Hey guys
I need some help I realise this is more of a general engine question. I have a 1976 Firebird formula with a 1971 455. It has been rebuilt everything has been replace with new on the inside. Now I know that when you do your cam break in you need to run it 20 to 30 minutes no load but I had multiple issues. My alternator was sending voltage to the casing then so I had to replace it (it was brand new). For some reason the rear main let go the second time I ran it (f me) and its leaking bad. I was not able to run it more then 7 to 10 minutes the second time and the first time it ran maybe 3 to 5 I had nasty sparks on the alternator. Did I do any damage to my engine. I cant run it right now do to rear main splashing oil on headers and it starting a fire.
Thanks
