Loud clatter at startup (GT3)
Some mornings when I fire up the GT3, the engine makes a really loud metallic clatter noise for a few seconds until the oil pressure comes up. Then it smoothes out normally. Is it a hydraulic valve lifter run dry overnight or something? Anyway, I believe it's nothing to worry about (the service manager at my dealer agrees) but I was wondering if anybody here could explain it properly?
Also, I'm trying to find a pattern as to when it happens and when not. My one theory (yet to be scientifically tested) is that I think it happens if I rev the engine a bit before turning it off the day before. I think that if I let the car idle for a while before turning it off, the clatter does not happen the next day. Does this sound like crap? Any ideas? TIA.
