I have done six gasket jobs on the 3.8. I did not have to have any of these heads resurfaced,the were just bad gaskets right from the start.
Use your search engine,type in torque specs 3.8, then choose the first one on the list . All Ford mustangs 3.8 specs. these are the specs i used on all eight cars and all worked fine. This is basically the same motor but turned to drive rear wheels instead of the front.
6 4 2 8
5 1 3 7
Step 1: Torque from 47-53 Nm (35 to 39 Ft/Lbs)

Get a shop manual. This is a complex procedure.
NO get it fixed or you will be replacing an engine $$$ Soon.
On the Villager, replacing both gaskets is most easily done by removing the engine from the vehicle.
The head gasket is gone and water or coolant has mixed with the engine oil. Replacing the head gasket is no big deal.
if it is pumping out when you rev engine then you have a blown head gasket
If you have coolant on the top of the engine it could be a leaky thermostat housing or a leaking intake gasket.
It's supposed to do that.
The Ford Taurus for the most part has a V6 engine. It has 2 head gaskets. Some very early model Taurus's had 4 cylinder engines which had 1 head gasket.
You do not need any special crankshaft installer, when replacing the head gasket. The crankshaft and the head gasket are on opposite ants of the engine.
Your question is best answered with" purchase a manual"! Reason being, looking for help with torque numbers also requires sequence. Without the proper sequence, you will destroy, at the very least, the head gasket. an inexpensive manual can be found at all patrts stores.
