[QUOTE="RaYzerman19, post: 1299461, member: 18388"] Valve adjustment is independent of the CCT. The CCT has a spring that simply keeps tension on the cam chain as the engine turns. A weak CCT can lead to the chain jumping a tooth or two, which then alters cam timing, which will likely lead to a valve hitting the top of a piston...... being the CCT was redesigned in late 2007, better stronger spring, it is advisable to change CCT's on prior FJR's. You will probably notice a loose chain, but it may be masked by other sounds..... and when it is loose, you don't know how loose.... personally, I'd change it without hesitation before it gets that far. Newest CCT has a green dot. [/QUOTE]
