I have a coolant leak on the rear passenger side of the engine. Truck is a 91 f150 with a 351 Windsor engine with EFI. The leak is steady (more than a drip, but not quite a stream of coolant.) It's dripping onto the top of the transmission bell housing on the passenger side.

I checked all visible hoses and gaskets that I could see. I've removed the manifold and valve cover to give me a better look. In retrospect, I wish I would've pressure tested the system. Curiosity always kills the cat.

Thanks for your help.
