Oil Separators And PCV Systems

You may have heard from some that an oil separator should be one of the first mods to get for your Mustang. In a lot of cases, that’s completely true. This is due to oil blow-by coming off the crankcase being released back into your intake.

As part of your Mustang’s Positive Crankcase Ventilation (PCV) system, there is a line that connects the crankcase back to the intake tract to release excess gases back through the engine. A way to recycle unused gas fumes, in a way.

The problem is oil sits in the bottom of the crankcase and can be kicked up during high-performance driving conditions. When these oil vapors are picked up and sent through the PCV system back into the intake, oil can coat the linings of your intake, throttle body, and the interior of your intake manifold which could drastically reduce efficiency. This, in turn, could result in a loss of power, diluted gas and lowered octane level.

Oil blow-by is worth noticing on naturally aspirated engines, but is drastically increased on turbocharged and supercharged engines.

How Does An Oil Separator Work?

An oil separator is essentially a filter that sits in between your Mustang’s crankcase and intake that will filter the oil out of the vapors traveling to your intake. Most oil separators that we sell here at CJ’s come in a kit that will replace the hose entirely for a quick and easy installation.

The advantage of installing an oil separator on your Mustang is that you can rest assured that your intake tract isn’t getting caked with oil. An oil-caked intake tract can not only result in reduced efficiency but also a safety hazard. Without an oil separator on a car that spends a fair amount of time in the high RPMs, this oil can cake up around the throttle body. This can mean your throttle body could trip a check engine light due to lack of response or could potentially get stuck open or closed. Which most definitely isn’t good.

Mustang Oil Separator Highlights:

  • Less Oil Blow-By, Equating To Longer Engine Life
  • Minimal Oil In Intake Tract, Allowing For Full Power Potential
  • Best For High-Revving Engines, Both Naturally Aspirated & Forced Induction Variants

Oil Separator Maintenance

An oil separator, or catch can, will filter out oil and collect it in a small reservoir for easy maintenance. It’s generally recommended that you check your oil separator every 1,000 miles after initial installation in order to gauge how often it will need to be emptied. Some driving styles may warrant a check more often than others. Once you find a groove that works for you, you’re good to go!

Most customers have informed us that they check theirs every 3,000 miles for a regular street car. And for those who take their Mustang down the dragstrip, it’s recommended that you empty at the end of each run. Keep in mind, the larger the reservoir, the more it will hold. So, be sure to check with the manufacturer’s instructions for a more detailed maintenance schedule.
