I sorta suspect that "Silencer", is the "Muffler" or exhaust?
If this is the case, and it seems to be more than just condensation,
It may be a Blown Head Gasket, or a problem with the Heads.
As far as the coil, is this the 1st time you have touched it. Coils do get pretty warm, just with normal driving.
I truly suspect a "Head Issue" and every attempt to rid it's symptoms, maybe like running rough (water on the spark plugs, compression) and adjusting the carburetor, are Fruitless
You need to have the cooling system pressure tested. This would be the starting point.
