🖥️ Enhanced Performance PCV Valve Grommet by Standard Motor Products GV29 Review

That was the most interesting tuning of my car. It is not cracked, round and plastic! I couldn't wait to install it and when I did; it worked!

Came in an intermotor box and looked exactly like the old one that came out (but in pieces). Use some oil inside and outside to make the installation smoother. Installed on Miata 1991.

I am baffled by claims that this item will fit Miata 1.6 NA. I've even seen a claim that it fits another 1991 like mine. The product may have changed or there were several versions. I don't know but I've tried 2 of these and I'm telling you they don't fit. You can EITHER insert the sleeve into the hole in the valve cover OR you can insert the PCV valve into the sleeve (as long as it is outside the hole). But if you try to do both at the same time, the sleeve will break. It doesn't matter how…
