    hiss at front of engine

    I have a hissing sound toward the front of my engine on the passenger side. I think it is lower possibly by the manifold or even higher more towards the turbo inlet. Im not sure exactly where because it only happens occasionally at idle. What do you think it is? I know this isn't a lot of information, but i need a place start.

    im not sure where to spray though because like i said it could be from the bottom to the top of the engine. Would i just spray everywhere?

    See if you can localize the noise with the motor just instantly turned off. If you can, it can be either air or a fluid. If you cannot, it is probably air. Knowing this, follow plumbing and tubing and exclude regions or components systematically.

    i know its when the car is on, because it does it on and off when idling. its like vacuum or exhaust but i just have no idea where to look for it.
