4.0 leak

[dragford68]

I have a 98 Ranger 4.0. I have a major coolant leak that comes out from behind the AC compressor/PS pump. I replaced the lower intake thinking that was the problem, and when I took it off, the end rail sealant in that front corner looked suspect. Got it all back together, runs good no leaks. That was three days ago, today it is leaking again. Heavily. Very hot here today and when I got home, I could hear it hissing so I went out and looked and it is coming from lower down like near the bracket for the PS pump. If I fill the radiator, it starts leaking right away. I will be taking that pump off so I can see, but what is behind there? Is the another freeze plug? Or something else?

Looks like a small hole where the timing chain cover bolts to the block. Gonna pull the front cover and see what the hole is.

Does antifreeze leak if the front timing cover gasket is bad?
