Hi as a new member to this forum I recently bought a 1954 Mk5 that has been off the road for a few years but is complete, I am slowly going through things I checked the oil and it looks good but will be replaced as a matter of course, my question is the maintenance guide on this forum says the oil pump should not be removed from the engine unless the crankcase is apart ,it also says to regularly clean the filter ?.Is it a no/no to remove the pump from underneath to do this filter clean
