Genuine Nissan RB26DETT Blow-By Gas Breather Hose – R32 R33 R34 GT-R – 11826-05U16
Restore your RB26DETT engine's factory crankcase ventilation system with the Genuine OEM Nissan Blow-By Gas Breather Hose – 11826-05U16, a genuine moulded rubber replacement hose designed for compatible Nissan RB26DETT engines.
This factory breather hose connects the engine's cam covers as part of the original crankcase ventilation system, allowing blow-by gases and oil vapours to move through the intended ventilation passages.
Over time, original RB26 breather hoses can become hard, brittle, swollen or cracked due to prolonged exposure to engine heat, oil vapours and general ageing.
A deteriorated breather hose may allow crankcase vapours to escape, contribute to oil residue around the cam covers or introduce unwanted air into the intake system, depending on the location and operating conditions.
Manufactured to Nissan's original equipment specifications, this genuine replacement hose features the factory moulded shape and connection arrangement for compatible RB26DETT applications.
Whether you're restoring an R32 Skyline GT-R, refreshing an R33 or R34 GT-R engine bay, or rebuilding an RB26DETT, replacing ageing factory rubber components is an excellent way to maintain the original engine configuration.

Why Replace Your RB26 Breather Hose?
The RB26DETT crankcase ventilation system helps manage gases that pass the piston rings during engine operation, commonly referred to as blow-by gases.
The factory breather hoses provide the intended pathways for these gases and associated oil vapours to move through the ventilation system.
After decades of exposure to engine heat and oil vapours, the original rubber hoses may deteriorate and lose flexibility.
Common signs of a worn or damaged breather hose include:
- Cracked or split rubber
- Hardened or brittle hose material
- Oil residue around the cam cover connections
- Loose or deteriorated hose ends
- Visible swelling or deformation
- Crankcase vapour escaping from damaged connections
Replacing a damaged breather hose helps restore the integrity of the original crankcase ventilation plumbing.

For owners maintaining or restoring these vehicles, genuine Nissan engine bay components help preserve the original factory appearance and configuration.

Installation Information
Before installation, confirm that the replacement hose matches the original component and connection arrangement.
Inspect the cam cover breather fittings and any associated clamps for damage, contamination or deterioration.
Remove the original hose carefully to avoid damaging the fittings, particularly if the rubber has become hardened or seized in place.
Install the replacement hose in its intended orientation, ensuring both ends are fully seated and any required retaining clamps are correctly positioned.
Follow the applicable Nissan factory workshop procedure and inspect the connections after installation.
