Yes, a blown turbo can indeed cause crankcase pressure to increase. When a turbo fails and starts leaking oil into the exhaust system, it can also pressurize the crankcase by allowing exhaust gases to flow back into it through the oil return line. This scenario can lead to a range of engine problems such as oil leaks, increased oil consumption, and reduced engine performance. Addressing a blown turbo promptly by having it inspected and repaired by a professional is crucial to prevent further engine damage.

FAQs & Answers

  1. What causes crankcase pressure to increase? Crankcase pressure can increase due to engine issues such as a blown turbo, which allows exhaust gases to enter the crankcase, oil leaks, or clogged ventilation systems.
  2. How does a blown turbo affect engine performance? A blown turbo can cause oil leaks, increased oil consumption, and reduced engine power, ultimately leading to poor performance and potential engine damage.
  3. Can exhaust gases enter the crankcase from a failed turbo? Yes, when a turbo fails, exhaust gases can flow back through the oil return line into the crankcase, causing increased pressure and engine problems.
