Seal the crankcase vent and keep blowby gases in check with the Motorad Engine Crankcase Breather Cap (P/N MO75) — a press-fit metal cap designed to cover the crankcase breather port and prevent oil loss while the engine vents combustion gases. It fits a wide range of classic Chrysler, Dodge, Plymouth, and Jeep models spanning 1971 through 2001, from the Dodge Dart and Plymouth Barracuda to the Dodge Ram 1500 and Jeep Grand Cherokee.
Note: This product is subject to a California Proposition 65 warning for cancer and reproductive harm. See p65warnings.ca.gov for details.
When a crankcase breather cap cracks, loosens, or loses its seal, the signs can include an oily film or residue around the valve cover and breather port, a rough or erratic idle caused by an unmetered air leak into the crankcase, and elevated oil consumption as crankcase pressure pushes oil past seals. If this cap is the source of those symptoms, swapping it with the Motorad MO75 restores the sealed, properly vented crankcase the engine needs.

Is the filter element replaceable, and is hardware included?
No — the filter element is not replaceable; this is a complete replacement cap. It is a press-fit unit, so no additional mounting hardware is required for installation.
Is this a direct-fit replacement for my original breather cap?
Yes. The Motorad MO75 is a standard-replacement, press-fit breather cap built to OE-level tolerances with a 1.00 in (25.40 mm) neck diameter to match the original breather port on the listed applications.
How does a crankcase breather cap work?
It caps the crankcase vent port, allowing controlled venting of blowby gases while its seal prevents oil from escaping. A failed cap can cause oil leaks, oil mist buildup, and rough idle from an unmetered air leak.
