Default Pcv valve problem pleaseeee help

Guys Please help.

I bought 2004 rx330 with 100k runaway. Car is fresh and in a good condition.

Next day i noticed that bluish smoke was coming from exhaust. i checked oil and 2 liters were eaten by engine in 2 days. I got mad.
Then one guy disconnected pcv valve from hose and suddenly smoke and eating oil stopped.
The engine is not eating anymore oil. Then i bought new pcv valve 3 pieces i have changed 3 of them but nothing helps bluish smoke and eating oil engine begins. When i dissconect hose form valve, valve is oiled.

Any idea please help. Also car engine light and vsc came on and computer told P0430.

Car is running smoothly when disconnect hose from valve no smoke no oil eating.

Too many unknowns to try to help you.

Best bet to check in the car for a check up with your local Toyota guy.

And welcome to CL.

See this link for a starting point.

I do not think you are familiar with what a PCV valve is. It is a ventalation valve that allows gasses to escape but those gases are designed to be put back into circulation through the intake.

You likely have a CAT Converter issue which is causing the car to run really rich.

Lots of variables but the link is for the code you are suggesting. Start there. See if you have any other codes too.
