As PowerDemon mentioned, a defective PCV valve could be the reason your RMS is leaking. I had similar issues: leaking RMS, rough idle (misfires) and oil around the oil filler cap. A new PCV valve fixed the misfires and the car runs great now. Well worth the money.Probably, probably not. I'm gonna b leaking for a month tbh. It's a slow leak. I'm broke asf. Just did the spark plugs to see if that helps with my misfires. There's always something popping up smh.
I don't understand how the RMS is leaking when it was perfectly fine for 4-5 months with 0 leaks. Did the seal just give up? Hard driving could cause this? I'm honestly in shock how this shit is leaking randomly. Could it be anything besides the RMS?
