I have one for the passenger side. I just recently went over 1,000 miles. Took it out and looked inside. There was about 1/10 of an inch of oil inside it.

I have the JLT, it was cheaper and more compact than the than the Moroso.

2500 miles and emptied twice. First time (afterabout 1500) it was almost half full. I about crapped myself. 500 miles later it was pretty low. Way too much though for so few miles.

Jlt,passenger side (which I had been told was the necessary on for na engines).

Here's what I gathered from the two.

The JLT:
Is an inline separator.
Uses OEM style clips to snap into intake and valve cover.
Has a reservoir that can be unscrewed and cleaned.
Comes in polished aluminum or black.

The Moroso
Has a mounting bracket allowing you to mount away from the motor.
Uses a drain valve at bottom of separator.
Uses standard hose and clamps to connect to manifold and valve cover.

Personally, I went with the Black JLT. It was simple to install and easy to clean. I do plan to buy another one for the driver side but I just haven't had the chance. Hope this helps OP.

I have the JLT. It's a necessity on the passenger side. If funds allow, I may put one on the drivers side down the road sometime. The thing about the JLT that sold me was the ease of install. It took me longer to get it out of the box than to put it on.

I went with Moroso. I didn't like the idea of the can just hanging in space. I expect they both do their job about as well as the other.

I have seen several threads on issues with the JLT (not totally sure the design has been revised to address them), but not one on the Moroso.

Can you post a pick of your Moroso installed? I'm curious to see where you mounted it.

I don't have a pic of mine yet, but look at the customer photos here: Moroso Mustang Air/Oil Separator (11-13 GT) 85485 - Free Shipping!. That's what it looks like. Install was easy; perhaps a little longer than a JLT, but nothing difficult aside from shoving the hose onto the PCV fittings. I grabbed a couple of new ones from Ford & set my stock hose aside so I can go back to stock if I ever needed to.

Both Passenger side. Black one is JLT and Chrome one is Moroso. Got each at american muscle for 114.99. First i got Moroso for 120 miles and it caught a good amount of oil, i was surprised. i switched to JLT for 150 miles and it caught just a little less than Moroso. Moroso have a nice design, material, big can but you need to switch to a stronger/braided hose, make cuts, installation takes a while, even tho i got jegs braided hose, the hose didnt resist, as a temperary fix i used electric tape to stop vacuum leak. jlt uses factory hose/pcv connectors and takes 30 seconds to install. what made me stay w/ JLT was its simplicity, fast installation, stock hose/pcv connector. but seems like moroso does a better job keeping oil in the can, a little better filtration. Moroso drain doesnt really empty out the whole oil inside the can because of its 90 degree shape pipe. I drove the car equally the same, sort of hard, took me like a week to put 150 on the jlt and 1-2 days to put 120 miles on moroso. Maybe Moroso filtered better because of its bigger filter. I still recommend JLT over Moroso because you dont have to make any cuttings, u dont have to worry about ordering a good 30-40 dollars braided hose. If moroso came w/ stock hoses and pcv connector i would go back to Moroso. With Jlt my car idled the same as with stock hose, with Moroso engine idled a little lower. Some people wont even notice, it was just a little lower. With Moroso i kept checking the fittings all the time, checking for leaks, with JLT i only check it to empty out the oil. You will be fine w/ either one. If you dont mind the cuttings/extra work and money buying new hose for moroso can, go for it.

I had a JLT, one of the fittings broke while driving.

Switched to Moroso and never looked back!

1. Can someone explain to me the main purpose of an oil separator? What is its function?

2. Do you recommend having one for both driver and passengers sides? And why one over another in importance?

Thanks

A separator won't stop all the oil from getting into the intake. Breathers will.

So I did some reading in the SVTPerformance site about the oil breather. I still don't understand why they work better than the catch can.

That simple huh? Thought there was more to it than that. They breathers well allow oil to enter the engine bay though right?

Also, this might be a stupid Austin but what do you do with the oil that ends up in the catch can?

If you do not clean the breathers they can make a mess. I have never ran the seperator so im not sure. I dont see why you couldn't return it to the engine.

Most people just pour it out. But I have breathers and I just clean them every time I change my oil.

Ok, never knew of this issue. So the breathers or seperators are to prevent oil getting into the intake? Sorry for the newbie question but never heard of this. How is the oil getting in to the air intake?
