Guys...I need to get some opinions/advice on this. I recently opened up my hood to clean the air filter and noticed the crankcase ventilation hose that connected to the air filter box was disconnected. I don't know how long its been that way, but I haven't ever noticed any issues with the engine. So, I reconnected it back to the intake and since then, I've noticed a couple strange things. First, my exhaust seems to be louder and resonate more in the cabin while in the mid-RPM range (maybe 2-4k rpm). Not only is it slightly louder, but it also has a bit of a different sound in that range as well (more throaty). I've had a magnaflow 22" muffler on the truck for a couple years now and it definately sounds different after I reconnected the hose. Also, my gas mileage according to my dashboard has dropped from around 14.5 mpg to between 10-11mpg. Lastly, the truck now seems to shift differently like it wants to remain in a gear longer and i feel like there's maybe slightly less power.
It's my understanding that this hose vents excess gasses from the crankcase into the air intake which is then re-fed back into the engine to be burnt off. I don't really understand why reconnecting the hose would have any effect on the sound of the exhaust or the engine performance.
If someone would kindly help me out with their opinion and advice, i'd greatly appreciate it!
