My car starts smoking (not much) when idling, so when i take off a puff of smoke comes out of the tailpipe. I also have an exhaust leak where the manifold and head are connected. At the leak there is carbon deposits around the area but also is oily. I haven't taken off my manifold for the fear of breaking another stud. But last time I took it off couple months the valves seem to look normal. Now for another question. My car tends to drop oil pressure on the expressway. When entering the expressway the guage is around 5/8 up but after driving a bit on the expressway doing 70 at 3k rpm it goes down to 4/8. Im very paranoid of the pressure because i do not want to rebuild my engine for the same cause all over again. Is it normal for the pressure to drop a bit because the oil is getting hotter? Oil i have on is 10w-40
