Overview
The Crown Automotive 53000957 is a PCV valve grommet with a .66 to .72 in inner diameter. A PCV grommet sits in the valve cover opening where the positive crankcase ventilation valve is seated.
Crown Automotive offers it among its replacement parts for Jeep vehicles. Measure the opening in your valve cover so the .66 to .72 in range matches before fitting it.

Measuring the PCV opening
A PCV grommet holds the positive crankcase ventilation valve in the valve cover, letting crankcase vapors pass to the intake while keeping the cover sealed. Because the valve is a snug press or friction fit, the opening size matters. An opening that is too large can let the valve shift and leak, and one that is too small can make the valve hard to seat.
Before buying, measure the existing opening and the valve body with a caliper. Compare those figures with the diameter range given for this grommet. If the valve or the opening has been worn or enlarged, replacing the grommet alone may not restore the seal, so inspect the valve cover in the same job.
- Check the PCV valve for cracks or a sticking plunger
- Look for oil around the valve cover opening
- Replace the valve and grommet together when either is worn
