Hello all,
I purchased a 2013 LR4 a couple months ago with ~150,000 (incredibly good condition/looks almost new inside and out), but have been adding a pint of coolant every couple of weeks. I thought perhaps that it was a head gasket since I also have intermittent (very intermittent/historic) misfires on a couple cylinders.
I've replaced spark plugs and ignition coils (big improvement on misfires, but still present occasionally). I've now been running some Liqui Moly LM2030 Fuel System Cleaner and again, noticing improvement (perhaps I just need to replace the injectors too, and I need to stop being cheap)?
Last night I ran a hydrocarbon block test on the expansion tank, tried several times, fluid remained blue every time, so no exhaust gasses detected. However while I was in there wearing a headlamp, it was much easier to see things being out of direct sunlight, and I think I see dried up coolant residue on the rear crossover pipe. At least it looks like the rear crossover pipe to me. Thoughts?
