I have a 1997 Toyota 4Runner SR5 with 298,000 miles and I have owned it since 2001 used with 39k. I have always taken care of the vehicle and 2weeks before the Cruiser Classic the truck started to blow white which is usually a sign of a bad head gasket. I had the truck disassembled since July and just recentlyI started working removing both cylinder heads and found that the #6 cylinder had antifreeze. I just finished replacing both cylinder and it runs like a champ. Here are some pictures of the tear down and rebuild.
