Are center risor manifolds, for the Chev 350, prone to cracking exteriorly between the two center exhaust port flanges?
I have a friend who has both mani's cracked in the same place. They are just dripping water but they are definitely cracked. The mani's are original raw water cooled units but have never been in salt. They are 1990.
He's trying to determine if he had a winterization drain down problem or if this is just the nature of the beast. They are not cracked internally as there is no evidence of water on the plugs.
