Hello , my name is Joe

I have read your question and will do my best to help.

There are 3 main factors that can result in excessive blowby in your engine: Internal engine damage , a malfunctioning or defective air compressor , or a malfunctioning or defective turbocharger.

There may have been dirt or dust entering the engine from a small gap in the air filter boot or tubing.
You can visually inspect for any of the following:

1. Loose intake clamps between the air filter housing and the turbocharger inlet.
2. Worn, loose, or broken air housing latches/clamping hardware.
3. Loose or poor fitting connection at the turbocharger inlet.
4. Collapsed or buckled intake piping.
5. Incorrect filter installed by customer or OEM. Contact Cummins Inc. if there is a question about proper filter installation.
6. Poor seal at filter (incorrectly installed, damaged filter or housing, worn latches , etc.
