Has anyone else had this problem? During my annual which has taken two months, I installed new engine mount bushings and they all show signs of cracking. I have not run the engine yet. The IA did his final inspection today and noticed the cracks and asked if I had over torqued the bolts and I told him I did not. Is this just bad rubber or has someone else had the same problem. The IA told me to go ahead and fly it that way and keep an eye on them. The ones I took off had only 100 hrs on them and they were all cracked.
