Fixing CCV Issues: Crankcase Filter Delete 6. 7 Cummins
If you're tired associated with seeing that "service perform" message on your dash, a crankcase filter delete 6. 7 Cummins might be precisely what you're looking regarding. It's one of those modifications that most diesel owners eventually stumble upon right after getting frustrated with the high price of routine maintenance or, worse, finding a pool of oil sitting in their turbo compressor casing. The 6. seven Cummins is the workhorse, without doubt about it, but the way it handles crankcase pressure from the factory results in a lot to be desired.
For individuals who aren't familiar along with the technical headache, the stock setup uses a closed crankcase ventilation (CCV) system. Basically, as the engine runs, stress builds up in the crankcase. That pressure contains oil mist and blow-by gases. Instead of simply venting that stuff into the surroundings like the aged 5. 9 Cummins used to do, the 6. 7 routes this back into the consumption. The idea is to burn those vapors off for exhausts reasons, but within practice, it simply ends up coating your turbo, intercooler, and boots in a thick layer of oily grime.
Why People Create the Switch
The main cause most guys appear into a crankcase filter delete 6. 7 Cummins is to prevent the "oiling" of the intake system. When you accomplish your intake car horn or look in the cold-side intercooler boots on a high-mileage truck, they're usually soaked. This essential oil doesn't just sit there; it degrades the rubber boot styles over time, making them soft and prone to blowing off below boost. It furthermore coats the intercooler fins, which may actually hurt your cooling efficiency over the long carry.
Then there's the filter alone. That big rectangular box sitting on top of your own valve cover isn't cheap. Depending upon where you buy it, you're taking a look at a chunk associated with change every 67, 500 miles—or sooner if your vehicle sees a great deal of idle time. By deleting the filter, you're basically removing a servicing item and the potential point of failure. If that filter gets completely clogged and a person ignore the warning lights, the stress has to move somewhere. Usually, that will "somewhere" is by means of your rear major seal or additional gaskets, that is a significantly more expensive fix than a basic delete kit.
How the Delete In fact Works
Whenever you decide in order to go through having a crankcase filter delete six. 7 Cummins , you're essentially transforming the system from a "closed" cycle to an "open" loop. Most sets come with a few basic components: a block-off plate for the consumption connection and a new breather set up for your valve cover.
You'll remove that bulky factory filter element and replace it along with a plate or even a specialized cap. Instead of the blow-by gases getting sucked back in the particular turbo, they get routed through a hose. Most people run this hose pipe down the aspect of the motor and vent this toward the terrain, much like the "puke tubes" upon the older 12-valve and 24-valve engines.
It's a simple mechanical fix. No even more oil in the particular turbo, no more expensive filters to purchase, plus the engine gets to breathe a lot easier. You might discover a slight "diesel smell" standing near the truck at a red light, but for most Cummins owners, that's simply the smell of the healthy engine.
The Messy Truth of the Share Filter
If you've ever used apart a six. 7 Cummins along with 100k miles on it that still has the stock CCV setup, you understand how nasty it gets. The oil mist mixes using the soot coming from the EGR valve (if that's nevertheless intact) and creates a thick, dark sludge. This sludge builds up upon the grid heating unit and the consumption valves.
By performing a crankcase filter delete six. 7 Cummins , you're cutting away half of that equation. Even in the event that you're running a completely stock emissions set up otherwise, keeping that will oil from the consumption is a huge win for the particular longevity of the particular engine. It retains the MAP sensor cleaner, meaning the ECM gets better readings as well as the pickup truck runs smoother. It's a small transformation that has the huge "trickle-down" impact on the rest of the engine's health.
Installation Tips and Techniques
Installing the delete kit isn't exactly rocket science, but there are a few issues to keep in mind so that you don't end up with chaos on your own driveway. First off, create sure your in-take hose is sent correctly. You need it to have a great, downward slope with no "dips" or "traps. " If essential oil collects in a low spot in the hose, it can freeze during winter or just block the airflow, which usually increases pressure back again in the engine.
Another issue to consider is the hose length. You want it lengthy enough to vent beneath the vehicle so the oily mist doesn't coat your front axle or suspension elements, but not therefore long it gets caught in the drive shaft or melted upon the exhaust. Zip ties are your very best friend here. Protected that line well, and you'll never have to think regarding it again.
Dealing with the particular Dash Lights
Now, here is definitely where it gets just a little tricky for some folks. The particular truck's computer expects to see that filter there. With respect to the year of your own truck and the specific kit you buy, you might get a "Service Perform" light or a "Crankcase Filter Full" message even with you've installed the delete.
Most high-quality crankcase filter delete 6. 7 Cummins kits include a method to trick the messfühler or a plug that handles the particular electronics. If you're managing a tuner, a person can often just clear the maintenance reminder or change off the monitoring for that particular sensor. If you're carrying this out on a totally stock truck without a tuner, just be ready to do a manual reset of the assistance light (the outdated "brake and gasoline pedal" dance) to keep the dents at bay.
Could it be Worth This?
From a pure mechanical standpoint, the particular answer is nearly always yes. Any time you can prevent dirty, warm oil from entering your turbocharger, you're doing the machine a favor. Turbos are precision devices that spin with incredibly high RPMs; they don't exactly love being coated in crankcase gunk.
The particular only real downside is the environmental aspect—which is why these sets in many cases are labeled with regard to "off-road use only"—and the casual drip of oil on your driveway if the engine has a lots of blow-by. But honestly, in comparison to the cost of a taken turbo or even a seeping rear main seal because of a clogged filter, the little drip of oil is a little price to pay.
Final Thoughts
At the end of the time, a crankcase filter delete 6. 7 Cummins will be one of individuals "set it plus forget it" mods. It simplifies the particular engine bay, will save you money upon filters every year, plus keeps your intake tract resembling it did the day this rolled off the set up line.
If you're someone who plans on keeping your Joker Ram for the particular long haul, taking care of the particular CCV system is usually just part associated with the deal. Whether you go along with a basic vent-to-atmosphere kit or an even more complex catch may setup, getting rid of that stock filter is a solid move for anyone which actually uses their own truck for actual work. Just get a basic tool set, a Sunday morning, and you can get this task knocked out just before lunch. Your turbocharged will definitely thanks to it.
