To Kyle from Roush & others:

As you are likely aware "Oil Separators" are now being sold for the 5.0L! Are they necessary on a 5.0L "with or without" a Roush Supercharger? Do I assume after all this time Ford hasn't dealt with some oil vapor problem.... or they just one more thing we can buy.... that may not be really necessary!

 

I just put 2 on my GT350 with 1200 miles on it. The inside of the hoses I removed were wet with oil.
