Hi, Not long ago we bought this Honda Accord 2003 CM1, 250k kilometers driven. As usual all seemed fine after buying car until some 3 weeks later I noticed engine noise similar to diesel, only audible in low revs. Seems to be quiet or absent with hot engine and high rpms. Oil is fresh, but have no idea what oil previous owner put there. Also drive belt needs replacement. Some information I found in the net is that it could be some oil pressure related problems, some say sound is gone for a while after cleaning VTEC solenoid. For me its more like rod or crankshaft bearings on the way out. Any help and tips appreciated! Here´s video, what you think?
