well i could not tell you what caused it,but the guy i bought it from did not even tell me about it. and it has been fixed what looks to be good. just pro need to find exactly where its leaking and slap on some jb. there were 3 booged studs but i took time and fixed them. i also have the crank clip and tranny clip. but i have not found the cable hold down or the hold down for the clutch lever.. don russell
