Bad coolant leak need help fast!

[73rvhauler]

So my truck had a coolant leak it looked like it was the oil cooler. So pulled oil cooler and replaced seals and gaskets. 50 mile test drive its still spewing coolant. So look deeper and took off ac and powerstearing pump and lots of build up at freeze plug. Could my freeze plug have failed? And can I fix with motor in truck or what else could it be? Any help right now would be greatly appreciated!

Could be many things, need to pressurize system and watch. Mine was the timing cover, but like said before could be water pump could be egr cooler or bypass hose if deleted. Pressurize and watch is the best option I can tell ya.

Well the water pump is new I thought that was the leak but it's not. If its the timing what all is entailed it that is it just a gasket or do I need a new cover?

most time just the gasket. there are water ports towards the top of the cover and there is a rubber donut gasket where the intake connects to the cover where water could be leaking. Its a big job to tear it all down. the turbo has to come off and intake needs to be loosened so you can pull it up to get the timing cover off and the new gasket place. Plus your radiator fan and all will have to come out.
