Question
what do you mean by "1.6 litter valve"? and what is mean by line engines ?

Answer
1.6 liters is the size of the engine displacement.

There are many different types of engines on the market today, but more specific to cars/trucks is either "in-line" or "V" shape.

In-line engines are just what they are, i.e. an in-line 4-cylinder engine has all 4 pistons in-line with each other.  A "V" style engine is like a V-6 or V-8, meaning if you've got a V-6, you've got 3 cylinders on each side of the motor, connected in a "V" shape.  :)
