The same thing just happened to my 2001 4.4i here in the U.S. I started getting this tin lizzy noise, drove down the freeway about 12 miles and when we opened up the oil filter housing the filter was filled with metal flakes. My technician feels since it still runs good that he will be able to fix it. He says however, do not get Made in China oil filters. The one I have had some holes in it so some of the metal has probably passed through.
