Hi, my 182 has got a very loud rattle like noise from the engine.. I tuk it to an engine garage & they said it's coming from the bottom part & it's the camshaft bearings,but as they attached to the engine they can't check unless I get the work done.plus change the dephaser at same time.. I went for 2nd opinion from renault who said it was coming from the top part of engine & it's cam followers & recommended engine flush, if that don't work (Which it didn't made it worse!!)then it's cambelt dephaser & replacement set auxilliary... For £1500! Does anyone have any knowledge of this plz as now I'm confused!
