Hi Amie. Thanks for contacting us today. A rattling noise like you have described is often caused by a loose bracket, belt or pulley. On the driver side, a power steering pulley could be the source of this noise, while a loose radiator fan shroud or other bracket are other possible sources. The best way to diagnose any noise is to have a professional mechanic test drive the vehicle with you, and complete a car is making a noise inspection; in an attempt to replicate the sound. This allows them to isolate the source of the noise and recommend the right repairs.

Hi, I have an M156 engine that me and my friend took apart replaced the faulty cylinder headbolts and other gaskets and now that we've put everything back together the oil is mixing with the [coolant](/topics-coolant-mercedes/) and producing chocolate milkshake kind of fluid. When we pour approximately 1 liter or more of water into the coolant holder thingy (forgot the name) it pours out the oil pan in the bottom after 10 or 20 seconds. We've tried to narrow down the problem and found out that it is probably from the water pump entry. We disconnected the hose that goes into the thermostat and it still leaks but when we remove the water pump hose from the radiator it doesn't leak. We took out the water pump and it looks fine and also has a new gasket and when we pour water right into the water pump opening it comes right back out and doesn't go in, so it looks like a mystery to use but maybe someone more experienced can help us out.
