The spring on the left front of the exhaust (just below the #2 cylinder) has been rubbing the cowling air duct. The rubbing has gone through the heat shield and is now working on the fiberglass. The air duct is dimpled to make room for the spring; but, in my case, it looks like it could use another 1/8? to 3/16? of space to keep the spring and air duct from rubbing together. This is the original exhaust system on the 912ULS. This condition was found during the 200 hour engine maintenance (replace spark plugs, etc.).
I am thinking of cutting an oblong hole around the spring?s mark on the air duct and fiber glassing in a bubble to make more room for the spring.
Any suggestions?
