Thanks very much for you help maximvsv.

I didn't notice any cracks in the hose that goes form the intake box to the engine, although I couldn't remove the engine cover as the aftermarket clips I put in were being stubborn. Anyway, I dont' think it has cracks in it.

Additionally, I removed the housing (lower portion of the box) and checked the hose that runs into it from the side of the engine compartment. I didn't notice any cracks in this hose either when feeling around/looking inside it. I also didn't notice any cracks in the box itself. And the box (before I removed it) seemed like it was sitting firmly in place.

Could the rubber (that's part of the lower portion of the box) that surrounds the hole that the hose (from the side of the engine) fits into be the problem? Does this rubber surrounding get worn over time thus allowing air to seep through?

Also, how tight do the bolts need to be that hold the box in place and attach the intake hose to the box? I didn't want to overtighten them and crack the plastic.

Thanks again.
