hi, I noticed that my focus 1.8 tdci 2003 engine stared to rattle like an old 1.8 I had on my Fiesta. When I bought it was really smooth that you could bearly hear the engine running but recently it became more noisy, when I say rattle I don't mean like a shell bearing failure noise just like the old diesels on the Fiesta mk3 and escort mk6. Is it a common problem or maybe I have a bigger problem than I think? It has about 85k on the clock and replaced the turbo about 5 k ago....any suggestions? I am using MPM fully sintetic 5/50 oil every 4k

Cheers
Marco
