92 Pontiac Grand Am stalled & leaked antifreeze and oil
Help! I just bought this car....as I was driving it home it stalled and would not restart. I looked under the car and noticed it was leaking anti-freeze and oil, but it did not overheating. I attempted to restart the car and a large plume of smoke came from the exhaust and steam was coming off the engine. Any idea what is wrong and how much it will cost to fix?

Rule out leak from water pump. What engine is it - 3.0 3.8. Could be intake manifold gasket. Have the cooling system pressurized, about 12 lbs. and look for leak, bubbles.
check oil for coolant in oil also. Possible head gasket leak.
believe me the motor in your car has spark plugs. unless the engine is a deisel which i highly doubt...you definitely have a fuel problem, or more likely a gas guage problem.where at a 1/4 tank it actually is running on fumes... have it checked at a full service garage..good luck..
Don't try to start the car anymore! You have blown your head gasket. Take the car to a mechanic and have them check the engine out to make sure you haven't done any further damage to the piston. If not, have them replace the head gasket and you should be good. Hopefully it's just the head gasket and you don't need to rebuild the motor. Hope this helps. Thanks for an honest rating and for using FixYa.
DO NOT DRIVE THE CAR until this problem is fixed! You could destroy the engine.
Many GM V6 engines of 1995-1999 had defective Upper Intake Manifold (UIM) gaskets (this is especially true for 3800 V6 engines). The antifreeze/coolant (especially orange DEX-Cool) will deteriorate the gasket material over time. If there are abnormal exhaust noises accompanying the leak, and/or the oil appears cloudy (check this immediately), you may have a blown head gasket or Lower Intake Manifold (LIM) gasket. Start with the UIM gasket.
The repair is detailed in the Haynes manual for that car ($17 at NAPA and Carquest), and (DIY) will take 5-8 hours plus a new gasket and RTV sealant (parts should be under $40 for all). A shop will charge $250-350 for this job.
