You never say what the symptom is. If you cannot accurately articulate the symptom then it is unlikely that you will get a good response.
My best interpretation is you are losing coolant and cannot figure out why.
Head gasket issue does not mean new engine
Like I said, I’m taking it to a different Land Rover specialist to run some more tests to see if it is a leak or something internal with the engine.
From what I understand (have been told), if it is a head gasket issue, not many shops will attempt to repair it and the better option would be a replacement. I’m not at that point yet where I’m making that decision - still trying to gather more facts but started this thread to start mentally preparing myself for what may be necessary if I’m not willing to depart with my LR4 (which I’ve pretty much decided I’m not willing to depart with it).
I can’t articulate much more than what I have indicated. My coolant reservoir tank has gone pretty much empty after around 5k miles over the past two years (after doing all the recommended coolant system replacement stuff two years ago), and that frequency of losing coolant seems to be increasing.
I haven’t noticed any change in how the engine runs. But I did notice visible white smoke (not super thick but still visible) coming out of the exhaust after starting the engine the past couple of days. But after I drove it a few miles, the smoke was gone.
I also noticed the engine being fairly warm two hours after I drove it the other day. Not sure if that is normal or if it should be cooling down faster after engine shut off. And I noticed a wheezing noise for a minute or so from somewhere near the engine / coolant tank after I shut off the engine - not sure if that was the water pump doing its thing before it shut down. I’m clearly not mechanically inclined to diagnose if that was a normal sound or not. But another shop that supposedly diagnosed the coolant issue recently indicated they could hear the water pump was going bad and they recommended a replacement. I don’t want to spend the money to do that right now until I confirm it’s not the engine itself burning coolant. I would be thrilled if that is actually the issue and the original water pump replacement I had done two years ago simply went bad.
That’s all I know right now. Hopefully will find out more after the next pressure test (and combustion test, if the pressure test doesn’t identify the source of the leak).
