Erick:
Vehicle: 2007 Toyota Solar 3.3L V6
Task: PCV Valve replacementI’ve located the PCV valve; rear manifold, facing firewall, mounted horizontally.
There are several (hosed) connections in the way of positioning my wrench onto the
hex PCV valve. Would appreciate your advice as to what components I can disconnect
to gain better access to the valve.Thanks,
TributeOne

Karl: Re: PCV Valve Access, ’07 Solara, 3.3L V6
The 19mm wrench is not the issue; should you have photos of the 3MZFE V6 engine, you will note there are several components in and around the PCV valve such as a vacuum pot, some other hoses, etc. Those are the items I need help with. Can you advise me which ones I can temporarily remove to gain leverage for removing the PCV valve?
Honestly I’m not familiar with that engine. If you could post a pic I might be able to help.
Just out of curiosity, why are you replacing the valve?
Eric: Re: Location of PCV Valve, 2007 Toyota Solara 3.3L V6
Note attached engine pic taken from the front bumper, LH side is passenger side.
You will see a metal vacuum pot at Left rear in pic. Also note hose just to Left
of that vacuum pot. Below, and to the Right of vacuum pot is PCV valve screwed into
rear exhaust manifold. Some of these components are in my way. Other than the vacuum
pot, can I remove the other hose, or something else that your aware of?Answering your Q: Bought the Solara (convertible) new in 2007; great car. With all my cars,
I keep them for quite some time; do not lease. I perform preventative maintenance such as
cleaning Mass Air Flow Sensor, Idle Control Valve, Throttle Body, engine and cabin air filters, belts and hoses if needed, change out of fluids, ignition coils and plugs if needed. The PCV Valve, if clogged, can affect overall engine performance and fuel economy as well as throwing a Code. I would prefer to replace rather than clean as I would have to remove it anyway. (Are you able to view the attachment?)TributeOne

Eric:
WERE YOU ABLE TO VIEW THE JPEG ATTACHMENT I SENT?
IT SHOWS THE TOYOTA SOLARA 3.3L V6 ENGINE AND THE
AREA WHERE THE PCV VALVE IS LOCATED.I STILL NEED YOUR ASSISTANCE REGARDING THE DISCONNECT
OF ADJACENT COMPONENTS TO FACILITATE GETTING TO THE HEX
OF THE VALVE FOR REMOVAL AND RE-INSTALLATION.TRIBUTEONE
Eric:
Here is a pic of the area behind the manifold, near the firewall
where the PCV Valve is threaded (horizontally) into the manifold.
Can you see it now? There is a vertical hose and other stuff in
my way. What can I move to get at the hex?TributeOne
The silver tube at the lower left is an A/C line from the evaporator (definitely do not disturb this)… I suppose that is why Toyota requires a special tool to unlock the plastic coupler.
The left arrow is pointing to a common ground. Can be disconnected with no issues, just make sure to re-attach all the ground wires.
The Hose like things under your right arrow are spark plug wires (this uses a waste spark system). Simply move those to get access.
The vacuum assembly (round thing with the rod) can be removed with two screws and moved around to provide access, just re-install..

Replacing PCV’s as preventative maintenance is pretty much something of the past. You might consider that in the future. It may save you some headache.
As for the valve on that vehicle I don’t think you need to remove anything, you just need better tools. I use a long pair of pliers to remove those to replace them. Otherwise you can remove the fasteners for the upper intake, leave everything connected, and move it up so you can gain access. That’s how I do plugs on that engine anyway.
