It's probably the turbo you're hearing. They spin very fast and make a noise like that. Ever hear an 18-wheeler go by you and accelerate and they make that high-pitched whistle? That's the turbo spooling up. Now, if it sounds like a dentist's drill, that's usually a sign that the turbo is failing, but I'd bet that since your car is under four years old, as long as you've kept up on the maintenance, it's the normal turbo spool.

an intercooler will cool the air that the turbo has compressed(when you compress air it gets hot)you will notice the difference......but hard to give actual increase in bhp.your acceleration times will drop as well.

Remember, what is heard as turbocharger noise may not be caused by a noisy
turbocharger. Before replacing a turbocharger perform the following diagnosis.
A. If a loud whine or whistle is heard during acceleration and increases or decreases with rpm and load. This condition is most often the result of a loose clamp/hose at the turbocharger compressor outlet, charge air cooler inlet, outlet or at the intake manifold.
1. With the engine running at idle and the transmission in Park or Neutral with the parking brake set, feel for boost air escaping at each connection between the turbocharger compressor outlet and intake manifold. For limited access areas, spray soapy water on those connectors and look for bubbles.
2. Check the exhaust manifold and exhaust system for leaks.
I hope this helped.

hi the clearance on these will be 0.25 hot ( just run ) and the reason why you have oil coming out from dip stick is either you have too much oil in and need to drain some, or somewhere on the vacuum system you might have a blockage which in turn is casing a pressure build up and is forcing the oil out...hope this helps

Welcome to Fixya
Error 41 is the butterfly spindle in the intake manifold just below where the hose from the intercooler joins. It should be open when engine running if it is closed it will cause boost issues and running problems.
Thank you for using Fixya!
