Sorry I hadn't gotten back until now. I had an oil leak around the camshaft position sensor. Just got another one in today and the oil leak has stopped. The white smoke has also disappeared. After driving it for about 100 miles, it stopped.
Thanks to all who helped me through this process. It has been very satisifying to do this cylinder head gasket. I have gained confidence to tackle other repairs. I couldn't have done it without this forum.
