Today was a beautiful day out so I pulled both of the tops off my ford oil catch cans on my GT350. To remove the top you need a 4mm Allen wrench. It's a very easy process. When I remove the hose from the driver side can that goes to the intake tube I noticed the green o-ring was split and the yellow o-ring had a knick on it. Luckily I still had the stock breather line that I stole both o-rings from. Easy fix. But just to let you all know, the green o-ring goes in first then their is a black plastic ring that separates both o-rings.
