How to Install an Oil Separator for a 2005-2010 Mustang GT

Installing the JLT Oil Separator is one of the easiest things you can do for preventive maintenance on your 05-09 Mustang. The separator works by trapping the oil vapor that is released back into the crankcase via the Ford PCV system. Ford designed it this way so these oil vapors would be burned off during combustion but in actuality it can cause sludge to build up and carbon deposits on several places in the internals of the motor. By upgrading to this JLT unit you will help to keep your engine as clean as possible.

First open your hood and locate the PCV line that connects from the valve cover to the manifold on the driver’s side of the engine.

Once you have identified the PCV hose find the green tabs on the ends and push to release. Next step is to then remove the PCV hose. Pull up on the portion of the hose connected to the valve covers then fully remove.

Now would be a good time to take a look at the PCV hose you just removed to see just how much oily mess ends up in just the hose imagine the rest of the internals…

The JLT Oil Separator comes with factory OEM type fittings which help to make this such an easy install. Identify the correct orientation of the separator lines and snap into place in the same manner as they were removed.

Now screw on the actual oil container and place in between the electrical lines for a clean finish.

The capacity of the separator should allow you to remove and discard the oil just about every oil change (about 5 000 miles). I would monitor the separator every 1 000 miles at first just to see how much is being collected.

Now take a spin and figure out what your next Mustang mod will be……
