Hi all. I have a 63000 mile 2004 2.5XS auto. One morning a few months ago, on a morning start, there was a *loud* tapping when I started the car. I shut off straight away. No oil under the car. Oil level was fine. On the next start, it was softer, and after about 30s idling it went away. I took the car to a local auto shop and they said it might be piston slap, but they test drove it and said it's fine. They did an oil change. However, since then it has done this ticking/tapping every time I start the car in the morning. The noise goes away entirely after about 30s and the car seems to drive normally. It does *not* do it on subsequent starts during the day, only after standing overnight.
Some observations:
-I understand high mileage boxers can have piston slap, but my engine is still 'young'.
-It never did it before that one morning.
-It *seems* to be louder on the left (from the front, facing the car).
Can anyone recommend a diagnosis method? Thank you for reading.
