2002 Highlander 3.0 6 cyl
I have a 2002 Highlander with a 3.0 6 cyl and 119,000 miles. It doesnt get driven much and I have been doing some work on it myself lately. I am about to pull the valve covers and check the valve adjustment. I have been reading about the oil/sludge issues with these engines and was wondering since I will have it apart, should I replace the right valve cover with a used 3rd gen cover from a 2006 Highlander with a 3.3? If so, is there any modification needed for this process, or should it install without any issues? Thanks!
