Review on Motorad MO 99 Oil Filler Cap by Ryan Lawrence

This cover is fine. However, it definitely doesn't fit as well as the original. The original snapped into place with a pleasing tactile click. It's kinda easy, stop spinning. Also, it takes significantly less effort to adjust, which makes me wonder how well it actually covers the gasket. although I now think it seals adequately. If you're the kind of person who just wants to get it over with. The cap is great for the money. If you're the type of guy who only buys the best for his car, shop a little longer and buy a genuine GM cover.
