Yes, a turbo can cause Blowby. Blowby occurs when combustion gases escape past the piston rings into the crankcase. A turbocharger increases cylinder pressure, which can exacerbate this issue if the piston rings or cylinder walls are worn. Regular maintenance and using quality components can help mitigate the risk.

FAQs & Answers

  1. What is engine blowby and what causes it? Engine blowby happens when combustion gases leak past the piston rings into the crankcase, often caused by worn rings or cylinder walls.
  2. How does a turbocharger increase the risk of blowby? A turbocharger raises cylinder pressure, which can worsen blowby issues if engine components like piston rings are worn.
  3. Can regular maintenance prevent blowby in turbo engines? Yes, regular maintenance and using quality engine parts help reduce the risk of blowby in turbocharged engines.
  4. What are symptoms of blowby in a turbocharged engine? Common symptoms include increased oil consumption, smoke from the crankcase ventilation system, and reduced engine performance.
