INTAKE MANIFOLD

The 3.8 windstar has a two piece intake manifold, If just the upper gasket needs to be replaced the book time is 2.6 hrs and if both the upper and lower needs replacing the time is 4.7 hrs and the gaskets are approx $33 for upper and $131 for both upper and lower plus coolant.

the labor at my shop is 3.0 for upper and lower gaskets and bolts.you must replace the bolts because they have a grommet washer that is also responsible for sealing.not sure on the parts prices though.
