$2.99 Oil Catch Can - Toyota Yaris Forums

Ok sure.

But both hoses do not do the same thing.

The set up is to pull in air form before the throttle body through the crankcase and dump it back into the intake. The hose that dumps back into the intake has the check valve. When you let off the gas the throttle body closes down most of the way and the motor would suck air though the crank case and burn off the fumes in the crank case.

But with only one you will only get blow by and a bit of air from the change in the temp as the car heats up and cools down out of that hose. I didn’t see that you had removed the other hose.
