Perfect Fit
Great grommets to use in your valve covers for the valve stems. Great value and functionality. I recommend paying attention though. These are two different sizes on the inside diameter. They both fit into the valve covers but are meant for two DIFFERENT size valve stems. That is something that I did not realize when I ordered them. It wasn't until I placed the second grommet into my second valve cover - Spectre brand valve covers (which look GREAT) - I ended up having to get a second pack from a local parts store to finish replacing my valve covers. Again, great grommets and highly recommend them for sure. Grommets and valve cover installed in a 1994 Chevrolet Silverado K1500

Perfect little grommet for the CCV Diesel engine issue
Used this set in conjunction with "MotoRad MO-75 Crankcase Breather Oil Cap”, for my 2001 Diesel engine. To resolve the CCV topic - issue diesels are known for. Used the breather cap and this grommet to seal it. Put it in the Right side Valve cover. Left side VC, I just removed the little 90 degree hose piece and plugged in More hose. (was very snug fit yet I Prevailed and accomplished it). The whole Idea was from Clint of “Custom Works” YT community. Removed it and punched the hole in it, ran the emission grade hose down by the frame.

Used on gen I SBC
Fit great on some valve covers for a gen I SBC. Light lubing of motor oil and they pop right in. Nice tight seal for the PCV as well. Highly recommend over parts store if you can wait a day or two.

The replacement part is a perfect fit
I had to reorder from 3 suppliers before I got the proper size grommet that the sellers advertised.
