Hello everyone I’m new on here and need some help. My car was running rough as hell so I cleaned the maf sensor. Change my intake, changed oil , and changed spark plugs. But now car is misfiring and leaking oil out of the rear passenger side of the engine I’m not sure where it’s coming from? But it’s dripping on the downpour if that help. Also have the PO300 check engine light. Which is why I changed everything I did. Thank you for your time anything is appreciated!!!

 

Could be the passenger side valve cover gaskets going bad. Probably time to replace the oem covers with some aftermarket ones (with oem gaskets)!

 

Can you change them from the top or does the whole engine need to be pulled? I can’t see any oil on top side of engine bay.

 

The misfire might be because you mixed up the #4 and #6 coil pack wires when you changed the spark plugs. The way the wires are oriented, its easy to mix them up. Its happened to a lot of people, myself included.

 

thank you. I will have to check when I get home. Didn’t think about this.

 

this wasn’t the problem. Still don’t know.

 

So u mixed up # 3 and 5 coil wires huh?

 

Get an inspection mirror and a flashlight and just look around for where the oil is pouring out. Might have a cam sensor came loose and it's just pouring oil out of the hole.

 

Yes I did. Now the leak of oil is way slower almost not noticeable. But car feels weak so I don’t know what it could be. No codes are being thrown now. How should I go about the power issue?

 

I ordered a endoscope so I will know soon
