Customer Question

Changed an already dpf deleted 08 acert to single turbo, turbo seals started blowing oil in 7k miles, sent the turbo in for warranty but mechanic suspects excessive crankcase pressure. Went to check filter and there isn't one. Engine uses no oil and runs good. Has a couple other oil leaks that indicate high crankcase pressure. Any way to reduce pressure without changing topend to 6nz?
JA: What's the make/model/year of your truck? Engine type?
Customer: 08 pete 389, c-15 acert

Thanks for asking your question. I will try and help you out.
Unfortunately if there is high crankcase pressure. There is no easy way to reduce the pressure. I am sorry. I wish there was.
As I am sure you know. High crankcase pressure is caused by worn cylinders, worn air compressor, worn valve guides, or a faulty turbo.Please reply back if you need more help or have more questions. I am happy to assist.
