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.

You don't want to know... really..... Group: Members Posts: 2,515 Joined: 12-September 04 From: Newport Beach, California Member No.: 2,743 |
Well... As far as thr rings being broken in. Bout 80% of the ring break in happens in the first 20 minutes of the engine under load. In essence. Your rings are either broken in NOW. Cause if theyre not.....
Ya have to re-hone and install new rings. IF that is your problem. Could also be guides. Could also be you are venting oil back into your intake tract if you have a mechanism to do so in your engine configuration. (Like PCV or some crank case to intake manifold hose or valve) Check that first. if no leaky......... YOU NEED TO DO A LEAK DOWN TEST and figure out if it's internal. Thats my thinking anyway... Problem is... You know all that stuff. What do you think is the problem.......?????? Clayton |
