OK 1998 Amigo 3.2 4x4 5speed 30k ( yes 30K )

The Has what souds like a sucking vaccum leak the nose isnt high pitched its more like a wooshing noise. I checked for a leak by spraying break parts cleaner around all the vaccum lines i could find and matting surfaces. I didnt find the source of the noise but i am sure all the lines are tight. However i found something disturbing. While checking i sprayed alittle Cleaner down behind the first cylinder on the driver bank between the vavle cover and the runners for the intake near the fuel injectors. In this location the Intake manifold meets the block and when i sprayed the cleaner there the Motor would bog down at idle. Regardless of the wooshing noise if the gasket for the intake manifold is in good shape this should not happen. There fore im thinking i have a leak between the block and manifold in that area. DO any of you guys know of a problem with the intake manifolds and blocks or the gasket ? I know this truck has low mileage and doesnt move alot so im sure that has to deal with it. Any suggestions ?
