after a little while at idle, white smoke starts to pour out of the exhaust.
sometimes it goes away.
it doesnt smoke straight away at startup.
it turned up with good comp, a pressure test on the cooling system was fine. but the t-kay head check turned up CO in the cooling system. so i changed the head gasket.
only things i can think of are cracked head/block or the turbo has shat itself.
i just dont understand why it only happens after a while at idle and not all the time.
