White smoke coming out of the PCV valve and valves making noise after crankshaft replacement

This vehicle had engine knock and I dropped the engine and removed the oil sump. I saw that the crankshaft had been affected, so I replaced the crankshaft and the oil pump without disassembling the whole engine. So after replacement of the crankshaft, I lift the engine to the engine compartment and when I crank, I heard some kind of noise showing that oil has not reach the valve, so I let to idle for four hours and it didn't stopped only to see that white-smoke was coming out of the tailpipe, then I unplug the hose on the PCV to intake manifold, and I noticed the smoke was from there. I loosened the valve-cover and cranked it again. While idling, I saw the smoke was from the hole into which pushrod was incorporated, I applied oil directly to see if it can stop but no way, at this point what would I do to over this valve noise and smoke? Your suggestions will be appreciated. Thanks
