Overall Assessment

Customers highly commend the product for its quality and practicality. Confirmed qualities include a great fit on valve covers, as stated in multiple reviews. Reviews praise its simple, as advertised features and easy installation process. Material quality stands out, with customers noting its nice chrome finish. One customer even mentioned that its quality matches, if not surpasses, more expensive brands. They also complimented the product's aesthetic, improving the look of their engines. However, some found the rubber base to be a bit stiff. Most customers would recommend it for its value, superior to comparable products.

Breathers didn't fit into valve covers

Previously, I have used these breathers on my Billet Specialities tall valve covers for a 1990 Chevy small block, but I wanted to replace mine. I ordered four of them. They would not fit into the holes in the covers. I complained, and I was sent four replacement breathers, but they also didn't fit into the holes. The rubber base seems too stiff (too old?) to squeeze into the holes. Perhaps I can use them on another engine.
