Hi there again, I'm about to dump some more money into my old car again. 150.000 mi./ 13yr old. Before I do this I think I should be looking at the condition of the engine. What I know : uses very little oil, spark plugs always look great, runs good, feels good, new valves 40,000 mi. ago, good reputation for durability (mitsubishi motor 4g63), and I'm going to compression check it tomorrow. Any thoughts on what else I might want to look at or check into is very much appreciated. Sincerely, Greg
