Bobcat 743B [v1702 Kubota] - new engine "blow-by" question

[xMarkFitzx]

Hello All, Recently swapped out an aging v1702 for a fully rebuilt v1702. When I first got in installed and fired up, I noticed some (very faint) white smoke exiting the vent hose when the throttle was set to the absolute lowest position. Once I got it revved up to "high idle" or 1/2 to 3/4 power, it no longer could visibly perceive the white smoke. Later when throttling down to absolute lowest position, I noticed a little bit of the white smoke again. No oil at all coming out from the vent. I placed a white terry cloth underneath it and throttled up to various positions to see if any residue would appear on the cloth and none did. Should I be concerned? Could it simply be assembly lube burning off? I'm also willing to chalk up my newbie status and are new to small diesel engines.

I'd like to think it's just the engine bedding its self in too, it will need some time to seat the rings. Get it working, load it down, get some hours up and see how it performs afterwards.
Keep an eye on the water and oil levels to ensure that nothing is wrong.
