Does the 98 rav4 have a zero clearance engine?

The 1998 Toyota RAV4 does not have a zero-clearance engine. Generally, zero-clearance engines are designed to prevent valve-piston contact in the event of a timing belt failure, which is more common in performance-oriented engines. The RAV4’s engine is more traditional, and while it is reliable, it does not feature this specific design characteristic. It’s always advisable to maintain the timing belt to prevent engine damage.
