Shopping for Oil Separator

Oil Separator Shopping Info

What Is an Oil Separator?

The blowby gases created by your car’s running engine are usually accompanied by oil droplets that can cause harm to your system when they build up. The oil separator, or air oil separator, is the component that’s in charge of separating oil from the blowby gases to avoid oil buildup and minimize the loss of oil at the same time.

How Much Does an Oil Separator Replacement Cost?

The cost of an aftermarket oil separator replacement ranges from around $10 to over $400. The price is largely determined by the complexity of the oil separator, which depends on the model of your vehicle. Getting the oil separator replaced by a professional can cost you an additional $100 to $200 for labor depending on your location.
