Lately my 84 240 DL has been sporadially refusing to start up right away. Instead, it make this bone chilling screeching sound like you would hear if you turned the key while the car was already running. After this happens I have to wait a minute or two and the car will then start right up. Sometimes it takes a few tries. I took it to my mechanic who looked at it a while and determined that the starter was bad but that from the looks of it he suspected that the fly wheel may be eating up the starter. he offered to put a starter in no charge and see what happens. if the problem continues it seems like i will have to do the fly wheel. Has anyone ever had this problem before. Is this the correct diagnosis? I understand that there is a lot of labor involved in a fly wheel job so I hope that this does not have to be done.
