Common problems

Crankcase blow-by

What is crankcase blow-by and oil use, and why are they bad?

Crankcase blow-by occurs when gases escape from the combustion chamber into the crankcase, often due to carbon and sludge buildup. This causes excessive oil consumption and engine wear. Over time, this leads to poor engine performance and can trigger expensive rebuild recommendations, often costing between $20,000 to $60,000
