JLT Oil Separator Install
I just received and installed my new JLT Oil Separator today. It took longer to snap a few pictures than complete the installation. I won't go into depth on the installation because it's just not necessary.
The JLT separator comes fit with all the hoses and quick connectors needed for installation. It's very well made and looks right at home under my hood with my existing Scott Drake Billet caps.
OE PCV line

I left the oil cup off for installation
Installation complete
Here is a picture of the old PCV line, the picture doesn't really show how much oil and crud was in it though.
The instructions recommend removing and checking for oil every 1000 miles which I'm not sure is needed.

The separator keeps oil from entering the intake.
"During the process of venting crankcase pressure back through your intake track, large amounts of oil, in the form of vapors, can coat your blower rotors, intercooler fins and even dilute your gas, lowering its octane level. This happens on all engines and is even worse when supercharged as crankcase pressures are increased."

"Is That True"
FYI: Word out there has it that the oil separators also help to slow down that sticky carbon oil crud build up on the earlier S-197 V-8 engine spark plugs too? Can anyone here using them now verify that one for us here gang?

After installing it, it looks factory, no clamps. When I ordered mine, guy I talked to said they bought new lines from Ford and simply cut the line and inserted the seperator with factory type crimps. With the factory clips it literally takes less than 30 seconds to install.

Just ordered one....this is the best kind of advertising there is. (and those chrome valve covers are slick)
I was considering MacGuyver-ing up a RACOR unit. It was likely major overkill but they are pretty well known in marine and diesel use to perform quite well. However, this one looks pretty solid, and is obviously well thought out. SOLD! Thanks for posting.

Hey everyone, this might be a silly question, but would installing this oil separator on a car that isnt supercharged be beneficial? If so, should it be a mod that I add to my list?

I can route it back into the intake with just a hose and pull the filter off, if needed for inspection. My car runs better without it into my intake system.

On my 2010 with 13k in miles I just checked my hose, and the thing was pretty filthy. I took a rolled up paper towel to it and cleaned it out a good bit... after seeing this thread and my own piece, I'll probably spring for one of these pretty soon.

In case anyone's interested, this seperator really works. Put mine on Saturday, took a 110 mile cruise on Sunday and just for the heck of it, checked the seperator. Had about a teaspoon's worth of oil in the bottom. My Mustang is a 2007 with just under 20,000 miles on it, change oil and filter every 3500-4000 miles, Mobil I synthetic and Ford filter. Always lost a bit of oil between changes, and now I know where it went-right to the combustion chamber where it could give the plugs and pistons a nice build-up of crud.

It ran 119.00 from JLT, with free shipping. They offer several options as far as finish and right or left side. While it may seem high, its a quality piece and looks like a factory installed piece, not something put together with hoses and clamps.
As far as the syn oil, I've noticed on various cars I've had in the past (always used syn oil) that some use a bit and some don't. My Taurus uses a bit but my wife's Subaru Outback stays full. Point is, the seperator really showed me what was going back into the intake, and now what isn't.
