Hello, I've been a somewhat proud owner of an Accord 2004 with the 2.2L i-CTDI engine. As you would expect out of a Honda diesel, it runs and sounds more akin to a petrol than the usual diesel engine and my engine is no exception. My concern is that along with the usual diesel rumble, it sounds like there's a hint of scratching noise from the timing chain cover. The sound isn't consistent, as it goes up and down in volume and almost sounds like chirping. To me the obvious cause seems like the timing chain, but I wouldn't describe the sound as a rattle. The noise is basically always there, regardless of if the engine is cold or hot and even in a cold start, it's only marginally noisier than starting hot. A culprit could be the 5W40 Castrol oil that the shop decided to put in (I asked for 0W30, but oh well).
