Crankcase Ventilation CCV Service in Riverside, CA
Stop oil in the intake and a rough idle caused by a torn crankcase breather.
Crankcase ventilation CCV service for your Sprinter cures oil in the intake, whistling from the valve cover, and rough idle from a torn breather diaphragm. We test crankcase pressure, replace the CCV valve or valve cover breather on OM642 and OM651 engines, and check for related oil consumption, so a hard-working delivery van keeps its intake clean.
What this service includes
- Crankcase pressure test to confirm a torn diaphragm
- CCV valve or valve cover breather replacement
- Inspection of the intake for oil pull-through
- New valve cover gasket where required
- Check of oil consumption and related fault codes
- Fault memory clear and running verification
Who this is for
- You hear a whistle from the valve cover area
- Oil is showing up in the intake or turbo piping
- The engine idles rough with a breather fault
- Oil consumption has climbed with no visible leaks
Frequently asked questions
What does the CCV valve do?
The crankcase ventilation valve routes blow-by gases back to the intake while trapping oil. When its diaphragm tears, it pulls oil into the intake and unsettles the idle.
What are the symptoms of a bad CCV?
A whistle from the valve cover, oil in the intake piping, a rough idle, and sometimes higher oil use. We confirm it with a crankcase pressure test.
Is it just the valve or the whole cover?
On some engines the breather is a serviceable valve; on others it is built into the valve cover, so the cover is replaced. We tell you which your engine needs.
Can a bad CCV cause other faults?
Yes. Oil pulled into the intake fouls the EGR, swirl flaps, and MAF over time, so fixing the CCV early protects those parts.
