OIL SLUDGE COVER UP
 Before you purchase any used Toyota with the 3.4 V6, research: "Toyota Oil Sludge" problems. Also read up on the massive recall Toyota launched to replace thousands of engines. Unfortunately, this recall did not show up in the reliability section of my trusted vehicle review sites. I bought an amazingly attractive clunkerI am not alone BEWAREI loved my 4Runner, but it will be the last Toyota I own. At 110,000 careful and certified serviced miles I need an new $6000 engine. The Toyota Service Advisor admitted there is a design issue.But nothing they can do at this time.
