Troubleshooting coolant vacuum fill failure
I could be wrong (I'm not an experienced JLR mechanic) but from what I'm hearing in this thread as well as from the JLR mechanic I talked to, the tests that can be done to diagnose a head gasket breach, a cracked cylinder head, and/or any similar engine damage are pretty darn accurate, but a... -

Troubleshooting coolant vacuum fill failure
@Land Rover Joe I think the loose lower radiator hose dumped coolant faster than the sensor could measure the temperature increase and so even though the engine was only on for about another 15 to 30 seconds after it went into limp mode, it was at operating temperature and then rose well above... -

Well folks, hate to say it but I found coolant in the oil pan. What a wild ride this has been, and a very sobering reminder that everyone makes mistakes. I’ve been wrenching on my vehicles for probably close to 20 years now. First ever engine I worked on was a 5VZFE in a 1998 Toyota T100. Had... -

Thanks @Land Rover Joe ! I work from home and we have another car so I have the luxury of time and space, it’s just whether I’ll want to take the time to do it, should evidence reflect positively on the engine’s well being after these next couple tests. I have a toddler who keeps my wife and I... -

Yup! In that first picture I’m oriented to what I’m seeing on the block — I see you have the oil cooler and lower half of the front coolant crossover pipe off. -

Troubleshooting coolant vacuum fill failure
Oh and FWIW re: the engine temps, I did notice that my coolant temp never got over 210 on the 30 minute drive I took after I did the system overhaul but before that second drive on the highway that caused these problems. So if 230 is “normal” then the overhaul did a great job at lowering the... -

@Land Rover Joe and @jlglr4 do either of you know the level of effort required to get at the head gaskets? -

Thanks, folks. Good news is I serviced the supercharger when I had it off the engine during the cooling system overhaul. I replaced the coupler and the oil and the gasket between the supercharger and the intake manifold. The oil was kinda gross but even the guy who made the video I was following... -

I’m not sure what you mean by that. Either there’s coolant in places that it shouldn’t be, or there isn’t. -

I decided against getting the new expansion tank. Talked to an experienced mechanic at my local indy JLR shop and he recommended that I do 2 things: 1. Drain the oil and see if coolant comes out with it 2. Pull the spark plugs and use a borescope to look for coolant in the combustion chamber of... -

@Land Rover Joe thanks for the detailed set of questions / comments. I'm the 3rd owner (first two being a father and a son) and the LR4 has 86k miles on it. Oil changed about every 8k miles (higher than I'd have liked) at a local indy JLR shop, and since I bought the vehicle in January of this... -

I think before I do any of that, I’m gonna throw a Hail Mary here and see if the expansion tank isn’t the problem. It’s never been replaced, and it’s not wildly unlikely that a 10 year old piece of plastic exposed to countless heat cycles + the potential heat and pressure stress from last week’s... -

Troubleshooting coolant vacuum fill failure
Today I got back under the car and connected the radiator hose properly but got another vacuum leak so I put in close to 8 liters of coolant and then hooked up the pressure tester, but this time I am struggling to generate even a few PSI of pressure. No external leaks that I can see either (and... -

Thanks for the kind words, @Land Rover Joe! From one internet stranger to another, I really do appreciate it. :) And I love LR Time! I haven’t seen this one, but it makes me feel better to know that even Christian makes mistakes. I’m taking some time away from the LR4 this weekend, but when I... -

$56,000 2016 LR4 Landmark - Pricing typo or rising market?!?
Probably hoping some financially secure buyer stumbles in and doesn't know or care. ;)
