Really odd one this, that has blighted my motoring years so far. Before going any further I've never had an engine failure or any that really exhibited signs of anything sinister.
I have had an issue with all my petrol cars where I obsess over how they sound. Every cold start, every time at traffic lights, every time I give them bootfull... I always hear something that worries me then I obsess over that for ages and ages and ages. This is not something that affects me with the diesel cars I've had. Perhaps because they're already much rougher than petrols & their nature hides any other unusual noises.
My father is the same, although I don't think he obsessed over it to the extent I do. Both he and I have been able to hear difference that others can't, which he attributes to us both being musicians with perfect pitch - I don't know whether that's an influencing factor or not.
Anyone else like this? How do you get over it and enjoy the car?
(And yes, I do realise the responses I'm likely to get as I primarily am known for Roverfetishism!)
