okay so after running the motor for 5-10 mins and the smmoke got a little too much to handle i shut her of n removed the exhaust pipes and turbos together, to my suprise the exhause ports are just black but the dump pipe was soaked in oil.

sooo... after realising i added nearly 4.5L of #OOPS# quality oil i drained her and filled half back into see if she still spits out oil, and she did spit oil but only when boost was up, i checked all my intercooler pipes but thre clean as new,but the rear of the turbo is just saturated in oil,this amount of oil can not pass the cylinder head this wet? so ive come to the conclusion its gotta be the turbo, because when i looked into the exhause ports i saw the exhause manifold was dry just like the head,my sparks were the same colour as my exhase ports with no oily substance..

sorry for the essay but i think its clear that im up for a bored out T25 ballbaring one,

if i had the entire exhaust system up with the cat on would this smoke reach out the tips at the end and pass the cat convetre?
