Message	Hi, When I received my replacement Z1 water heater hard pipes they did not have any gaskets included. These are what their NA heater pipes look like with the throttle body feed pipes welded up. The factory service manual page LC-10 (see this TT.net page) just shows that the connection between the heater core hard pipes and the block/return pipe as a sealing point. The hard pipes are chamfered on the inside and I did find the remnants of a rubber ring from the old pipes that fit into this chamfer on my 1995 NA. Do you just use small amount of RTV on the flat mating services to seal in the coolant?
