So today I did a few highway pulls on the way home from work and started smelling oil, so when I got home I opened my hood to find my oil cap was missing. (I know I know....don't rag me on why it was missing,I either forgot to put it on the other day or it vibrated off). Now the thing is the car felt like it had more power and no more 4k rpm "stumble". I have an all stock motor except a drop in filter, downpipe, and a blouch 440xt....and no tune. Was it just me or did my car run A LOT better vented to the atmosphere.
So the BIG QUESTION is, should I go to an AOS or catch can??? Or am I crazy and it really doesn't make a difference? Also maybe the aos or catch can would prevent my normal blow by?.
