Good evening everyone, name's John, I'm a 23 yr old journeyman level mechanic that generally works on Japanese imports, hence the cringey name.
My sister owns a 2011 Chevy Camaro RS with the 3.6L V6 engine, and i just wanted to ask some questions and see if i could get some solid answers from y'all.
So she has a leak coming from the right (driver side) PCV valve as well as a leaking valve cover gasket and oil seeped into her spark plug holes and caused the cylinder 3 coil pack to fail and cause a misfire and flashing check engine light.
I replaced the coil pack and its running fine now, no codes, but the leaks and oil in the spark plug cavities is still a concern.
I plan to replace the valve cover gaskets and the PCV valve and hose and use an evac pump to suck the oil out of the holes before unscrewing the spark plugs on Sunday. The PCV hose connected to the right side valve is inundated with oil leaking from the valve and its collected a concerning amount in her air intake tube so it will be replaced as well.
Doesn't seem like it made it farther than the intake tube as the throttle body is clean, so I'll count our blessings.
So i was wondering, as far as the right PCV valve goes, would I need to remove the valve cover to replace it?
Any links to relevant forum posts or videos on replacing it or any educational materials are greatly appreciated, as she has finally entrusted regular maintenance of the vehicle to me.
