Over the summer I had my engine re-built with a .30 bore and fully forged internals. I also had my vortech s-trim installed. When I got my car back it started smoking when i would crank it up. Sometimes a little and sometimes alot. I noticed that if i park on a downward slope, it seems to smoke worse. The previous engine did this also but my mechanic said that the rings probably didnt seat. I am trying to figure out what the problem is so I can get it taken car of. Surely the rings just didnt seat two times in a row. Any info would be greatly appreciated.
