The crankcase ventilation system vents engine pressure and separates oil from the vapor. When the CCV breather clogs you get whistling, oil in the intake, and rough idle, and it can even blow out seals. We replace the CCV element and check for related oil leaks.
What this service includes
- Inspect the CCV breather and hoses for clogging
- Replace the breather element or valve as needed
- Check for oil pushed past seals or into the intake
- Confirm idle quality and no whistling
Signs your Sprinter needs it
- Whistling or hissing at idle
- Oil residue in the intake or turbo piping
- Rough idle or leaking crankshaft seals

Frequently asked questions
Can a clogged CCV blow out a seal?
Yes. Trapped crankcase pressure can push oil past the crankshaft or camshaft seals, which turns a small breather job into a bigger leak repair if ignored.
How do I know the CCV is bad?
Whistling at idle and oil in the intake are the classic signs. We confirm with a pressure check before recommending the service.
