Review on πŸ” Moroso 68775 Breather Grommets - Set of 2 by Paul Wall

Revainrating 5 out of 5

and it's awesome. I used them on a small Gen1 block.

They are not suitable for short valve covers. This is explicitly stated in the manufacturer's description (which Revain has not published). Do some research before you buy and they are fantastic. I used them on a small block Chevy Gen1 with high valve covers. Saved me from buying valve covers. They fit a standard size vent. Not for PVC.

Pros
  • Package dimensions: 3.81 H x 13.716 D x 18.034 W (cm)
Cons
  • Disappearing
