Engine Crankcase Breather Hose Kit (Silver lids)

The engine crankcase breather hose is a key part of your vehicle’s positive crankcase ventilation (PCV) system. Its main role is to route pressurized gases from the engine crankcase to the PCV valve (also called the air/oil separator). The PCV valve captures harmful oil  vapers , drains them back into the engine, and redirects the cleaned air to the intake system to be burned during normal combustion.

Without a properly functioning breather hose, your engine can develop performance issues, oil leaks, and even emissions failures.

Why the Engine Crankcase Breather Hose Matters

During combustion, engines naturally produce positive crankcase pressure. This pressure combines with heat and oil vapers inside the crankcase. The breather hose is designed to handle this flow and keep your PCV system working efficiently.

Over time, however, exposure to heat, oil, and pressure makes the breather hose a common failure point. When damaged, it can cause poor performance, check engine lights, and increased emissions.

Common Symptoms of a Failing Crankcase Breather Hose

• Cracks, leaks, or breaks – Heat and oil vapers degrade rubber or plastic over time, leading to air leaks.
• Broken connectors or clips – Brittle plastic can snap during service or due to age.
• Visible damage – Hoses may split, soften, or harden, creating noticeable holes.
• Check Engine Light (CEL) – Unmetered air from a leak often triggers intake-related fault codes.
• Engine misfires or rough idle – Severe air leaks upset the air/fuel mixture, causing misfires.

Oil residue or odour – Escaping vapers leave oily deposits on the hose, engine block, and nearby components. In severe cases, you may smell burning oil.

Why You Shouldn’t Ignore a Bad Breather Hose

A faulty crankcase breather hose affects engine performance, fuel efficiency, and emissions compliance. Left untreated, it can cause long-term engine damage and costly repairs.

If you notice any of the above signs, it’s important to inspect and replace your crankcase breather hose as part of regular PCV system maintenance.

What is an Engine Timing Chain?

The timing chain is a vital component in an internal combustion engine, responsible for synchronizing the rotation of the crankshaft and camshafts. This precise coordination ensures that engine valves open and close at the correct times during each cylinder’s intake and exhaust strokes, allowing for smooth performance and efficiency.

While designed to last the lifetime of the engine, timing chains can wear, stretch, or become damaged. A worn chain can alter engine timing, strain the tensioners, and, if left unaddressed, lead to catastrophic engine damage and costly repairs. 

Signs of Timing Chain Kit Failure

Noise: A failing timing chain often produces a rattling or slapping noise, particularly noticeable at startup, idle, or during acceleration.

Reduced Performance: Stretched or worn chains can disrupt engine timing, resulting in sluggish acceleration, reduced power, or poor overall performance.

Engine crankcase vent breather valve Kit

Crankcase Breather Kit Overview The crankcase breather kit includes the breather valves (also called the air/oil separator or PCV valve) and the breather hoses. These components are typically made of plastic, making them prone to cracking or failure over time. Replacing or maintaining this system proactively improves engine reliability and ensures optimal performance.

Signs of a failing crankcase breather system include air or oil leaks, fouled spark plugs, or blue smoke from the exhaust. If you notice any of these symptoms, inspect the breather system and replace components as needed.

Engine Crankcase Breather Hose Kit

The crankcase breather hose is a key part of the engine’s positive crankcase ventilation (PCV) system. It channels pressurized air from the engine crankcase to the PCV valve (air/oil separator). The PCV valve captures and removes oil vapors, draining them back into the engine while sending the remaining pressurized air to the intake for combustion.

Positive crankcase pressure naturally develops during engine operation. Because the hose is constantly exposed to heat, pressure, and oil vapors, it is one of the most common failure points in the PCV system. A damaged or worn hose can impact engine performance, emissions compliance, and overall reliability.

Common Crankcase Breather Hose Failure Symptoms

Cracks, breaks, or leaks: Constant exposure to heat, pressure, and oil vapors can degrade the plastic or rubber, causing air leaks. External damage can also contribute.

Broken connectors or clips: Plastic connectors and securing clips may become brittle over time, breaking during removal or routine maintenance.

Holes or splits in the hose: Soft rubber or brittle plastic can develop visible splits or holes, often accompanied by other issues listed below.

Check Engine Light (CEL): Excess unmetered air from a failed hose can trigger an air intake leak fault or related diagnostic codes.

Engine misfire: Severe air leaks can cause rough running or misfires, a common side effect of a faulty hose or PCV valve.

Oil residue: Escaping vapors often leave visible oil on the hose, engine block, or surrounding components. In severe cases, burnt oil may be noticeable, and the area may require degreasing to locate the source.

Maintaining a healthy crankcase breather system is essential for engine longevity, smooth operation, and proper emissions control.
