My rebuilt B20B is going to get a leakdown test next week. There is about 1000 miles on the engine.

Think that's enough break in miles to take the test? What leakdown percentage #'s should I be getting on an engine with 1000 miles? Deves rings were used, I'm told they seat fairly quickly.

I'm predicting some wacky #'s unfortunately. The B20 F head was rebuilt at same time as rest of engine, and I've been getting a big cloud of oil smoke at startup ever since. Worn valve guides seems to be the consensus. I'll post results next week.
