Knocking on startup ?
I have a 1998 C280 Sport, 52K with the Starmark and when it's started after sitting over night it knocks for about 1 to 2 seconds(like a bearing is bad or from lack of oil). I bought the car with 50K on it and just noticed the knocking the last 2 or three days. And ideas ?

You might have a bad rod, that tinking sound on Jap car after shut down is the exhaust, I don't know what but it have to do with the heat shield being used. Does you car still have a warranty ?

knocking on start up
Have you shecked the oil filter. Some oil filters do not have the stop valve, this would allow the oil in the gallery to flow back into the sump when engine is turned off.
