Seafood is a staple in nearly every Chilean's diet. Shellfish such as loco (abalone), erizo (sea urchin) and piure (an unusual red invertebrate) join more widely known fish, including sardines, salmon, congrio (conger eel) and atÃºn (yellowfin tuna).
To work efficiently, pipes need a way of regulating how much fluid can pass through them; they also need a way of switching the flow off completely. That's the job that valves do: valves are like mechanical switches that can turn pipes on and off or raise or lower the amount of fluid flowing through them.
The purpose of a valve job is to resurface the poppet valves and their seats, which control the flow of air and fuel to move the pistons. On newer engines (V6 or V8), a valve job can cost up to $125 per valve that needs repairing, with the cost increasing for engines with over 12 valves.
