Hi Guys, I acquired an excellent 2.0 DOHC Sportage as part of a debt repayment. I say excellent . . Its a year 2000 4x4 manual transmission and the bodywork is spotless and so is the interior. I was told by the owner that it had been off the road for 6 months as it had starting problems. He said he'd spend £300 on trying to sort it out but all to no avail. Its got 63k on the clock. It will not start on the key but it does start with a tow. It seems to run ok but after 10 minutes its overheating. I did a compression test on it and it went 48, 38, 52 and 62 psi so I assumed the head gasket had gone. On dismantling I found that the thermostat was missing, the spark plugs are a great colour with no fouling. It seems the head had already been into the shop as it was spotlessly clean and came away from the block easily. The valves and oil seals have also been done. Its got a brand new cam belt on it and everything lines up. I swapped the head gasket as I had it off, reassembled and its still the same. I asked the previous owner and he said he was using it when it overheated. Diagnosed as head gasket he had the head skimmed and the valves done. He reassembled and its as it is now. Any ideas ? Why would all the cylinders have relatively low compression ? When running it sounds ok - ticking over. Any help will be appreciated.
