I have another problem, every time I put the intercooler pipes on the car it looses boost and power. I pull over to check the problem but all the pipes are still attached but oil is coming out of certain pipes and I was wondering if I have to have all the right metal couplers in the right place where the pipes have beads that the metal couplings grab on to so it doesn't have any leaks? What would cause the pressure to blow oil out of the intercooler piping to make it not run right and bog out all the freaking time.
