Hello my car started to shot oil when in boost from the breather filter of my catch can ....

So i did a compression test and all four cylinders --->190 psi
What can do that without loosing compression ?

The setup is :
5-6000km since rebuilt B18c1 81,5mm pr4 pistons 9:1 compression
Stock rod
turbo t3/t04e 57 trim at 13 psi

The car never ran lean on the wideband or what ever ....

 

well thats wat is called blow by. usually if you don't have a catch can thats returns the oil the motor, the catch can fills up. so if you don't have a return line it then i would check the catch can every so often and empty it. also keep an eye on your oil level.

 

Well yes the catch can fills up... then i drain it weekly but normally before it wasn't blowing oil from the filter of the catch can

 

But if it were the rings or ringland it's not supposed to have low compression test result ?

 

leakdown test result :

Cyl1 :5% loss
Cyl2 :10%loss
Cyl3 :10%loss
Cyl4 :5%loss

That's not that much so still rings or ringlands ?
