Smoke from pushrod holes

[candyapple66]

Hi all-
I fired up my engine '200ci' after the rebuild and I used break in oil ran the cam in for 20 min then idled engine for about 20 and drained the oil. Today two days after with fresh 10w-30 high zinc oil i let the engine heat up then removed the valve cover to look at the valve rocker movement and noticed some light smoke coming out of a few (2) of the rear pushrod holes. Why would this smoke be coming out of the lifter/pushrod holes? Should I retorque the head to spec? Blown head gasket? Lol

Oil pressure is good according to in car gauge and i did install new oil pump during rebuild...

Don't think a bit of blowby even on a new rebuild is really unusual. Give the rings a bit to seat- butdon't expect a perfect ring seal

Best way to break in a new build, is to drive it like you stole it.

I drove around my neighborhood today but my harmonic balancer seems to wobble and engine shakes a lil but im not sure if i need a new one. I have rpms set at about 590-600 while in drive on transmission. I guess thats considered high but engine ran smoother at that rpm.
