    The 5.7 tbi is forming a small puddle of oil on the drivers side. It ooks like it couldnt be coming from the valve covers because thers a lip between the manifold and valve cover and its dry there. It seems to be weeping from the middle manifold bolt. I am not chevy savvy , but wear would you start in stopping this leak?

    The middle manifold bolts go through a hole in the block flange, and the bottom of the hole is open to the flow of oil through the block. When these inner bolts are installed, they should have a glob of permatex or other sealer on the threads. If they aren't sealed, oil will travel up the threads and weep onto the manifold.

    You can probably just take the bolt out, add the permatex sealer on the thread area, and put it back in the engine. If you have an aluminum intake, make sure you get everything torqued properly and evenly, so you don't warp the intake.
