Thanks for the info, [email protected] This is my first experience with open breathers so I was more curious than concerned but I couldn't seem to find any comparisons. Apparently I didn't look hard enough.

Forgive my ignorance on the subject, but how does Ford & Chevrolet handle crankcase ventilation on Shelbys and LS Corvettes with SC engines? What does Roush do?
