OK so the shop rebuilt my engine and used the Nissan Fluid (999MP-1217HP) Liquid Gasket (supplied by me) and used it on everything including the coolant pipes. I informed them this is not recommended for coolant as stated on the container. They have said they will redo the coolant pipes. Now some peeps have said they use it on everything and others say don't use it on coolant. Z1 said don't while CZP said they do. Has anyone used this for coolant and did you have any issues? I'm guessing it should be redone as I don't want to 'want to have any issues in the future.
