Oil Catch Can
What is an Oil Catch Can and How Does It Work?
In modern internal combustion engines—especially turbo-diesel trucks, 4WD off-roaders, and high-performance vehicles—combustion gases can escape past the piston rings and into the crankcase, a process known as blow-by. These gases often contain oil mist, unburned fuel vapors, and moisture, which are rerouted through the PCV system back into the intake. This can lead to carbon buildup, EGR system contamination, and even turbocharger wear over time.
The SPELAB oil catch can kit addresses this issue directly. Designed for use with both gasoline and diesel engines, it installs between the PCV system and the intake manifold to trap harmful residues before they cycle back into the combustion process. While it doesn’t enhance horsepower or fuel efficiency directly, it offers practical engine protection and lower long-term maintenance, especially for drivers pushing their engines hard.
What Are the Benefits of Installing a SPELAB Oil Catch Can?
Before diving into SPELAB’s oil catch can kit, it's important to understand what this device is and how it works. An oil catch can is a small reservoir installed between your engine’s PCV (Positive Crankcase Ventilation) or CCV (Crankcase Ventilation) system and the intake manifold. Its job is to trap oil mist, fuel vapors, and moisture from blow-by gases before they re-enter the combustion system.
In factory CCV systems—especially on modern turbo-diesel engines like the 2006 Duramax 6.6L, 2017 Ford F-250 6.7L, or 5.7 HEMI—these blow-by gases are often rerouted back into the intake manifold unfiltered. Over time, this causes throttle body sludge, EGR valve contamination, and potential turbocharger damage.
Installing a SPELAB oil catch can kit, particularly when paired with a CCV reroute or delete kit, reroutes and filters these gases to ensure cleaner engine operation and long-term reliability.
Why Choose the SPELAB Oil Catch Can?
Among the many options on the market, the SPELAB oil catch can kit stands out for its premium design and wide compatibility. It features a 300ml high-capacity aluminum tank, a dual-chamber internal baffle system, and a breather filter to improve vapor separation efficiency. With a removable bottom for easy drainage and an integrated dipstick for quick fluid level checks, this catch can is built for convenience and performance.
SPELAB’s universal application allows it to fit both gasoline and diesel vehicles, including platforms like the BMW N54 engine and 2020 RAM 2500 with 6.7L Cummins diesel. It's particularly effective on modified performance engines or heavy-duty applications, such as off-roaders and towing vehicles.
Compared to standard catch cans, the SPELAB oil catch can kit offers superior filtration and user-friendly features, making it a top choice for both DIY enthusiasts and professional tuners looking for reliable engine protection.
Benefits of Installing a SPELAB Oil Catch Can
While the SPELAB oil catch can kit performs well under regular conditions, its real value shines in demanding environments. For vehicles used in heavy towing, off-roading, extended idling, or stop-and-go urban driving—such as the 2021 Ford F-150 EcoBoost 3.5L—engines are more prone to oil vapor buildup, throttle body sludge, and intake carbon deposits. Over time, these can degrade throttle response, turbo efficiency, and fuel-air mixture balance.
Installing a SPELAB oil catch can kit helps separate these contaminants before they enter the intake, preserving throttle performance, reducing carbon buildup, and stabilizing idle RPMs. Many users report smoother throttle response, reduced hesitation, and cleaner intakes after installation.
More importantly, for high-demand driving conditions, the system can save an estimated $300–$600 per year in cleaning and maintenance costs related to the intake system, making it a smart, cost-effective investment for long-term engine care.

Optimized Applications for Specific Diesel Engines
For certain turbo-diesel engines, the factory CCV system routes oily blow-by gases directly back into the intake manifold. Over time, this causes sludge buildup, EGR fouling, intake contamination, and premature turbo wear. The SPELAB oil catch can kit, when paired with a CCV reroute or delete kit, offers tailored protection for these engines:
-
2017 Ford Super Duty F-250 6.7L Power Stroke: Built for towing and heavy loads, this engine benefits from rerouting oily gases away from the intake to protect turbo and EGR systems.
-
2006–2007 Chevy Silverado 2500HD 6.6L Duramax LBZ: Frequently used in off-road and towing scenarios, this engine sees improved intake cleanliness and turbo longevity with a catch can.
-
2022 RAM 1500 3.0L EcoDiesel: Even in light-duty applications, fine oil vapors can accumulate. The catch can reduces oil film in the turbo inlet.
-
2020 Jeep Grand Cherokee 3.0L V6 Diesel: Stop-and-go urban driving leads to PCV inefficiency—installing an oil catch can helps stabilize power delivery and extend maintenance intervals.
SPELAB’s diesel-focused optimization ensures maximum performance, reliability, and protection—without affecting emissions compliance.

Awesome product I put the 3" cutouts on my 78 nova and they work great. Easy to install.
After installing the Spelab intake my EGT’s have lowered about 150/200 degrees from stock! I tow 90% of the time with this truck, I should have done this upgrade way earlier!
This kit came in a very nice box with all the necessary hardware to complete the installation without any modifications. Installation time was about two hours working methodically by myself with some occasional help from my 13 year old son as he passed through the garage. As many others have commented it would be nice to have some printed instructions with the kit, but it is not hard to figure out. I went with the red version because it was the cheapest, and I think it looks great. After installation, custom tuning with a mm3 tuner, and an upgraded exhaust the 6.7 is opened up and free to run.
Great components solid workmanship very happy with the product and looks really rood. I went with the red
I am a mechanic so it’s hard for me to say someone with absolutely no skills that this is easy. But watch YouTube I will say everyone is worried about the egr exhaust bolts. But one video he sprayed them and soak them. I had sprayed mine each time I drove the truck and every morning for 4 days. Than another video a guy said drive the truck get it hot than when you go to take them out hit the socket and extension with hammer to loosen them. So I also did this. They all came out with absolutely no problem. I did have to take off my intake cause I did the ccv and disaster kit as well. And these bolts did not get sprayed. And one did break! I was able to get it out with wd40 and pb blaster and tapping with hammer. To drop dpf I sprayed the hangers with pb blaster used a pry bar and they pop right off. Remember when taking that off you might miss a coupe connectors so take your time! Also the back of dpf I had two broken studs and one so rusted that I had to use a grinder. After got it out I had to take a drill to my existing manifold cause the rusted bolts closed up the holes. Currently I left my dpf tank in the truck. I plan on removing it but I don’t have a reason yes!
Make sure to read all instructions and again take your time. I’m currently having issues updating the mini max cause I didn’t do it before install. But spe hands down was amazing the products everything was perfect besides the intake. The mass air flow sensor didn’t fit and to clean the metal shavings I used brake clean and it melted there spray paint on that one product, everything else i believe is powder coated. I know it’s not part of this kit but the cp4 disaster kit make sure you tighten hose clamps I did not do this and it cam off so I had to take upper and lower intake off on the side of the road and lucky the truck didn’t burn down. But I would say that was my fault for not verifying!
Fits great! Easy install! All parts come with this as well didn’t need to go out and get anything. Not only that but the price man that’s damn good
Good fitment on all items. All block off plates fit good and dont leak. Downpipe fits perfectly. All gaskets included good quality.
I’m so happy with my egr delete kit and intake. I made the best decision in choosing Spelab to enhance my 2500 ram truck. I’ll keep buying more stuff from them. It’s starting to be an addiction!! Thanks Spelab!!
The exhaust and muffler fit great. Had to make one cut but that took no more than a couple minutes to measure and make the cut. I’m very pleased with the muffler included, sounds good but keeps the noise down and no drone in the cab. Will buy again.
Everything fit great. The finish is good and it includes everything you need to get rid of that POs Egr cooler
You know how it goes when you try to save a dollar, you cut cost of quality. But this is actually not the case so far. Finish is smooth, no bad cuts that i could see. Plate wasn’t warped with was a concern for me but no leaks this far. I’d buy again
Love the pipe however one band clamp was damaged upon arrival. I was able to bend it back to the correct form and use it. All hangers were in the correct location took about 30 mins for me to install by myself.
Intake came in nice and shiny looks like a great product also got the red intake plate and man oh man does it look sharp, overall I recommend Spelab products. Looks clean performs even better
Comes quickly in a little box. I work on my truck but am no mechanic. It took me 2 hours to remove and install the kit. Im very happy with the outcome. Im going to give it 5 starts but you do have to reuse the two gaskets on the EGR cooler. My advice is pick them up from the parts store so its all new. Total cost is $24 for both. They should be included but im still very happy.
Great product. Does everything it is supposed to do. I do wish it came with printed instructions. Following along with greasy fingers on my phone was problematic. Also, the hose fitting for the coolant line was a size too small. I had to purchase the correct size.
