Hey Sam,

Blue smoke means oil. USUALLY a head gasket will bring coolant smoke (white) with it. Often times but not always, it will also tend to run higher water temperatures. If the gasket is blown between the cylinder and an oil passage, the compression will leak into the crankcase and you'll see excess oil in the intake area. Not saying it's not the headgasket but look for those other signs. And do NOT take the engine apart until you know for sure it's a head gasket because you can't diagnose it then...you have to guess at that point. Have you looked at the spark plugs? Is one black and the rest tan or are all of them black? If only one plug is black, then we need to start looking at only that one cylinder...if they are all black, then it's probably oil coming in through the intake manifold. I am leaning toward what HondaDustr said but we still need to do some more looking before we know for sure. Let me know what the plugs look like.

If it is the oil/air separator, then it's not too bad a fix. The toughest part would be removing the intake manifold or loosening it and pulling it back to get to the part. The oil/air separator is the black tube where you put oil into your engine. There are three bolts that hold it on if I remember correctly and you have to remove those bolts and pull it out, put on new orings and put the three bolts back in. BUT, while you have the intake off, you will probably want to replace all the vacuum lines under the intake as they are probably old and brittle. So, you will need some vacuum lines, intake gasket and the oil/air separator o rings.
