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.

did you do the valve stem seals, and valve guides too? new pcv valvle?

Yes, checked the valve seals and guides. I also replaced the PVC. Like I said it's not smoking much, only after the engine is warmed up. Maybe I'm just freaking out over nothing. Am I?

Thanks

if you used the good rings, it may take a little time for them to seat in. Use real low vis. cheep oil for about 500 miles, and then change to the good stuff. I usualy run them up to 50 in 3rd gear and then let it back off to 30 and do this a few times right at first. After that , just keep running it at different speeds for a while, it should be ok.

Did you bore it out?

Thanks for the advice Dave, I'll do that.

I haven't had time to look for the Lost Dutchman's mine, we have over 200 of our own to dig up nuggets on.
