Ill try and cut the long story short my car was bellowing smOke1.8 zvh whitish blue smoke took off head cyl 1 was oily could the breather being blocked the small black ford thing off the rocker being blocked have caused a lot of oil to enter engine 2,3,4 look fine pistons look good checked breather on block they look clear the black breather pot looks sludgy like condensation the turbo was not the cause of smoke I replaced recently suspecting the smoke was coming from turbo since it got progressively worse until it would smoke on idle after aboute a minut running if the breather was blOcked would it cause this I haven't taken the piston out yet but all bores look okay and my gut instinct tells me they are fine but obv if it came to it I will push them up from crank case anyone got any ideas
