After 4 short flights,the silencer face seems to have melted,and the resulting uneaven face on the silencer has pitted the face of the engine.The silencer bolts were captive,the bolts were wired,and a gasket was fitted.The silencer is a Pitts type and although not very heavy has vibrated sufficiently to cause friction welding to take place.The silencer was unsupported,it will be next time.Advice please,do I use a gasket?,I cannot get both mating faces flat,as there is not enough metal on the engine,therefore I need a filler of some type,ie plastic metal,any ideas?
