Just rebuilt my 87 sam with the 1.3. Replaced pistons, rings, bearings, ect, ect. When I first started up it ran real good. In fact I couldn't believe how quiet it was. But after running it for awhile, I saw blue smoke coming from the exhaust. Not a lot, but some. That was the reason I rebuilt it in the first place. My question is, do the rings need some time to seat? If so how long, what speed should I run it?
At my work when we rebuild diesel engines, we run them at top speed for a couple of hours to break them in. But thats the govt for ya.
Thanks for the help.
