So my rebuilt 2.7 now smokes like a chimney out the tail pipe (blows smoke rings, too). I have maybe 600mi on it and it didnt always smoke, just on this last long jaunt did it start. So, I noticed the oil level was low...I could have sworn it was full before I left on my last 300mi trip. When I pulled the cap off of the oil tank to check the level (while the engine is running) smoke came out of the filler. This would seem to signal to me that there is much blow back...I am hoping that it is because the rings have not seated, but wanted to know what you all think.

Overfilling a six-cylinder with oil can result in tons of smoke out the tailpipe. Every autoX school we get one new owner who doesn't realize you have to have the engine running when you check the oil level and overfills the heck out of it. The result is masses of smoke once the engine warms up and the car is tossed around. Always freaks the new owner out... (IMG:style_emoticons/default/wink.gif)
Dunno if this has any bearing on your situation, but... --DD |

When I checked my oil yesterday it was only wetting the very tip of the dip stick (IMG:style_emoticons/default/dry.gif) I definitely need to do some real diagnostics... |
