Front main seal leaking coolant... I think
Was under the truck for a couple hours the other day in pursuit of my coolant leak....spent most of that time wiping the bottom side of the oil pan and as much as I could reach up the sides.
The pics are from about an hours worth of driving earlier today. I see the general area where the Dexcool (I will replace with Peak when the work gets done) is running onto the oil pan, but not 100% sure I am calling it a front seal leak?
A few pics... Feel my pain? Not sure if any of them are showing anything that would give a definite answer on what's leaking but appreciate you looking. No chance a head gasket could be leaking from the front drivers side corner of the engine....that's where I am guessing the cooling is running down from.
I think the third pic shows the coolant running back towards the first exhaust manifold bolt.
Input much appreciated.

While coolant can leak from the heads, it can also leak around the front cover gasket and the water pump gasket.. See Oil Pump Gear Kit W/Gaskets - Land Rover kits from Atlantic British, I am not suggesting you have to change oil pump, but this is a pix of cover gasket and WP gasket.

It very well could be the FRONT COVER. can you get a coolant pressure test done... that is how I found my front cover leak... noticed that I was loosing pressure after 10 minutes. crawled under the truck to find the drivers side side of the front cover leaking..
I would strongly recommend doing a pressure test. before you start buying and replacing parts.

Will agree they can leak coolant, mine did and was wobbling. Inside, the wobble and tight spacing = eat aluminum. Can leak at nose or $2 gasket, or the cover gasket. Biggest PITA is the fan clutch bolt, put long handle wrench on, pull up hard on serpantine belt, and slap wrench with a hammer toward the left when facing the engine.

Quick update
No person should see what I think I saw today. Son of a.....
I cleaned the heck out of the front end, down to the oil pan. I could not get the pressure tester today, but figured I would go under the truck with it running and have a look.
Obvious small "pulsing" stream of very clean coolant a couple mils wide running down from the drivers side forward head area.
The yellow line represents where the coolant was running and the second pic shows the actual run itself.
I assume I will be told to get the pressure tester and remove the fan and anything else to see for sure?
Is there a chance...any chance that it is not the head gasket?. Any other issues with leaks above timing chain cover? In other words, when I get the tester, what should I be keeping my eye on, besides the front of that head?
All you senior guys on here are awesome. Thanks in advance. Brett

if it is leaking along the line you have drawn it apears to be the intake/valley gasket.
But do not rule out the timing cover gasket, when mine let go it was shooting water on to the intake also. I had to remove a few things like the alt. and ac compressor to find it. It was a pin hole under the ac compressor that was spraying up on the bottom of the compressor and leaking back on the intake. Best to set time aside and preasure test the system wiggling and tighten every connection on your way.

I had the same leak when I first got the truck, and it turned out to be the small coolant tube in that area that goes to/from the throttle body heater. Look at the cooling diagram of RAVE, and it is the two in/out hoses on the bottom of where the plastic intake hose meets the intake. There was a leak there, and a leak in the hose on top of the engine where the outbound flow to the throttle body heater goes. The return goes back to the tank.
