Long story short, I removed the complete air intake from the AFM all the way to the bottom of the intake plenum. After doing a smoke test, it leaked from both intake gaskets.
Would you happen to know the length of the screws used to mount the bottom intake manifold to the engine block? I believe you should have 4 screws (M8) and two studs.
You may ask, cant you reuse the existing screws? Well, the PO only mounted the intake using the two studs. The four screws ain't there
Thanks!!
