Honda 11856-RCA-A00 PCV Tube

First of all, given that under-hood temperatures are high, it is vital to regularly inspect engine, accessory, and emission system hoses. Look for cracks, loose clamps, hardening or leaks. The PCV system hose should be checked for cracks and obstructions while vacuum hoses should be thoroughly examined. A small vacuum hose should be used to detect leaks. When disconnecting fuel lines, avoid fuel spillage and check them for deterioration and cracks. Replace fuel hoses with specific ones for your system and use screw clamps if needed. Check metal lines for bends or cracks, using seamless steel tubing for replacements.

Always make sure you check the hoses of your car regularly, as they may wear away because of the heat that is in the hood. You should be observant on cracks, loose clamps, hardening, and leakage, and that clamped hoses stay tight. If there are any cracks or blockages in the PCV system hoses inspect them, but proceed to checking if vacuum hoses can actually fit into materials. You can use a small vacuum hose to detect leaks. Before taking out fuel lines, reduce the pressure of the system and search for signs of decay or broken parts. Fuel lines have to be attached using screw clamps designed for your system as well as replace any corroded complex parts. Alternatively, if necessary always examine brake systems thoroughly by first performing a check if metal brake lines are cracked or leaking.

The rubber and plastic hoses should be inspected regularly.

The PCV valve regulates the flow of crankcase vapors into the intake manifold, maintaining idle quality by restricting flow when intake manifold vacuum is high and allowing full flow when vacuum decreases.
