I have looked online and in the manual for a service interval for the ccv on my 21' F450 6.7. It has the screws, thus making it serviceable (It looks like DRWs has serviceable filters, SRWs do not) according to a thread over on FTE. The consensus is the serviceable filters can start to plug as early as 30k miles. Several posters seem to blame the plugged filters on upper oil pan leaks.
CUMMINS intervals are 67,000 miles...
What's the Ford interval on the CCV for the serviceable one?
