Fluid on intake manifold

I have a 1980 cj5 with the 304. There is a substantial amount of fluid that is pooling up on the front of the intake manifold. At first I thought it might be fuel but there is no fuel smell. I don’t think it is oil, as its pretty “thin”. This has me thinking its water. There is enough that it fills up all of the crevices on the front of the manifold. The jeep does sit for a few weeks at a time at a weekend place so I can’t check on it daily. Any your thoughts on what it is and where its coming from?

I tried search and couldn't find anything. Also, I realize that pictures would help but the jeep is 3 hours away and I didn't think to take them.

Most likely it's coolant leaking from the gasket at the t-stat housing, or one of the hose connections at the same location. It's pretty common.

Smell it! Coolant has a very distinct smell, unless you don't have any antifreeze in the mix. It should also have a green tint.

Unless he's using the orange stuff.

Can we get a pic? I know you said you don't think it is oil but a really common leak on the intake is oil coming up through the intake bolts. Is there a bolt where the pooling is?

I've seen this caused by a faulty intake gasket as well. Need to identify fluid first though....

This is slightly off topic but I kept getting a small amount of oil in one of the pockets on the passenger side of the intake. Finally figured it to be caused by me driving up onto a bank and getting the jeep on a steep sideways angle. Which is letting oil that is on top of the head seep through the "bad" valve cover gasket and onto the intake. Which in this case its got to be the thermostat housing leaking or the intake gasket leaking and seeping through one of the front bolt holes.

Pretty sure it's water. Looks to be coming from the top radiator hose

I have just recently learned that you shouldnt have the spark plug wires zip tied like that in your pic. I rekon they need at least 1/2" space between them.

I think I fixed it. Now it just won't start. New optima battery but acts like its dead. Get some power as I can cross the starter solenoid and get spark. Plus oil gage works when key is one but that's about it.
