Nissan Patrol 2006: Rebuilt engine blows smoke

...

AFTER a complete engine overhaul because of a severely cooked engine in my Nissan Patrol that included a new cylinder head, bearings, pistons and turbocharger, the engine is now occasionally blowing smoke out of the exhaust. But the problem stops if I disconnect the breather hose. Do you have any ideas that could help?

Did they hone the bores in the rebuild? If they didn't, or even if they did, I would be suspicious that the rings are not properly seated on the bores and the smoke is blow-by. The problem could also be because you didn't run it in properly after the rebuild and the bores have glazed.
