An Obscure Rattle
W/ITH few exceptions, every modern W car is fitted with some sort of flexible engine mounting, which allows the engine to oscillate slightly In the frame when it is pulling hard, and absorbs the vibration before it can be transmitted to the car. With this arrangement, some freedom of movement must be allowed for tho exhaust pipe where it enters the silencer, and it is at this point that a very annoying rattle may develop.
In some cars the joint between exhaust pipe and silencer is made simply by slipping the pipe into a slightly larger pipe on the end of the silencer, and gripping the two together more or less firmly by "U” bolts. It is when too much clearance develops between these two pipes that a metallic rattle develops, which may be difficult to trace. If such a noise is tracked to this source, loosen the “U” bolts, slip a packing of thin tin between the two pipes, and tighten the whole together.
