To make a long story relatively short, I rebuilt my 3.0 last year , and added an old BAE turbo kit to it. Had lots of compression loss; turns out I stupidly used the wrong oil rings...I put in later 3.0 oil rings, and should have used the early. I pulled the engine back apart after realizing something wasn't right, and refitted it with the correct rings, and yes, this time I checked the side clearances.

So, now, I have the car drivable again, have maybe 100 miles on it, plus 1/2 hour initial run at 2500 RPM. It is using a bit of oil, as in burning. The tailpipe is black, some of it carbon from tweaking my mixture to get the AFR OK, but it's oily, and I do notice some additional blue smoke also. I am going to check the oil tank vent, which I feed back to the air filter to make sure I'm not puking oil back into the air inlet.

However, I am concerned that I'm leaking past the rings. How long does it take to seat the rings? I figure I'll give it a bit more run time before I look for the razor to drag across my wrist.
