I've owned my 90 for the past 170K miles. It's got close to 200K and the engine hasn't been opened yet. She's been a daily driver her whole life so maybe that's why she's faired well so far, who knows. My conundrum is I'm planning to send her to CO and meet her there, primarily for the Land Rover Rally in Ouray in July. She's not overheating but if the ambient temps are in the high 90's she can get into the low 200's at highway speeds. Her coolant res will occasionally need some topping up, so I'm assuming she's probably losing some coolant through the head gasket somewhere. Part of me feels things will be okay, but another part of me feels like maybe I should put her down and do the HGs before the trip. At 200K though, she's probably also due for some attention on the bottom end as well. Is it ill-advised at this stage only addressing the top end? If so, I'm a bit concerned I may not have time to address everything the right way the first time.
