So i'm doing more research about my bad MPG problem and how the car's power has decreased slightly too. I've kept an eye on the breather pipe which comes off the side of the rocker cover for the past few months now. It's really soft and squishy if you press on it and you can blatantly see it's collapsed as it doesn't have the round curved shape anymore. It looks like the pipe has just died lol.
This is the silicone version of what i'm talking about.......
Would this collapsed pipe cause the problem i'm having??
