Crankcase Vent Tubes

A crankcase ventilation tube efficiently removes of blow-by gases through the intake manifold while keeping pressure at a safe level. A functional crankcase vent tube helps to prevent oil leaks and build-up while working with additives in oil to limit the amount of moisture. The condition of a crankcase breather tube can indicate whether any of these factors may pose a threat to your engine. In addition to installing a functional vent tube, regular oil changes can prevent engine damage. Browse or search for Jeep crankcase parts from manufacturers including Crown Automotive, Dorman, Omix-Ada and Jeep on 4 Wheel Parts.

Compare Designs
4 Wheel Parts stocks several different designs of crankcase vent tubes from different manufacturers. Make sure that any tube you are considering is compatible with your engine size and the number of cylinders. Most tubes install in the rear of the valve cover. You may also want to look for measurements of the outside and inlet diameters. Installing most crankcase tubes, including a Jeep 4.0 crankcase breather, is often as easy as pressing into place. Look for tubes that are resistant to brittleness, cracking and exposure to oil.

    Whether driving down the highway or through the Rockies, your Jeep should never be burning oil or leaking oil for that matter. Both are signals that there is a problem with your crankcase. It could be as simple as the Jeep 4.0 valve cover breather has gone bad or that a valve needs to be replaced. 4 Wheel Parts has everything you need to get back out there. Simply select your make and model from the drop-down menu and select the parts you need. We have everything right at your fingertips.

    Signs of a Bad PCV Valve
    If you've been replacing your oil more frequently than just your scheduled oil change, you could have a leak in your PCV valve. Without the pressure release, the oil goes around gaskets and seals causing your engine to leak or burn oil.  The crankcase breather filter becomes contaminated when the PCV valve needs to be replaced. If the filter gets clogged with contaminants, the added pressure makes your Jeep burn through fuel faster. You will need to replace both the breather and the valve if the filter is clogged. Or maybe you're just noticing overall negative performance in your engine. All could be signs that you need to replace your breather, vent tubes and/or valve. Doing so before your engine is completely clogged saves you time and money down the road.
