Oil control rings gone bad??
Rebuilt block last september put rough 300-3500km on it , no smoke on startup never had a issues with cold or hot starts its a half bridge not over ported into oilcontrol ring path what so ever
after storing the car over the winter. It now puffs smoke on start up but clears in 5-10seconds holding rpm at 4k yeilds no smoke what so ever,
Only reused peice in my build internally was oil control casings the orings are brand new! So what happend?

did you use some generic kit you found like those ******** selling red silicone oil seals? because those are NOT the right seals.
viton and HNBR do not come in red, HNBR is green and chemical resistant viton is a matte black. glossy black seals could be nitrile or buna which are also the incorrect material that some of these asshats are passing off on people.
extremely worn irons will also allow oil to leak down when the engine is off, which is probably what you're getting, in which case just run it til it craps itself.

the viton seals have a tight fit to the rotors and do not spring out as well as they should, sometimes the rotors are in such a position that a little leak down is normal. it's a compromise versus using the craptastic OEM seals that do not seem to last as long as they should.
besides, a little extra oil for the apex seals during crank has never been a bad thing.
