Car Mechanics (Engine Bay (coolant reservoir- holds coolant, which helps…

- - - - engine's piston rings may be worn (fix by replacing piston rings->not DIY)
      - engine's valve seals may be worn (fix: replace valve seals-not DIY job)
      - damaged or worn valve guides (fix: replace valve guides- not DIY job)
    - - PCV system not working properly (fix: replace PCV valve)
      - engine may have mechanical problems (fix: check compression to determine engine condition)
      - engine's piston rings or valve seals may be worn (fix: replace piston rings- not DIY)
    - - transmission fluid may be entering the intake manifold through the vaccuum modulator (fix: replace vacuum modulator)
      - cylinder head gasket may be bad, warped, or cracked (fix: replace or resurface- not DIY)
      - engine block may be cracked (fix: replace engine block)
    - - if you have, carburetor choke may be stuck close (fix: repair/replace choke)
      - fuel injectors may be leaking (fix- replace fuel injectors)
      - dirty air filter (fix- replace)
      - may be some other ignition problem (check distributor cap and rotor)
    - - engine may have mechanical problems (check compression to determine engine condition)
      - ignition timing may be set wrong (fix- adjust timing)
      - engine running too hot (fix- check and repair cooling system)
      - fuel injectors may be stuck partially open (fix- replace injectors)
- - - - purpose: convert gas into motion so car can move. burns the gasoline inside the engine, making it an internal combustion engine
      - different kinds of internal combustion engines
        
        diesel engines
        
        uses the four-stroke combustion principle, known as the "Otto Cycle"
        
        gas turbine engines
      - Why is an engine called V6 or V8? number of cylinders an engine has- 3 in each bank or 4 in each bank (shaped in a V)
    - - big hole/tubes (cylinders) are cast into the integrated structure
      - where pistons slide up and down
      - more cylinders, the more powerful
