Greetings!
     I have a 1989 mazda pickup B-2200 it is an extended cab with a 4 cylinder engine an a automatic transmission. It has been serviced since new and now has 135000 miles on it.I know I have a small oil leak and My valve seals are worn. It smokes in the morning. My question is: Is there any way transmission fluid can get to my combustion chambers. ahy valve or any vacuume line or anything that would allow transmission to be leaking anywhere other than externally.Totally baffled
                   Thanks
