Static coolant leak OHV

[KaHOnas]

I replaced my heater valve a few weeks ago but that resulted in a new leak. The valve was old, cracked and seeping coolant and probably had been for some time.

After replacing it, I figure that since the cooling system can properly pressurize, a new weak point was discovered. The leak was happening from the front right side of the engine around the water pump with the engine off. I assumed it was the water pump so I replaced that along with the thermostat and the upper and lower radiator hoses.

When filling the system after replacing the pump, it began dripping in the same spot. Now I'm wondering what it could be. Assuming it's behind the timing cover, I once again collected parts and gaskets but I don't want to dig any further into this engine without a better idea of the possibilities.

Thanks all.

The timing covers are pot metal or aluminum, and are famous for corroding. See how much a new timing cover costs. Sometimes you can get by with a new gasket and some rtv if you find the cover has eaten away a little bit and has some rough spots.

If it's leaking BEHIND the timing cover, it should be leaking into the oil. Take a good look because the lower intake manifold gasket is bad for leaking too.

I did check the oil but haven't noticed any change in color or consistency. I have a video of the leak but it's not very clear.

That's good. External leaks are usually easier to find.
