SOURCE: Coolant leaking from underneath car near oil pan.

THIS IS STRANGE, BECAUSE THE NEXT PAN BEHIND THE OIL PAN IS THE TRANSMISSION PAN. UNLESS MECURY HAS DEVELOPED SOME STRANGE SYSTEM THERE SHOULD BE NO WATER OR COOLANT ANYWHERE IN THAT LOCATION? IF THE PLASTIC PLUG IS LEAKING IT CAN BE FIXED BY REMOVING IT AND WRAPPING THE THREAD WITH TEFLON TAPE AND RE-INSERTING IT AND TIGHTEN IT. IT THE PAN ITSELF IS LEAKING, THERE ARE ONLY TWO THINGS HERE. ONE, YOU CAN RE-TIGHTEN THE BOLTS TO SEE IF THEY ARE LOOSE AND SEE IT THIS STOPS THE LEAKING. OR, IF THE LEAKING DOESN'T STOP, YOU NEED TO REPLACE THE PAN GASKET WITH A NEW ONE AND REFILL THE TRANSMISSION WITH NEW OIL. YOU MIGHT AS WELL CHANGE THE FILTER WHEN YOU HAVE THE PAN OFF, BECAUSE IT IS PROBABLY OVERDUE. I THINK YOU WILL FIND THIS LEAK IS A STICKY RED FLUID CALLED ATF OR AUTOMATIC TRANS. FLUID. THAT WILL NEED TO BE REPLACED. NEW FILTER, NEW GASKET RETORQUE THE BOLTS, IMPORTANT, DON'T WANT THAT THING FALLING OFF, NEW FLUID, YOUR BABY SHOULD PURR AND NOT WIZ ON THE FLOOR ANYMORE. NOT SURE HOW TO DO ALL THIS? BEAT FEET TO THE NEAREST PARTS STORE AND BUY OR ORDER THE CHILTON OR HAYNES MANUAL FOR 93GRAND MARQUIS AND YOU WILL HAVE PICTURES AND STORIES YOU WON'T BELIEVE! CAN'T GO WRONG! GOOD LUCK!

Start car and use a squirt bottle of water to wet the wires and coil, if you see it spark or run rough one or both are bad, repair the wires first as they are more common.

Mitsibushi pajero oil light time

White SWEET smelling smoke, or white OILY smelling smoke? If it's white thick SWEET smelling smoke, you have a blown head gasket - that's the smell of antifreeze burning in the engine, which it should NEVER do. If it's white OILY smelling smoke (smells a lot like diesel), then you're getting too much fuel into the cylinders.

If it's sweet-smelling smoke (antifreeze), pull the oil dipstick & check the oil level. If the oil level is HIGH and the oil looks like a mocha milkshake, that's absolutely conclusive - that's what happens when antifreeze gets into your oil, and it's nasty corrosive to engine parts.

I'm not at all surprised that the oil light is on if it won't start - you won't get much oil pressure until the engine is running.

I have a 99 Saab 9-5 2.3L turbo. When I shifted it would blow white smoke for a second. Yesterday it started billowing smoke then died. Now it won't start and it turns over very rough. Please help.

Generally white smoke is a sign of coolant in the engine.
Its possible you have blown the head gasket and coolant is leaking into one or more of the cylinders.
You could pull the spark plugs and check for coolant - also run a compression test.

My 2008 dodge grand caravan oil looks like lowfat light chocolate milk?

with 15 years experince as a mechanic it sounds to me that you have a blown head gasket that would result in antifreeze leaking into the oil system. which will cause what they call the choclate milkshake. the funny exhaust smell and white colored smoke is caused from the head gasket leaking coolant into the combustion chamber and when coolant gets into the combustion chamber it burns the coolant and forms a white smoke out of the exhaust that will have a sweet smell. replacing the head gasket and having the cylinder head checked at a machine shop will solve your problem. if you remove the spark plugs one at a time you will probally find one that is wet with a unusual color or may even find two spark plugs that way indicating head gasket blown between two cylinders which is most likely your problem. if not fixed soon driving will cause crankshaft bearing damage which results in engine lock up or crankshaft parts like a piston rod to start to knock or fly apart ruining your engine. i hope this helps you

There is white smoke coming out the tailpipe no smell of antifreeze

If it doesn't smell like sweet then you most likely got a bad tank of gas. Just to be safe keep an eye on your engine temp. and coolant levels.

1981 ford tranit van. every time i try t start the engine, white smoke comes from the exhaust in short bursts, then after a few seconds it dies alltogether.

Hi,
If the smoke is white then you have oil burning in the combustion chamber inside the engine and the spark plugs will be fouled. Remove the spark plugs and clean or replace then try it again, if it runs and it smokes excessively then you will need to get the engine internals looked at.
If you need more information let me know.
Thanks

Theres oil mixing with my antifreeze,why i smell antifreeze inside my car while driving

You could have two problems. First, does the engine require more oil than usual, is the oil level always low ? Does the transmission lose oil ? Could possibly be the trans. cooler in the rad. is cracked. Usually with a blown head gasket you get coolant into the engine, or burn it. ( white smoke ) Has the engine ever over heated ? On the smell part, this could be the heater core is leaking. Have a pressure test on the rad. to try and help find the problems.

Car failed for visable smoke 93 marquis

A temporary solution for removing oil smoke. (oil burning )
Use synthetic oil with 3 cans of STP oil treatment with oil level brought only to the add mark on the dip stick.

The synthetic oil will burn clear and the STP will reduce the oil burning to almost 0 for a day or two.

To reduce antifreeze burning.......put a rad cap on that cannot hold pressure and is vented to the overflow bottle......rip the rubber gasket on the cap in two...leave half there.
This will cause no pressure to build up in the cooling system and should reduce antifreeze burning greatly.

REMEMBER.....if you have filled the exhaust system with a burning product....antifreeze or oil.....it will take time to burn off and out of the exhaust system.

These are temporary solutions just to get you through the test.
You may need major engine work to correct a smoking engine for long term use.

Misfires in Cyl. 5 and 6, after changing problem continued

white smoke indicates the engine is burning antifreeze, you could have head gasket issue, if thats the case the antifreeze is getting in the cylinders and the engine is burning it. could be a stuck exhaust valve( i doubt it). find out from ford what that code indicates, that would be a better clue than tearing into the motor
