A pressure test on the cylinders will tell if you have a bad head gasket. If you hear a whistle sound near the intake gasket, spray WD-40 (or any type of petroleum spray) on the area and if there is a leak the engine rpms (or engine sound) should change.

How do you replace a manifold gasket in a 95 Ford Windstar?

"Manifold gasket" ? whick one? Upper intake MG,Lower intake MG or exhaust MG? I thinks you mean intake MG. The Upper intake MG is easy on. Just undo the bolt and clear the gasket materal, then replace new upper intake MG. The lower intake MG is a little bit hard. Carefully clear the old gasket material on the manifold and head, clear the bolt nad bolt hole in the head, then carfully install the lower intake MGand double check the coolant passage in ordeer to void the coolant leading. The last step is to torque corectly the bolt. good luck.

Should just be the gasket but check the upper side of the cylinder head while you have it apart to see if it has problems. Intake gasket leaks will present vacuum problems, if pressure is pushing air out of the affected area then it may be the head.

I'll assume Lower Intake Gasket, since they tend to cause vacuum leaks. Get a manual from Autozone and expect about 4 hrs labor, you need to take off the upper intake manifold just to replace the Lower Intake Gasket. Probably should change/clean the PCV valve while ur in there. Good luck, man.

Why are 3.8 liter engines more known for blowing head gaskets?

The 3.8 GM V6 is prone to blown intake gaskets much more than blown head gaskets. The blown intake gasket causes a loss of coolant which in turn causes overheating and a blown head gasket. The problem exists with most 2000 to 2003 vehicles equipped with the 3.8 Liter V6. There were defects in the upper intake manifold gasket, throttle body nuts, and the throttle body gasket.
