I would check for your oil filter leaking oil onto your exhaust down pipe
nope, i have checked the filter, and no leak from there,

because when i try put my hand, i feel theres gas/smoke burst out to my palm,from block
not from exhaust/header

blowby lol..

with or without any problems with the pcv box.. if it started to smoke recently? it would smoke even if the pcv box was fine..

try running the car at idle.. as u said it smokes from behind the manifold/below..

remove ur dipstick and check.. if it smokes? then its the engine

i have identified exactly wheres the smoke blow up from

that smoke blow up from the black box that PCV valve connected on the block

my mechanics didnt connect the hose from pcv valve to that black box, so the smoke blow up from there to atmosphere..

im curious , are there any problem /effect to performance of that beside emission ?

nope, im with NA setup

but in my case , the inlet on intake manifold plenum was used by something like compressor that help if i use A/C, because if i dont use that,rpm will drop when i switch on A/C because of vacum matter affected by high duration cam

so i cann't plug the pcv hose to intake plenum side,thats why the black box opened

do you have emission laws where you live? if not, some guys just attach a little air breather to the end of the hose
there s emission law but not too strict in other word no one care about that until this day
so i think i dont have problem with that.. o ic so i can put a little air breather

are there any effect to engine performance ? maybe dropping some hp ?if i keep that open
