I got an W124 from 1991 model 300E-24
It got the M104.980 Engine 3.0 Liter with 24 Valves.
I got this ratling sound at the top of the engine
And the sound can sometimes go from cyl. 6 to cyl. 1 or stay in the midle of the engine, but always from the top of the engine.
The strange thing...
I am getting ratling noise underneath water pump and power steering reservoir when i put the gear in "D"....on moving gear to "P" sound vanishes.
Is this the problem with the power steering pump or belt needs to be adjusted????
