Hello Everyone. So I was checking to see the K&N air filter I had installed on my 2011 Ford explorer limited edition 3.5 Liter engine to see if they are due for a cleaning. When I removed it, I noticed some oil on top of it, this would be the side between the air filter and the intake port. As I removed the baffle or the the intake hose, I see more oil residue inside. I started to clean it and checked all around if there was some oil or fluid leak that might have gotten in. So here's what I found out so far:
- possible bad PCV valve, (can anyone tell me where it is under the hood)
- I did not change the oil and filter soon enough. I did wait till it was around 5000 miles since last one and my "change oil reminder kept on blinking for a week before I changed it and the oil was really dark. I was told this would cause clogged channels if oil was really dirty, any advise on this one
- Lastly, which what i really don't want to find out is i could have bad piston rings and i should do a compression test, anyone know what the numbers (pressure) are for a 3.5 liter ford engine would be?
Anyhow, could really use any help anyone might throw at me. Thanks in advance
