Ok, maybe my good deal wasnt' so good after all. The beast; 91 Blazer S-10, 2 door 4.3 (4x4). It runs good, but after running a tank of gas thru it, I noticed it had blue smoke this morning after I started it up the first time. It's been sitting for a week. It only puffs blue after I rev it up and let off on the gas. So, is that bad intake or exhaust valves? jb
