Ok.. I have a question.. First of all I am not a mechanic by no means, but this oil separator catches the oil instead of it going back into your engine were its supposed to be?? So if It catches oil and traps it, wont your engine be loosing some of the 8 quarts in the pan, that's required for the 5 liter engine? Just asking

The oil isn't going back in to the pan, it's coating the intake runners, valves and getting burned and shot out the exhaust. A separator just helps reduce the amount getting through and coating the intake and diluting the fuel

 

Follow your pcv lines and see where they go. One goes directly into your air intake and the other goes just behind the TB under the intake cover. The oil is not going back to the crankcase which is the problem

 

I see.. Make much more since now.. Thanks.. So is it a flaw from ford, or is it just a preference for the owner?

 

That's where the debate starts. Pro-separator or anti-separator. It's not really a flaw so to speak.

My theory is ford deemed that this wont cause THAT much of an issue to warrant putting them in at the factory. Heck, once it's out of warranty it's your problem anyway. Plus these cars have to appease to a wide range of people, not just us mod/obsessive guys. Having catch cans to empty on top of an oil change could be looked at as a hassle. And if missed, cause even more of a mess.

In the long run, it's extra insurance/protection for YOUR car. So if you want it, spend the money. If not, spend it elsewhere. Which is why I don't get why people get all defensive over them. Obviously they do work, just personal opinion of they are necessary.

 

just to prove they work...this is after maybe 100 miles???? there was about a 1/2 inch in the bottom.

 

Bought the passenger side seperator in silver finish, straight from JLT website yesterday, so it will become my first mod for the car.
