Re: Engine smoking...and I don't know why
Without any test results, we're shooting in the dark but here's my wild guess at this early stage.
Do you have one or three piece oil rings? The one piece ones are as useful as fly screens on a submarine.
If you have the 3 piece ones, the scrapers have an up and a down side. Install them up side down and they won't work so well yet I've never seen this mentioned with any of the sets I have installed over the years.
Is there any chance something has found its way into a cylinder and scored the bore?
