Oil/ similar substance in Coolant
#11
Pulled the fan to get better access to the leak area. Here are more pictures.
I actually have a water pump sitting around, but I bought it before the Flowkooler was available so I went ahead and ordered a flowcooler since regardless of the issue I expect I’ll be doing a water pump.
I’ve seen a few folks mention the “weep hole” on the water pump. Does that look to be the leak location based on these pictures? The bulk of the coolant build up is around the front cover on the drivers side behind the water pump.
Oil in the coolant is only possible via a headgasket leak, or an oil cooler leak. Is that right? So regardless of whether or not my water pump is leaking, there’s another issue as well.

Regarding oil in coolant, recall there is slight vacuum produced as the engine cools down and the coolant contracts. If there is any oil around the leak, then a little oil could be sucked in to the cooling system. It's good you paid attention to the little clues these engines give us. Some folks do not tighten the coolant cap, so no pressure builds up, and no vacuum either.
If you are worried about head gaskets, first do a compression test.

Maybe it was assembled previously with no silicone and eventually that seal broke.

Which is why it’s been giving me a headache. Would be much simpler if it just had a milkshake under the oil cap.

I bought the truck from my friend who’s the lead tech at our local Land Rover independent shop.
He’s thinking the timing cover gasket is the cause of the leak based on the pictures and description of what’s going on.
So looks like the truck will be down for a few weeks while I wait for an appointment slot to open up. If he felt it was just the water pump then I’d knock it out this weekend, but alas. I very much trust his input.
The truck is my daily. My wife and I can carpool easily but it’s a bit of a strain. I’ve been driving it this way for a while, but I can’t in good conscience continue driving it knowing the extent of the issue.
This Disco has given me about 15k trouble free miles over the past two years. I’ve spent less on it than I have on my wife’s Acura RDX with less mileage in the same time frame. Can’t really complain…

Its a slow leak. But the oil in the coolant is getting worse every time it runs. I’d rather not have a failure with my daughter in her car seat so I decided to leave it at home and carpool with my wife until I can get it sorted.
Just hate the consensus seems to being timing cover since that’s obviously a biggie compared to a water pump.
