What does the crankcase vent filter do? The crankcase vent filter is used on high performance engines such as race car? though it is Œćused on older models of vehicles as well. Inside the engin? small amounts of combustion gases push by the piston in the cylinder and enter the crankcas? or the bottom end of the engine. These gases create a positive pressure inside the crankcas? which needs ventilation. Positive crankcase pressure robs the engine of power as the pistons have to fight against that pressure when performing each down stroke?A breather tube is mounted at the top of the crankcase in the engine block that releases the positive pressure into the environment or into the intake to cleanly burn them before they enter the atmosphere. The breather tube contains a port or elbow at some point along its route where the crankcase vent filter is installed. How do you know you need the crankcase vent filter replaced?

"I'm a big fan of this incredibly convenient service! GoWrench staff do a great job and respect your time, unlike the nightmare that is involved in visiting the dealership/auto shop just to get your tires rotated or oil change. I shouldn't have to lose a day of work, two times a year, just for regular maintenance & tire swaps -- and with GoWrench, I never have to deal with the patronizing, dirty, and time-consuming service at the car dealership or auto shop, again!"
