Some background. I have had the car for about 18 months. I have had engine vibrations for the last 6 or so after the car set for about 4 months. Recently I went to replace the manifold to downpipe gasket due to an exhaust leak and a stud broke. I figured that since the stud needed to be fixed I would go ahead and put a gasket set on the top end. So I did the head gasket, valve stem seals, valve cover gasket and whatnot. Now here is the deal. After I did that the vibrations smoothed out a bit until last week when they came back full force. I now have smoke coming from the breather, the thick white type and I have the following compression
150 - 60 - 150 - 150
So any ideas? I'm going to take it to get a leakdown done on it since I don't have the tools for it. TIA

Save your money, don't do a leakdown test. Yank the head and and look at the #2 Cylinder. Its either a piston, bore or something obvious with the head.
