    New Oil Leak

    Inline with my expectations of a GM, as soon as I did a plethora of maintenance work, a new problem surfaced.

    I have an oil drip coming from a hole in the side of the intake manifold(downstream of the throttle body) as indicated in the photo. 2007 3.7L I-5

    The breather on the top of the block is secured to the intake airbox upstream from the throttle body(another known drip spot).

    Any ideas?


    Thank you,

    I assume this is the giant plastic resonator on top of the engine, correct? Have you taken it off and inspected inside? I've been about to pour several ounces of oil out of the resonator. One was a vehicle with a head issue. Another was on mine where I get blowby (I think) under heavy loads/high RPM situations. The resonator has several chambers, nooks and crannies where the oil likes to collect.
