Sods law, after recently posting regarding keeping car in good nick mechanically wise, something crops up. Diesel Citroen Xsara, 1.9 Non Turbo, DX Engine, 55'000 ,miles, oil / filter changed 280 miles ago '98 (R Reg). When starting, engine is fine but you hear what I can only describe as a 'metallic' sound. Not dissimilar I would say to two spoons being 'knocked' together. Missus says sounds like 'birds chirping'. It will happen about 4 times a minute, no sequence etc and never stops. Happens even when hot. (Engine had two hour drive and still was same). Everything else appers to be ok, but it is definatly a new problem. It is usually only noticeable when idle, but I'm sure I heard it a few times on the motorway yesterday. (65-70mph). Checked oil levels etc and they don't move (never have!). Please help, I'm somewhat anxious as, as previously posted really can't afford huge repair bills.
Many Thanks
Old Fa*t
