1st, it was the cracked exhaust manifold, then it was a missing issue with the aftermarket EFI from running E85 fuel… changed back to gasoline and blew the head gasket from it missing and knocking…. no damage, but found the exhaust guide seals were leaking bad, burnt oil all over the tip of the guide and in the port.. this is on an engine with less than 5k miles on it… who did the headwork (not me)?????
