VG612600010267 Howo O2 Engine Oil-Gas Separator

The VG612600010267 oil-gas separator is made strictly for Howo O2-series engines-don't try slapping it on an O3/O4 engine or a non-Howo truck, it won't fit right. It's a key part of the engine's crankcase ventilation system, and its only job is to split oil mist from the blow-by gas the engine makes when it runs.

I've seen too many engines suffer 'cause of bad separators: oil gets sucked into the intake, burns up, and leaves carbon buildup on injectors. This one? It uses a two-step setup-first a cyclonic spin to throw big oil droplets out, then a glass fiber filter to catch tiny ones (down to 5μm). That means almost no oil gets through to the intake.

The main body's heavy-duty aluminum alloy, not cheap plastic. Last summer, I worked on a Howo truck that sat in the sun all day-engine bay hit 115°C, and this separator didn't warp or leak. The inlet and outlet are drilled exactly to match the O2 engine's ventilation hoses, so you can yank the old one off and bolt this on without cutting or stretching hoses. It also has an oil return valve that sends collected oil back to the pan automatically-no need to take it apart to drain oil like those cheap aftermarket ones.

Applicable Model: Howo O2-series diesel engines. If you're not sure, check your engine serial number (it's stamped on the block) or call a Howo parts shop-they'll confirm in 20 seconds.

Part Function: Separates oil mist from crankcase blow-by gas; keeps oil out of the intake and maintains emission compliance.

Structural Design: Two-stage separation (cyclonic + glass fiber filter); with automatic oil return valve.

Material: Main body: Heat-resistant aluminum alloy; Filter: Glass fiber composite.

Working Temperature Range: -40°C to +120°C. Works in freezing northern winters and scorching southern summers-no issues.

Oil Separation Efficiency: ≥98% for oil droplets 5μm and bigger. Maximum Working Pressure: 0.3 MPa.

Inlet/Outlet Diameter: 32mm-exact match for Howo O2 engine ventilation pipes.

Weight: About 1.8 kg. Heavy enough to feel solid, not so heavy it's a hassle to install.

Mounting Type: Bolt-on. Uses the engine's original brackets-4 holes, lines up perfect.

Certifications: Meets Howo's OEM standards, plus GB/T 19001-2016. Passes O2 emission tests, no problem.

Cleans oil mist like a pro: That two-stage setup catches almost all oil. A long-haul driver told me he used to top up oil every 5,000 km-after swapping to this, he goes 8,000 km. It also stops carbon buildup on injectors, so engine overhaul intervals stretch by 30%. Tough as nails, no leaks: Aluminum alloy body doesn't melt or crack like plastic separators. I've seen cheap ones leak oil all over the engine bay-this one's sealed tight. The valves and interfaces fit perfect, so no oil drips or unfiltered gas escaping. No extra maintenance: The automatic oil return valve does the work-no need to take it apart to drain oil every few months. Unlike old separators that need cleaning every 10,000 km, this one just runs until it's time to replace. Installs fast, no fuss: It's a direct OEM fit. I installed one last week in 25 minutes-just unbolt the old one, line up the hoses, and tighten the bolts. No cutting hoses or drilling new holes, even a new mechanic can do it. Saves oil and keeps emissions in check: Less oil burned means you buy oil less often-saves money. It also makes sure the engine meets O2 emission rules, so you don't fail inspections or get fined.

This separator's only for Howo O2-series engines-here's where you'll see it:

Howo heavy-duty trucks: A7, T7H models with O2 engines-guys hauling freight cross-country use these most. Howo construction gear: Excavators, loaders with O2 engines-they run hard, so they need a tough separator. Howo special vehicles: Tanker trucks, cargo vans with O2 powertrains-any O2 engine Howo makes, this fits. Use it when: Replacing old parts: If your old separator leaks, clogs, or makes the engine burn too much oil-swap it. Don't wait 'til the engine gets damaged. Routine maintenance: When you do a 20,000–30,000 km service, throw a new one on. Old separators look okay but lose efficiency over time. Passing emissions tests: If your truck's failing O2 checks, a bad separator is often the culprit-this one fixes that. Fleet upkeep: Logistics or construction companies with Howo O2 trucks love these-standardizing on OEM parts means fewer breakdowns. Heads up: Don't use it on O3/O4 engines or non-Howo trucks (like Shacman, FAW). The hoses and mounting won't line up, and you'll mess up the engine. Always check the engine model first.

Q1: Will this fit my 2018 Howo T7H with an O2 engine?

A1: Yep, 2018 T7H O2 models are exactly what this is for. To be sure, give the parts shop your engine serial number-they'll confirm it's a match.

Q2: How do I know my separator's bad?

A2: Look for these signs-hard to miss: Engine burns oil fast-you're topping up every few thousand km. Blue or white smoke from the exhaust-means oil's getting burned. Oil stains around the separator or hoses-leaks are a dead giveaway. Engine power drops or fuel use goes up-carbon buildup from oil can cause this. Replace it fast-waiting will damage the engine.

Q3: Can I clean the filter instead of replacing the whole thing? A3: No, don't try. The filter's glass fiber-washing it or blowing it out with air ruins the layers. Once it's clogged, it can't separate oil anymore. Just replace the whole separator when it's time (usually 60,000–80,000 km).

Q4: Why not buy a cheap aftermarket separator?

A4: They're not worth it. I've seen them leak after a month, or only separate 70% of the oil. That means more oil burned, more engine wear, and failed emissions. You'll end up buying a new one anyway, plus fixing engine damage-costs more in the long run.

Q5: What maintenance does it need after installing?

A5: Barely any. Every 30,000 km, check the hoses for cracks and make sure the oil return valve isn't blocked (use compressed air to clear it if it is). That's it-no other work 'til it's time to replace.
