Our 2000 Discovery II started overheating last year. I pressure pumped all antifreeze lines, nada. Replaced the thermostat. Drove fine for about 3 weeks the overheated. I just parked it. About 4 or 5 months later my son started it up and let it run...1/2 hr later, no overheating. After a few times of doing this, we took it up the mountain to get some boulders for me to build a fountain. Ran fine, on the way home it went red again. WTH? My other son took it to the dump, was fine, then BAM..Wouldn't run right. I went and got it later, was running HORRID, no compression on several cylinders, drove it home and parked it. Only time I ever blew a head gasket, I was on the freeway and saw a white puff of smoke, lost all compression, it rained antifreeze and wouldn’t start again, till I fixed it. This still starts, would run if I allowed it to, crappy…Compression test on left side was between 90-100. Left front, (#1?) was 42. No. 3 had 0 compression. This was done by taking the plug out, putting the gauge in and cranking 3-5 times. My older son drove up and said all the plugs had to be out to test it. Is that true? I don’t have a lot of money, but need it running. Should I replace the head gasket and have the heads machined? How to I tell if the valves, rings, and pistons are ok?
