A massive oil leak near the front of the engine. I heard engine loud ticking while drive 70mph. There are low oil level flashes, the check engine light stays on, and you smell burning oil from the engine bay.
Toyota uses cheap rubber line for the hot oil return line, designed to fail catastrophically, and possibly cause engine seizure if driver is not aware.
