Since I had recently acquired a nice set of valve covers, I found the cap/PCV valve setup that I needed to complete the job.

These look sharp on my tall smooth aluminum valve covers. Looks very well made with tight tolerances. Helps complete the race look! Well worth the money.

Good value, good quality, good price.

My aftermarket cast aluminum valve covers each have a "twist in" hole for a filler cap/breather. I had no pcv. I wanted a replacement for an existing cap that included a pcv. This product came with a large rubber grommet that fits the existing opening and provides the needed pcv function. It is also a nicely machined aluminum housing with a 3/8" hose connection as needed.

I would purchase this item again

This is much nicer and better looking than just a pcv sticking out of the valve cover ! I got the matching breather for the other side and they look great.

This piece is one of those details that many overlook. Nothing worse than a nice, chromed out motor with a nasty old plastic pcv valve jammed in your valve cover. This ends that problem!

Do I have to drill holes in the grommet? My grommets fit but they are actually plugs without an opening.
