Looking forward to this one! definitely needs a good cleaning of the top end before firing up. Also probably a good idea to start with fresh oil (high ZDDP/zinc) and filter, might be a lot of water in the oil. Possibly prime the oil system before firing up by driving the oil pump through the distributor hole. The V6s have a hex drive for the oil pump, a socket should fit with a long extension I think? Just don't drop the socket in there
