Breather hose from front of block to valve cover
$39.99
The 037103211A Breather Hose connects the engine block to the valve cover, ensuring proper crankcase ventilation and pressure balance. This hose is a critical part of the PCV (Positive Crankcase Ventilation) system, designed to route blow‑by gases back into the intake system to reduce emissions and keep the engine running smoothly.
With time, factory breather hoses can become brittle, crack, or collapse due to heat and oil vapor exposure, leading to oil leaks, vacuum leaks, rough idle, or check engine lights. Replacing the breather hose with this OEM‑quality part restores factory sealing, efficient emissions control, and smooth operation.
