ok, so i just built my usdm 00 si b16a2 engine and got it in and running and it smokes a bit just like the white smoke n the morning when your car is cold but never stops gets a little worse in vtec but not bad. i didnt think anything of it at first cuz its freezing here and just thought it was because it was cold out side untill i noticed i was using oil. there are no oil leeks around the engine at all so something is wrong. the engine had 21K original miles when i did the build and have put about 2k on since. what all could it be, what should i check, and is there anyway i can tell what it is without tearing apart the engine? it is going through about a quart every 1-2 weeks. any ideas would be helpful. this is what i did to the motor- machine shop honed the block, polished the crank, narrowed the tops of the rods to fit new oem CTR pistons, fit new OEM honda rings. machine shop cleaned/milled the mating surface of the head, 3 angle valve job, new valve seals, new ITR dual valve springs. Then i reassembled everything with all brand new gaskets, CTR cams, skunk2 pro intake manifold, hondata manifold gasket. and i made sure everything was tightened to spec.
