a crankcase filter delete 6. seven Cummins is to stop the "oiling" associated with the intake tract. When you pull off your intake horn or look from the cold-side intercooler boots on the high-mileage truck, they're generally soaked. This oil doesn't just sit down there; it degrades the rubber boots over time, which makes them soft and vulnerable to blowing off below boost. It also coats the intercooler fins, which may actually hurt your cooling efficiency more than the long carry.
Then there's the filter alone. That big rectangle-shaped box sitting upon top of your own valve cover isn't cheap. Depending on where you purchase it, you're taking a look at a chunk of change every 67, 500 miles—or quicker if your vehicle sees a great deal of idle period. By deleting the filter, you're basically removing an upkeep item and the potential point associated with failure. If that will filter gets completely clogged and a person ignore the warning lights, the pressure has to proceed somewhere. Usually, that "somewhere" is by means of your rear primary seal or additional gaskets, which is a significantly more expensive repair than an easy delete kit.
The way the Delete Really Works
Whenever you decide to go through with a crankcase filter delete 6. 7 Cummins , you're essentially switching the system through a "closed" cycle to an "open" loop. Most kits come with a few basic parts: a block-off plate for the intake connection and the new breather set up for the valve cover up.
You'll remove that bulky factory filter element and replace it along with a plate or a specialized cover. Instead of the blow-by gases being sucked back into the particular turbo, they get routed through the hose. Most people run this line down the side of the motor and vent this toward the surface, much like the "puke tubes" upon the older 12-valve and 24-valve motors.
It's a simple mechanical fix. No more oil in the particular turbo, forget about expensive filters to purchase, plus the engine reaches breathe a lot easier. You might discover a slight "diesel smell" standing close to the truck at a red light, but for most Cummins owners, that's just the smell of the healthy engine.
The Messy Reality of the Share Filter
If you've ever taken apart a six. 7 Cummins along with 100k miles on it that nevertheless has the share CCV setup, you know how nasty this gets. The essential oil mist mixes with the soot coming through the EGR control device (if that's still intact) and generates a thick, black sludge. This sludge builds up on the grid heater and the intake valves.
By performing the crankcase filter delete 6. 7 Cummins , you're cutting off half of that will equation. Even if you're running a totally stock emissions setup otherwise, keeping that will oil from the intake is a massive win for the particular longevity of the engine. It keeps the MAP sensor cleaner, which means the particular ECM gets much better readings as well as the truck runs smoother. It's a small change that has a huge "trickle-down" impact on the relaxation of the engine's health.
Installation Tips and Tricks
Installing the delete kit isn't exactly rocket technology, but there are some issues to keep in mind so that you don't end up along with chaos on your own driveway. First off, make sure your vent hose is routed correctly. You desire it to get a nice, downward slope without any "dips" or "traps. " If essential oil collects in the low spot in the hose, this can freeze during winter or just obstruct the airflow, which usually builds up pressure back in the engine.
Another thing to think about is the hose length. You want it long enough in order to vent underneath the truck so the oily mist doesn't layer your front axle or suspension components, but not so long that it will get caught in the drive shaft or melted on the exhaust. Zip ties are your best friend here. Safe that line nicely, and you'll not have to think about it again.
Dealing with the particular Dash Lights
Now, here is usually where it will get a little tricky for some folks. The particular truck's computer needs to see that filter there. Depending on the year of your own truck and the particular specific kit you buy, you might get a "Service Perform" light or a "Crankcase Filter Full" message even after you've installed the particular delete.
Most high-quality crankcase filter delete 6. seven Cummins kits include a way to trick the messfühler or a plug that handles the electronics. If you're managing a tuner, a person can often just clear the upkeep reminder or switch off the supervising for that particular sensor. If you're doing this on a totally stock pickup truck without a tuner, just be ready to do a regular reset from the support light (the old "brake and fuel pedal" dance) in order to keep the marks at bay.
Could it be Worth This?
From the natural mechanical standpoint, the answer is almost always yes. Any kind of time you may prevent dirty, warm oil from getting into your turbocharger, you're doing the machine a favor. Turbos are precision devices that spin with incredibly high RPMs; they don't specifically love being covered in crankcase gunk.
The particular only real downside is the environmental aspect—which is why these products are usually labeled for "off-road use only"—and the casual drip associated with oil on your driveway if the motor has a large amount of blow-by. But honestly, compared to the cost of an offered turbo or even a seeping rear main seal off because of a clogged filter, the little drip associated with oil is a little price to pay for.
Final Thoughts
At the end of the day time, a crankcase filter delete 6. 7 Cummins is definitely one of individuals "set it and forget it" mods. It simplifies the particular engine bay, will save you money on filters every year, plus keeps your intake tract resembling it did the morning this rolled from the set up line.
If you're someone who plans on keeping your Joker Ram for the long haul, getting care of the particular CCV system is usually just part associated with the deal. Whether or not you go along with a basic vent-to-atmosphere kit or perhaps a more complex catch can setup, getting free of that manufacturing plant filter is really a solid move for anybody who actually uses their truck for actual work. Just get a basic tool set, a Weekend morning, and you can get this project knocked out prior to lunch. Your turbocharged will definitely thank you for it.
