Get a Quote via WhatsAppSend an Email InquiryWhat Is the MAN 51018040044 CCV Filter?
MAN 51018040044 and 51018046002 are the crankcase ventilation (CCV) filter references for MAN commercial trucks. The filter is installed in the crankcase breather system and removes unburned gases and oil vapour from the crankcase before they are recirculated back into the intake manifold. Failure to replace the CCV filter on schedule can lead to increased crankcase pressure, oil leaks, and reduced turbocharger performance.

Vehicle Compatibility
Maintenance
| Condition / Trigger | Action |
|---|---|
| Scheduled service interval — every 20,000 km or annually | Replace as standard service item |
| Increased engine oil consumption | Inspect the CCV filter — a blocked filter cannot return oil vapour to the intake |
| Oil contamination in the intake manifold | Replace the CCV filter and clean the intake system |
| Signs of excessive crankcase pressure | Replace immediately — elevated pressure causes gasket and seal failure |
