Question about 1996 Cadillac Seville CA Value

Open Question

Blown head gasket or cracked head

I have a 1996 Cadillac SLS. It runs hot, loses coolant and emits thick white smoke from the exhaust. I see very little coolant on the ground therefor I assume it's sucked into the block. I also have a oil pressure problem. I love the car and want to keep it, but I don't want to buy another engine. What are my options?

    You are going to need to have the cylinder heads removed, and then have them checked at a machine shop that specializes in engine work, to check the heads for cracks. If the headgaskets are bad, and the heads are not cracked, a replacement of the engine would not be warranted. However, if you are getting coolant into the engine oil (the oil will look like chocolate milk); you are damaging the internally lubricated parts, and the coolant will wear them out very rapidly. Hope this helps. Thanks for choosing FixYa for an answer to your question. Please feel free to contact me if you have any other questions.

SOURCE: 2001 cadillac catera: oil in coolant?

The Problem, My friend, is a leaking oil cooler. this item is mounted, inside the engine, under the intake manifold. The cooler or the connections are bad. Coolant flows through the cooler, if it brakes then the oil will contaminate your coolant and make a mess.!! Have it checked. Must times is the seals at the pipe to cooler flange connector. will need new seals.. Hope this helps.

SOURCE: leaking coolant, oil, poorly running, won't shift into gears now

First determine where coolant loss comes from. I would not continue driving, till that step is isolated, or further damage will be done

SOURCE: my 2000 cadillac deville keep running hot when i

OK, check that the 2 fans are turning on when it gets to operating temperature. If not, replace the 3 or so relays that control the two speed fans on your car.If that doesn't solve the problem, then you may have to buy new fan motors and also have the harness replaced if necessary to make it cool reliably.

I had this problem on a 1997 Cadillac Deville Limousine that overheated over 157 deg. F and went into its limp mode for cooling the engine off by allowing 1/2 of the cylinders to circulate fresh air into the engine in case all antifreeze would leak out or the car would overheat.

Don't run the Northstar engine too long, more than 45 min. at a time in this limp mode.

Good luck on this repair of your Northstar Engine.

My car has white smoke coming from the exhaust


he causes of white exhaust smoke can vary; however, it is common to see white exhaust smoke when first starting a car, especially on cooler days. This is generally steam caused by condensation. As the engine warms up and the condensation dissipates the white exhaust smoke (steam) is no longer seen. If excessive white exhaust smoke is present well after the engine warms up, it is necessary to have the car inspected for possible internal coolant leaks. Indicators of an internal coolant leak include billowing white exhaust smoke accompanied by a sweet odor or a low coolant reservoir level. An internal coolant leak can also contaminate the engine oil giving it a frothy, milky appearance. Even small amounts of coolant entering the combustion chamber will produce white exhaust smoke.
One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder head, a cracked engine block, or head gasket failure caused by overheating. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. Dirty coolant, a poorly maintained cooling system, a low coolant level, or a non-functioning cooling fan can cause engine overheating. In addition, engine wear can eventually cause the gaskets to lose their capacity to seal properly allowing internal coolant loss. Intake manifold gasket and head gasket failures are two of the most common sources of internal coolant loss caused by engine wear.
Never remove the radiator cap or coolant reservoir cap while the engine is hot or running as it can cause serious injury; always allow the car to cool down completely first. Checking for a low coolant level in the reservoir is the first step in determining if coolant loss is causing the white exhaust smoke. If the coolant reservoir is at the proper level but excessive white exhaust smoke is present, a cooling system pressure check is required to determine where, if any, coolant leaks are located.

1996 Saturn sl2 smoke problem not head gasket no antifreeze seeping in valve cover gasket leaks and losing about a quart and a half of oil no blue smoke kinda white but heavy a little stops driving


White coming out the tail pipes is coolant/water. Doesn't mean the head gasket is blown, but you'll wish it was. Could be a cracked head. They can crack inside the intake or exhaust port. This would still give you a good compression reading. If in the intake, you would have a misfire. Exhaust you wouldn't. As far as the blue goes. It is mostly white in color, with a hint of blue color. Loosing that much oil would be a major leak or the rings are shot. Rings being shot, you would see that blueish tint in the smoke.

My Ford Windstorm Has White Smoke Coming Out Of Exhaust,ConstanLy,Thick White smoke


White smoke is an indication of water in the exhaust. This can be from condensation in the muffler, but that type of smoke usually dissipates after a minute or two of running. Constant, thick white smoke is usually a sign of water leakage into the combustion chamber(s), either via a blown head gasket, cracked head, or cracked block.

Nissan Maxima 1996 Engine oil turns milky white


Sounds like you may have a blown head gasket or a cracked head. There are test that can be done to check this the easiest and cheapest method I use is drope a few dropes of oil from your engine on something hot like the exhaust if it boils there is good indication there is coolant in your oil as the flash point of coolant is a lower temperature than oil

Milky oil dipstick, white exhaust smoke, coolant in spark plugs


*White milky oil on dipstick = coolant in oil.
*Coolant on sparkplugs = cracked head or blown head gasket
*White smoke = burning excessive oil in the cylinders, which can be caused by a number of things including valve seals, cracked head or blown head gasket.
***All three of these symptoms together, however, means its the head or head gasket. Both are costly but better the head gasket than the entire head.

Why does my engine emits white smoke when I press *** the pedal is the valvepiston ring sleeve at fault?


No. What kind of vehicle is it? White smoke in the exhaust is actually steam, which is caused from your engine burning coolant. The most common causes of this are blown head gasket or a cracked head. Check your coolant level and have a coolant system pressure test done to confirm.

If my car has some white smoke coming out the tail pipe and smell of anti freeze, but no milky in the oil. does that mean head gasket. it is a 1999 chrsler seebring


If you have steady thick white smoke and it smells like anti freeze it is most likely the head gasket. The head gasket can fail in different areas. If it has white smoke it failed between a coolant passage and the combustion chamber. If the oil is milky it failed between the coolant passage and an oil passage. Just because the oil isn't milky doesn't necessarily mean that the head gasket it's blown.

White smoke and smell of eggs


White smoke in the exhaust, more so on a cold start. That's steam. Water is getting into the combustion chamber. Most likely coolant.
Put your hand in the white smoke to capture the odor. (don't burn yourself)
What does your hand smell like? Coolant (anti-freeze & water) smells sweet.
Likeliest cause = head gasket. Possible = cracked head - depending on how hot it got. Less likely = cracked intake manifold.
Maybe a blown head gasket
