Turbo Engine Repair

How a turbocharger works

A turbocharger sits between the engine and the exhaust. Exhaust energy spins a turbine on the hot side, which drives a compressor wheel on the cold side that forces compressed air into the engine. More oxygen in the combustion chambers lets a smaller engine make more power and use less fuel.

Protect it with oil changes

Turbo engines are hard on motor oil: the hot side can get visibly red hot and the shaft spins extremely fast. Follow your manufacturer’s oil and service recommendations closely. Late oil changes can shorten turbocharger life.

Signs of a failing turbo

• A whine that grows louder when boosting, and can become a howl
• Burning oil or coolant in the exhaust
• A lot of oil in the intake
• Sudden loss of power
• Blue smoke from the exhaust, which points to oil; white smoke can indicate coolant

Repair, rebuild, or replace

Turbo failures usually trace back to oil supply, contamination, or wear. Depending on the damage, the turbocharger may be replaced or rebuilt, and rebuilding takes machining and balancing that a professional should handle. After a failure, the intercooler and intake tubes should be cleaned thoroughly so debris does not cause a second failure. Bring your turbocharged vehicle to any of our Long Beach or Bellflower shops.
