Hi all new to this forum but not new to Toyota’s I presently own 2 others and have owned 5 previous To that. I have just purchased a used 2004 Manual 2.4 lt 4 cylinder 4 door wagon with 321k on the clock. Problem I have is that their is a serious knocking (rattling) when the the engine is under load, and a solid thump in the gear box when changing gears. The car is not blowing any smoke of any description. Has anyone any ideas. Thanks in advance Scott
