1.6l: SMOKING. Built bottom end, smoke out of oil dipstick/valve cover
So just got a built bottom end. Top end was refreshed with 3 angle valve job and all new seals. Motor has 400 miles on it. Just recently started smoking.
Mostly smokes after idling for more than a minute. As soon as I hit the throttle there is a huge puff of blue smoke.
Vents on valve cover have smoke coming out of them as well as oil dip stick hole. Lots of pressure coming out of dip stick and valve cover. When I put my hand over valve cover vents or dip stick pressure corresponds to the exhaust note.
Any ideas?

Driving nicely for 400 miles is probably the problem. It sounds backwards, but your kinda supposed to beat on it a bit. Your situations sounds worse than rings not seating though. Is it possible that rings were not installed correctly? Youve clearly got blowby from a piston/ring issue. Only way to get smoke into the crankcase.

I read all kinds of stuff, from drive it nice to beat the ---- out of it. To be honest I think its all bull ----. I drove it like I usually drive my cars. Normal. I kept it under 5psi of boost and tried to vary speed and not drive it on hwy for at least first 100 miles. Tried to accelerate and decelerate in all gears.
The engine was put together by a professional but anything could be possible.

Done it a couple of times now. Just don't want to do it again, that's all I am saying. Was not planning on this by any means.
Ita pretty much like rebuilding the block all over again. Head will most likely need to be resurfaced. All new seals on the block probably because it will has to come apart for honing. So I might as well just built another motor.

Tell us about the tune. I had a customer come in last year for a dyno tune, and while the car was warming up it started smoking from the valve cover vent, and then a steady stream of smoke from the exhaust started up. Revving it made it worse, not better. Scoped the bores and found chunks of ringland missing in #4. Traced it to a major overboost+detonation condition.
