The 6.2L V8 in your Silverado (the L86, L87, or L8T family) makes serious power, but its direct-injection design has one well-known weakness. Because fuel sprays straight into the cylinder instead of washing over the back of the intake valves, oil vapor pulled through the PCV system bakes onto those valves and forms carbon deposits over time. A quality oil catch can intercepts that oily blowby before it ever reaches the intake, and on these trucks it is one of the smartest preventative upgrades you can bolt on.
We looked at the catch cans that actually fit the 6.2 Silverado without hacking up your engine bay, focusing on direct-bolt brackets, proper internal baffling, and clean PCV routing. Below are our top seven picks, ranked, so you can pick the right can whether you tow heavy, run a tune, or just want your L87 to stay healthy past 150,000 miles.

1. JLT 3.0 Oil Separator (Driver Side, GM Truck 6.2L): Best Overall
JLT has been building oil separators for GM trucks longer than almost anyone, and the 3.0 is the can we kept coming back to for the 6.2 Silverado. It is not a hollow tube with a fitting on each end. Inside it uses bronze filter media that forces the crankcase vapor to give up its oil before the clean air continues to the intake, and on a direct-injection L87 that is exactly the behavior you want. The vehicle-specific bracket bolts to existing points so the install is genuinely a driver-friendly job with hand tools, and the result looks like it came from the factory.
The honest weakness is that it works almost too well. Because the JLT actually captures fine mist rather than letting it slip through, the can fills faster than budget units, so you will be emptying it on a real schedule rather than forgetting about it for a year. It is also a single driver-side separator, so if you want to address both PCV ports on the engine you are looking at a second can. For most owners running one well-placed JLT, the carbon protection and build quality make it the can to beat.
- CNC-machined billet aluminum body that mounts on a vehicle-specific bracket for the 6.2 truck
- Internal bronze filter and coalescing media that trap fine oil mist instead of just slowing airflow
- Clear sight window so you can check the collected oil level without opening the can
Pros: Genuinely effective at separating oil mist on direct-injection GM V8s; Bolt-on bracket means no drilling and a factory-clean look; Easy to empty and the media is serviceable rather than throwaway
Cons: You should empty it more often than cheaper cans because it catches so much; A single driver-side unit only addresses one PCV path on the engine
2. Mishimoto Baffled Oil Catch Can, 2-Port: Best Baffled Design
Mishimoto’s baffled can is the engineering enthusiast’s pick. Where many universal cans are just a chamber with two fittings, this one runs the vapor through a 50 percent baffle, then bronze filter media, then an air diverter, so the oil has three chances to drop out before clean air reaches your intake manifold. On a 6.2 Silverado that is doing real work, towing or running a tune, that staged separation noticeably reduces the oil film you would otherwise find building in the intake tract.
The trade-off is that it is a universal can, not a bolt-in kit specific to the truck. You will need to source or fabricate a bracket and trim the PCV hose to length, which makes the install a step harder than a vehicle-specific JLT. It also has a slightly larger body, so plan your mounting location before you order. If you do not mind the extra setup, the quality of the separation and the threaded drain make this one of the best cans you can run on the platform.
- Three-stage internal separation with a baffle, bronze filter, and air diverter
- Billet aluminum body with a threaded bottom for fast, clean draining
- Includes mounting hardware and fittings to integrate into the 6.2 PCV line
Pros: Excellent internal engineering that separates oil better than most universal cans; Backed by a strong warranty and quality fittings; Threaded drain plug makes emptying tidy and quick
Cons: Universal fit means you supply your own bracket and routing for the Silverado; Slightly larger footprint can be tight in a crowded engine bay
3. RX Oil Catch Can Kit for GM 6.2L (Direct Fit): Best Direct-Fit Kit
If your priority is a no-fuss install, the RX direct-fit kit is built around the 6.2 GM truck specifically, so the bracket lines up, the hoses are pre-bent, and the whole thing follows the factory PCV routing instead of a tangle of universal hose. For an owner who wants catch-can protection without studying diagrams, this is among the most approachable kits for the Silverado. Inside, dual baffle plates give the vapor room to slow down and shed oil before it heads back toward the intake.
The honest limitation is that it leans on baffling rather than dense filter media, so under extreme blowby it will not separate quite as much fine mist as a bronze-filter can like the JLT or Mishimoto. For a daily-driven or lightly worked 6.2 that is more than enough, and the complete, truck-specific package makes the install genuinely satisfying. Just check the can occasionally in the first month to confirm your routing is capturing oil as expected.
- Designed specifically for the GM 6.2 truck engine with a model-matched bracket
- Pre-formed hoses and fittings so the routing follows the factory PCV path
- Dual internal baffle plates to slow and separate the crankcase vapor
Pros: True bolt-on kit with everything in the box, minimal guesswork; Clean factory-style routing keeps the engine bay tidy; Good value for a complete vehicle-specific package
Cons: Baffle-only separation is a touch less aggressive than filter-media cans; Anodizing color options are limited
4. UPR Products Plug and Play Oil Catch Can (GM Truck 6.2): Best Plug-and-Play
UPR’s plug-and-play can is built for the owner who wants to keep the factory PCV connections intact. Instead of cutting hose, it uses OEM-style quick-connect fittings that snap into the 6.2 Silverado’s existing lines, so a careful first-timer can have it mounted in well under an hour. The twist-off bottom cup is the standout feature day to day, because emptying the collected oil takes no tools and no mess, which means you are far more likely to actually maintain it.
The thing to watch is the quick connects. They make the install fast, but if a fitting is not fully seated you can introduce a small vacuum leak that throws a code, so take your time and listen for the click. The base configuration relies more on internal baffling than dense media, though UPR offers filter upgrades. For convenience and build quality on the platform, this is a strong, friendly choice that respects the factory system.
- OEM-style quick-connect fittings that snap into the factory PCV line
- Twist-off bottom cup for tool-free emptying
- Billet aluminum can and bracket made in the USA
Pros: Quick-connect fittings make the install one of the fastest available; Twist-off cup is genuinely convenient to drain; Solid billet build and USA manufacturing
Cons: Quick connects must seat fully or you can get a small vacuum leak; Bronze filter is optional, base model relies more on baffling
5. Elite Engineering E2X Catch Can with Clean Side Separator: Best Dual-Side Coverage
Elite Engineering takes the most complete approach on this list by pairing a dirty-side E2X catch can with a clean-side separator. On the 6.2, oil vapor can travel through more than one crankcase path, and addressing only the dirty side leaves a gap. By covering both, this system catches oil that single-can setups miss, and the fine micro-mesh media inside is genuinely good at pulling down the fine mist that slips through coarser baffles. For an owner who wants maximum intake protection, this is the thorough option.
The cost of that thoroughness is complexity. You are installing two devices, finding mounting room for both, and routing more hose, so it is the most involved job here and better suited to someone comfortable spending an afternoon under the hood. If you only want a quick bolt-on, this is more than you need. But if you are serious about keeping a high-mileage or tuned 6.2 as clean as possible, the dual-side coverage earns its place.
- Pairs a dirty-side catch can with a clean-side separator to cover both PCV paths
- Fine micro-mesh internal media targets very fine oil mist
- Integrated drain hose lets you empty without removing the can
Pros: Addresses both crankcase ventilation sides for fuller protection; Micro-mesh media is very effective on fine vapor; Drain hose makes maintenance simple
Cons: Two-piece system costs more effort to install; More components to find room for in the engine bay
6. Mishimoto Universal Compact Baffled Oil Catch Can: Best Compact Fit
Not every 6.2 Silverado has obvious open real estate near the PCV port, especially if you have already added other accessories. The compact Mishimoto solves that by shrinking the body while keeping a real internal baffle and bronze filter inside, so you are not trading away separation just to fit. For a tight engine bay this is often the can that actually mounts where you want it, and the threaded drain bolt keeps emptying clean.
The obvious trade-off is capacity. A smaller can holds less oil, so on a high-blowby 6.2 you will be draining it more often to keep it from filling and reducing effectiveness. It is also universal, meaning you supply the bracket and cut the hose to length. If you have the space for a full-size can, choose that instead. But when clearance is the deciding factor, this compact unit punches above its size and keeps the protection where it counts.
- Smaller billet body that fits tight spots in the Silverado engine bay
- Internal baffle plus bronze filter despite the compact size
- Threaded drain bolt on the base for clean emptying
Pros: Fits where full-size cans will not; Retains real filter media in a small package; Easy to drain and good build quality
Cons: Smaller reservoir fills sooner and needs more frequent emptying; Universal fit requires your own bracket and routing
7. EVIL ENERGY Baffled Universal Aluminum Oil Catch Can: Best Value Pick
EVIL ENERGY’s baffled can is the accessible entry point for a 6.2 Silverado owner who wants real catch-can function without a premium-brand commitment. It is more than a hollow chamber, with internal steel filter media and a proper baffle, plus a base drain valve that makes routine emptying genuinely easy. It ships with a bracket and fittings, so you have what you need to adapt it to the truck’s PCV line and start protecting your intake right away.
Where it shows its position is in the small details. The fittings and seals are not machined to the same tolerance as the JLT or Mishimoto, so you will want to double-check every connection for leaks and possibly upgrade a hose clamp or two. The separation is good but not class-leading under heavy blowby. For a daily-driven 6.2 where the owner wants solid protection and easy maintenance, this can delivers a lot of capability and is the value standout of the group.
- Baffled aluminum chamber with internal steel filter media for the price point
- Built-in drain valve at the base for fast, mess-free emptying
- Includes mounting bracket and fittings to adapt to the 6.2 PCV line
Pros: Strong qualitative value with features usually found on pricier cans; Drain valve is a genuinely handy maintenance feature; Comes with bracket and hardware to get started
Cons: Fittings and seals are not as refined as premium brands; Universal design means careful routing and leak checks are on you
Frequently Asked Questions
Does a catch can really help the 6.2 Silverado?
Yes, and it matters more on this engine than on most. The 6.2 V8 uses direct injection, which means fuel never washes over the back of the intake valves the way it did on older port-injection engines. That leaves oil vapor from the PCV system free to bake onto the valves and form carbon over time. A catch can intercepts that oily vapor before it reaches the intake, so it directly targets the 6.2’s biggest long-term weakness. It will not undo existing buildup, but installed early it meaningfully slows carbon accumulation and keeps the intake tract cleaner for the life of the truck.
Which side of the 6.2 should I install the catch can on?
The most common and most effective single-can placement is on the dirty side, which is the PCV line carrying oil-laden vapor from the crankcase to the intake under vacuum. That is the path that deposits oil on your valves, so catching it there gives you the most protection per can. Many owners stop there and are very happy. If you want fuller coverage, a dual setup also adds a clean-side separator on the fresh-air line, which catches oil that travels the other direction under boost or heavy load. For most 6.2 Silverados, start with a quality dirty-side can and add the clean side later if you want maximum protection.
How often do I need to empty the catch can on a 6.2?
It depends on how the truck is driven and how effective the can is, but a good rule is to check it every oil change at minimum, which is roughly every 5,000 to 7,500 miles. A high-quality can with real filter media on a truck that tows or runs a tune can collect a surprising amount of oil and may need attention sooner. When you first install a can, check it after the first few hundred miles to learn your truck’s rate, then settle into a schedule. Cans with a drain valve, twist-off cup, or sight window make this far less of a chore, which is why those features are worth prioritizing.
Will adding a catch can void my Silverado warranty?
Under the Magnuson-Moss Warranty Act, a manufacturer generally cannot void your entire warranty simply because you installed an aftermarket part. They can deny a claim only if they can show the part actually caused the specific failure. A properly installed catch can that does not introduce a vacuum leak is very unlikely to cause an engine problem, so the practical risk is low. That said, install it correctly, keep your factory PCV components intact where possible, and choose a can that uses OEM-style or properly sealed fittings. If you are concerned, a plug-and-play kit that does not permanently alter the factory lines is the safest path.
Can I install a 6.2 Silverado catch can myself?
Absolutely, this is one of the more beginner-friendly bolt-on jobs on the truck. A vehicle-specific or plug-and-play kit, like the JLT, RX, or UPR options, comes with a matched bracket and pre-fit hoses, so the work is mostly mounting the bracket, connecting the PCV line through the can, and double-checking your fittings. Basic hand tools and an hour are usually enough. Universal cans take a bit more effort because you supply the bracket and cut hose to length. Whichever you choose, the most important step is confirming there are no vacuum leaks afterward, since a loose fitting is the main thing that can trip a check-engine light.
Our Verdict
For most 6.2 Silverado owners, the JLT 3.0 Oil Separator is the catch can to buy. Its bronze filter media genuinely separates oil mist on direct-injection GM V8s, the vehicle-specific bracket makes for a clean bolt-on install, and the build quality is hard to fault, which is why it takes our top spot. If you want the most refined internal engineering and do not mind sourcing your own bracket, the Mishimoto Baffled 2-Port is an outstanding runner up with three-stage separation and a tidy threaded drain. Either way, fitting a quality can early is one of the best preventative things you can do for the long-term health of your 6.2.
