I have a 1992 Toyota Camry with 460,000+ kilometers that does not burn oil but leaks it from the va**e cover and oil pan gaskets at the rate of about two liters per 5000 kilometers. I've been quoted $700.00+ to replace the gaskets. I'd like to keep the car for another year or so but am reluctant to replace the gaskets. I've used Va**oline Max Life for he last two oil changes with some improvement. Does anybody have any advice on how to reduce thsi leakage further?
