Yeah lots of pics but not what I'm looking for, I noticed you also upgraded your entire fuel set up is it advisable to put an aftermarket fuel reg too? Or can the standard fpr handle the fuel?

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?

im gonna seperate the turbo from the mani n just plumb her up, this way smoke will come out either turbo or head.

and im only gonna put half the oil back in, i pray it was just to much oil in and it pushes past some stupid seal hahah.

yeah thats my next step but i noticed when i draied my oil i drained over 4Litres almost a ful bottle of oil n theres more to come out,

i should have checked it with much less oil in it.. could that cause oil burning, being that theres too much somewhere?

Quick update,

Turn the car on today and there was no blue smoke. Until the car warms up then the blue smoke lightly appears.
Its not a great deal to worry about but when I start to rev the engine then it blankets the garage.

Removed the oil cap were you fill the engine with oil just to see if there is any blue smoke or anything to give anything away that smokes in the motor however it appears fine there is no smoke coming out of the cup and there is some decent suction as the engine wont run without me covering the hole, like a vaccum leak.

I removed the exhaust manifold to see if there is any oil in the exhaust ports to show me that there make be a leakage in the combust chamber but it is all black and is dry as a bone which is probably expected which will probably burn off.

As i removed the turbo off, I removed the dump pipe off the turbo and inside the dump pipe it was slighly shiny with a skim of oil around the inside of the exhaust pipe. Which i thought was a bit weird. I can basicly wipe my finger in the pipe and my finger will pick up alot of oil.

As the car is reving whilst it is warm the smoke is coming out as i increase and hold the revs up high and then I let go to see were the oil is coming from.. underneath the car and its like little puddles of oil like its been spitting out.. slowly.

My head gaskit and head was done so my valve seals in my head should be fine as the head should be basically re conditioned, so that rules that out. If it was my pistin rings would oil get through that thick and un burnt? and land on my garage door, as it should of probably burnt up??

I am not sure if this makes sence to anyone? or am I sure if it is the pistin rings.
