Hello everyone. I'm Erkan. My car is a 206 1.4 gasoline engine. Today, I tried to remove the MAF sensor without removing the crankcase ventilation hoses to clean it. Of course, the short hose between the top cover and the PCV valve broke. I've taped it up for now and will take it to the dealership tomorrow to have it replaced. Would it be safe to use it during this time? Thanks.
