W202 M112 Engine Tappet Rattle

[Tony240]

Hello All

My new to me C240 has a little tappet rattle when first starting from cold. Goes after 2 or 3 seconds of running and no noise at all when warm. I've had other cars that did this as the tappets tended to drain and it didn't seem to be a problem. The car had an oil change just before I bought it but I've no idea what oil was actually used. Car has done 88K miles with full MB service history up to 83K miles. So my question is, is it normal to have a bit of rattle on start up or might this be related to the oil that has been used.

Many thanks

187k and counting on my C240, generally is tappety on startup then goes. Car has oil changes every 3-4 month so not hugely fussed about it.

Thanks for the replies guys. I wasn't too worried but its my first mercedes so just wanted to be sure. Anything I should be looking out for on this car?
