It's condition inspection time again and it looks to be not so good this year. Over the last year I have flown just over 200 hours and in that time I have managed to install a rub mark on my engine mount. I found that the left exhaust pipe has been rubbing the engine mount where it exits the engine cowl and doing quite a bit of damage. The rub mark mics out at 0.029" deep. I am sure this is a grounding measurement, or at least it's grounded until someone can give me guidance on what is acceptable. I am running a Lycoming O-320-D2J 160hp engine with the vetterman exhaust. Does any one know what the wear tolerance is or where to find it ? Can this be repaired and by who ? or does it mean I'm buying a new engine mount ? Thanks in advance
