Actually, There is no trace of oil in the coolant reservoir and oil actually drips from the exhaust while the engine idles. There is a steady idle (no missing at all) but there is an oily haze from the exhaust if you increase the revs. The smell to me is not like regular burning engine oil but smells more like transmission fluid. However I do not know what Mobil 1 smells like when it burns and the engine has Mobil 1 at the moment. I had a mechanic look at it last Saturday and suggested there wasn't any evidence of a gasket leak so I think I will do a compression test before trying anything else. If you have any second thoughts after reading this, please advise.
