2003 lexus gx470 overheated, no compression on passenger side of engine
Hi, I recently picked up a 2003 lexus gx470 off of my mother. it has the 4.7L tundra engine in it. She overheated it bad. melted the coolant overflow tank. anyways i did a compression test and it has perfect compression on drivers side cylinders (170psi) however, passenger side came out at (0psi) in 2, 4, and 6, and 30 psi in cylinder 8. any ideas? head gasket? or something a little more complex then that?
