Problems with filter housing usually come with a fan belt slipping noise we changed the factory fitted part which was a Ford part to a part we bought from a Ford dealer which was a volvo part then the oil pressure switch blew so replaced that then the dipstick oil seal went so replaced that ,did lose a lot of oil then but went better than ever once all that had been done but got about ten miles from the garage and the clutch went when I tried to change from 6th to 4th I think but won't go into gear just 1st to 3rd when switched off won't go into any gear when engine running
