10 Buick New Regal gas inlet front oil pipe

I have already discovered this problem. For the machine with the same model 2.0, 1: It is recommended that you check whether the bonnet waste valve is faulty. 2. If the bonnet waste gas valve fails, you can install an oil breather to avoid it. 3: It is also possible to directly exhaust the valve, but the small tube of the intake pipe should be blocked.
