Be wary of any 4cyl in a truck. Higher compression more likely to blow head gasket, more carbon buildup piston slap, WAY underpowered. No, it won't happen for a while, but if you want the truck for a long time . . . Bottom line is the engine has to work that much harder than a 6cyl. I know that toyota has upped the displacement since the 22re over the years, but I still wouldn't buy one
