2001 Toyota Highlander SUV V6 4WD 4dr SUV (3.0L 6cyl 4A)
Toyota run around
 I purchased a 2001 toyota highlander from toyota financial in september 2011. The highlander has 110000 miles on it and it has a lot of oil blowby near the PCV valve. I heard there was a sludge issue with these vehciles so I went to Libertyville Toyota and asked them to check it out. I told them i was adding a quart of oil every 500 miles and I said they should check the PCV area because I heard the sludge build up was in an unusual area of the engine. We removed the PCV plug and stuck a tube in the engne area and pulled out alot of sludge. dealer teck called and said NO Warrentee because the engine was clean. They did not check PCV area, they said I would need to pay $400 first.
