Hi Tasman,
I don't know what would cause coolant in both pipes at the same time but if you end up changing your intake gaskets, I would highly the FelPro Fel Pro 1247S3 from Survival Motorsports. The FelPro Printoseal gaskets failed after 3 months and so did the Cometic gaskets. The Felpro 1247S3 gaskets have a steel insert and I haven't lost a drop of
oil or coolant since installing them this summer. I also used the Motrocraft TA-31 RTV which I purchased from Rock Auto. It has a nice grey color so if you do have a little squeeze out, it matches the aluminum color. Much easier to use than the Right Stuff IMO.
Hope you get to the bottom of it soon.
