no you need to fix the cause of the leak

if you take it somewhere to get looked at. make sure they actually look at it. i found loads of people said my turbo seals wear blown. i changed the turbo have same issue still. now turns out due to my own testing i have either a smashed or worn piston ring. causing blow by. fills up intercooler then gets pushed up to the intake area and out the BOV when u give it a bit.

compression test it before they say its ur turbo neways.

I had same problem. Took a while to figure it out as the turbo was ok and an compression and leakdown test came up positive.

It only happened sometimes (the oil getting into intake) so was hard for me to replicate.

Turns out it was simply the infamous oil drainage problems from RB heads. Everytime the car was punted through a right hander the oil would spew out the passebger side rocker breather which sits lower than the other side.

so wot need to be changed? or what should i do?

You should take it to a mechanic, and get him to compression test each cylinder, to rule out a blown ring. Thats step #1!
