Thank you for choosing JustAnswer and allowing me to help you resolve your Lexus questions!
Have you removed the front valve cover to check for excessive sludge build up?
Thank you. A couple more questions:
1. Why does it burn oil on longer trips but not burn oil locally even though I go 70mph locally for short distances? Is it a crankcase pressure issue?
2. Do you know approximately how much putting new valve covers on it would cost?
