Hi,i have a 200,000 Mile 2006 Toyota Prius with oil blowby through a new PCV valve that goes in the hose to the throttle body intake into the motor burning oil is this because of stuck piston rings or worn rings causing this blowby?, I installed an oil trap so I don't destroy my catalytic converter, I use 5w-30 Valvoline Max life High mileage Synthetic oil, can I use high zinc motor oil or other oil, let me know how to keep it going.
You likely have troubleshooted the prius more than me but have you tried using engine restore like the EPR hybrid before and oil change to see if it helps? I plan on doing it on my next oil change.
I heard of EPR hybrid additives, it's a flush that cleans the motor, this car doesn't lose much oil since i keep clean oil in it seems to help
