Car squirting oil and smoking

oil squiting from nuts and bolts in from on the block when I open up the hood and smoke coming out front and back.

My car has 1300000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hello. This is a sign of an oil leak. If the oil is squirting from the motor only when the car is running, this helps to narrow down where since that means it is coming from a place that is pressurized rather than a slow leak coming from the bottom due to gravity. The smoke is likely a result of the hot oil being burned off of the motor as it leaks. If you would like to have this problem diagnosed firsthand a certified technician from YourMechanic can come to your car’s location to inspect the oil leak and follow through with needed repairs.

Smoke often leaves car engines as a result of overheating. This can be caused by faulty wire casings, heated residues on the engine block and overheated liquids including oil, transmission fluid and brake fluid. There may also be a fault in your coolant system, or your engine may not have enough lubricant.
Cracked Gasket: The Core Culprit in Most Engine Oil Leaks

More often than not, a sudden oil leak after oil change is caused by a malformed or cracked gasket. Gaskets are usually made of urethane or rubber, and they can harden over time.

Common causes of oil leaks include degraded engine gaskets, leaks from the oil pan, or improper or worn out seals. An oil leak also can be caused by a loose or missing oil pan drain plug or deteriorated valve cover gaskets.
One possible reason for white smoke coming from your car`s exhaust is that the engine is burning oil. This can happen if the oil level in the engine is low or if the oil seal is leaking. If you notice that your car is burning oil, you should take it to a mechanic to have it checked out.
If Your Car Smells Like Acrid Smoke Or Burning Oil

If you notice the smell not long after an oil change, the leak might be caused by a loose drain plug or filter that wasn`t properly attached—or an oil cap that wasn`t screwed on tightly enough.

Engine Gasket

This is the number one area where oil leaks can develop and, we won`t lie, it`s devastating. There is a long seal between your cylinder heads, oil pan, and the engine block, and if this seal breaks, oil can leak into the cylinders and damage your engine.

As many classic car owners know, older cars are going to leak oil. Due to the technology of yesteryear, oil leaks are standard for most old cars and should not be a huge concern for drivers.
Oil toxicity: Oil consists of many different toxic compounds. These toxic compounds can cause severe health problems like heart damage, stunted growth, immune system effects, and even death.
One of the easiest ways to fix the leak yourself is to use a stop leak additive or high mileage oil blend. Such products can soften and condition your car`s rubber seals to stop and prevent further automotive leaks. It may take up to a few hundred miles of driving before the leak is completely sealed.
Burning oil is often the result of worn-out parts. For example, worn valve seals and/or piston rings could lead to your car burning oil. Both valve seals and piston rings work to keep engine oil out of the combustion chamber.
What does it mean when your car is leaking oil when parked? Oil leaks manifest in many different ways, but if your car is leaking oil when parked, the vast majority of leaks are due to degraded engine gaskets, oil pan leaks, or bad oil seals and connections. Your car`s oil pan is attached to the bottom of your engine.
The most common answer to, “Why is my car smoking but not overheating?” is that there`s a type of fluid that`s landed on the engine. This can be motor oil, fuel, transmission fluid, coolant, or even condensation. It can cause your engine to smoke because it`s burning off that fluid from the engine.
White Exhaust Smoke

White smoke billowing out of your exhaust means that coolant is likely leaking into the cylinders. This usually happens when there has been a breach in the head gasket, which makes the coolant create this white steam.

White Exhaust Smoke

If it`s a solid, opaque white, and resembles a billowy cloud, then this is a clear sign that there may be fuel in your oil pan since it isn`t hot enough to vaporize the fuel. This could result directly from problems with the combustion chamber.

A pretty common issue that occurs with engines that are running low on oil is a strong burning oil smell. If you`re driving and you start to smell an oily odor coming from somewhere, that`s usually a pretty good sign your vehicle is due for an oil change.
If it`s a little on the low side, top up the oil and check again the next day to see if the level has dropped significantly. Avoid adding oil and ignoring the fact that the level keeps dropping – oil leaks can be potential fire hazards so it`s important to ensure that everything is working as it should.
In the case of a blown head, external oil or coolant will leak out from the seams between the engine block and the cylinder head. These leaks are a sign of head gasket failure and a good sign you need to have any potential cracks and cylinder head twists looked at, immediately.
A small oil pan gasket or valve cover leak shouldn`t prevent you from driving as long you check your oil level frequently and add more if needed. However, an oil leak caused by a punctured oil pan or other major engine damage will usually require your car to be towed.
Q: Can I still drive with an oil leak? A: It`s always advisable not to drive if your vehicle has an oil leak, but short distance drives, less than 10 miles, are not as risky when it comes to lowering your oil levels to a dangerous point.
The most common cause of smoke under the hood is small amounts of motor oil or other fluids accidentally spilled or leaking from a bad gasket or seal onto a hot engine or the exhaust system. Those other fluids may include engine coolant, power steering, brake and transmission fluid, even window washer solvent.

Engine oil leaks are one of the most common causes of engine damage. They cause rapid deterioration of the engine and result in expensive repairs. Worse yet, engine oil leaks pose a safety threat. They may lead to the loss of control of the vehicle while driving.

think i put wrong oil in car went few miles lose power car dies oil in spark plugs still starts low oil blinking light before die.
ANSWER : Hello. If you put too thick of an oil in the car, then you may have damaged the engine bearings but this should not have caused oil to get in to the spark plugs unless the oil got into the intake of the engine or one of the pistons rings broke. If you ran it without oil and then tried to put oil in thinking it would be okay after that, then you were not that lucky and broke or damaged all of the rings on the pistons. If you would like to have this looked over, a certified professional from YourMechanic can come to your car’s location to inspect the stalling issue and go over all of the relevant systems for a better diagnosis.

I have oil smoking out of my oil dip stick and oil filler on my valve cover. Lots of smoke coming out of my PCV valve
ANSWER : Hey there. Worn piston rings create more crankcase fumes (i.e. the smoke you see coming out of breather tubes and orifices). This is called "blow-by". As long as the PCV valve stays clear, and the engine can handle the fume/clean air & fuel mix, then you should be fine.

This is a normal stage of wear as long as tailpipe blue smoke doesn’t become excessive or offensive. The rough running at a stop light may be an early indication of too much blow-by, although those 6 cylinders engines had trouble with rough idle/low speed because of the big differences in the distance between the carb and each cylinder (Cyl 1 & 6 distant, cyl 3 & 4 very close). Keep it tuned, and watch for slow degradation in low-speed running. If you notice this problem worsen or would like to have this checked, then have a qualified professional from YourMechanic come to your car’s location to inspect the smoking problem and follow through with repairs.

Oil was leaking, put in over 4 qts of oil and oil leak stopper. White smoke coming tailpipe,engine shakes, car dies. Oil leaking.
ANSWER : Oil additives are not recommended by any vehicle manufacturer for any reason. Additives that purport to resolve oil leaks are useless, a waste of your money, and may result in engine damage. Every vehicle manufacturer strongly recommends against use of these materials. There is only one recommended and approved repair strategy when it comes to oil leaks: fix the leak.

You can only add the manufacturer specified amount of oil to an engine. If you add too much oil, or too little oil, that will cause engine damage. You should check the engine oil dipstick to determine if there is presently too much oil in the engine. If there is too much, the excess will have to be removed to prevent engine damage.

The leak that you are referring to can be repaired if you request an oil leak diagnostic. If you have further questions or concerns as you decide what to do, do not hesitate to re-contact YourMechanic because we want you to make the most of your repair dollars and help you get the best possible results.

lost all oil pressure, replaced the oil pump, low oil sensor, oil pressure sensor, oil pan gasket,
ANSWER : The fuel pump will not stay on if you loose oil pressure. This is why it is shutting off. The loss of oil pressure may be from bad crankshaft bearings or camshaft bearings. The engine oil pan should be removed and the oil pump needs to be checked to ensure that you put in the pick up tube seal to the pump and connected the pump to the block. Then remove at least one main bearing cap and inspect the bearings for excessive wear and crankshaft damage. If you need some help with this, consider YourMechanic, as a certified technician can help diagnose the issue with your oil pressure firsthand and help you fix it accordingly.

My car is leaking oil i got an oil change for it last month but it is still leaking oil what will cause my car to leak oil ?
ANSWER : Most older cars have oil leaks. Sealing technology has just not kept up with mechanical improvements to engines so much so that leaks often kill engines rather than mechanical problems. So, it is not unexpected at all to have an, indeed many, oil leaks on a 23 year old car. Oil leaks vary hugely in terms of severity and priority of repair. Oil leaking onto a hot engine manifold is the worst case (the oil can start a fire; at best, you are left breathing oil fumes in the cabin, as the oil burns off of the manifold) while de minimus seepage of oil at the oil drain plug or oil pan gasket, while annoying and messy, if limited enough is not an emergency. Some leaks are easy to repair, while others literally require the engine to be removed just to get physical access to all the leak points. In your circumstance, if you smell burning oil, oil is probably leaking onto a hot engine part such as the exhaust manifold. A certified Mechanic, dispatched by YourMechanic right to your location, can perform an oil leak diagnostic and then let you know of your repair options and costs.

As far as the check engine light, that is not related to the oil leak(s). If you request a check engine light diagnostic, a certified mechanic from YourMechanic would use a code scanner to retrieve the specific diagnostic trouble code(s) from your car’s PCM that have caused the check engine light to illuminate. Using those codes, the appropriate individual vehicle components or sub-systems (often a sensor, circuit, and the like) are then carefully tested, based on specifications set forth in your car’s Factory Service Manual, to pinpoint the cause of the fault or the reason why the check engine light has illuminated. Once the faulty part or component is identified, it is explained to your satisfaction and the mechanic will let you know of the cost to repair. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Stop car check oil warning
ANSWER : This light will usually come on when one of two things are happening. Either the motor is in fact low on oil or the oil pressure sending unit is not working properly and may be producing a faulty reading. I would recommend first, to check the actual oil level in the motor by using the dipstick. Be sure the oil level reaches the "full" mark. If this registers as "full" then you likely have a faulty oil pressure sending unit. I would recommend having an expert from YourMechanic come to your location to take a look at your vehicle to determine what may be causing your low oil pressure light to come on.

just got a oil change Car engine temp got really hot, oil spilled under the hood, loud screeching and smoke when the car is on
ANSWER : Hi there. I honestly hate hearing horror stories like this and am very sorry this has happened to you. There are several things that could have caused this issue, ranging from the oil service place forgetting to put the oil cap back on, tighten the oil pan bolt or the oil filter was improperly installed; causing the oil to spray, increase engine temperature and many other possible damage to internal engine components. The first thing I would do is contact the oil service location and inform them of the problems you have experienced. They should be given every opportunity to resolve and repair this issue; or at least, have an "accident claim" filled out by you; as it’s possible that major damage may have occurred. If they are unwilling to help, I would set up an oil leak inspection from one of our professional mechanics so they can determine where the oil is leaking from and any other damage that has occurred. In the best case scenario, the issue can be resolved easily.

2006 BMW oil filter gasket keeps breaking and oil leaks from oil filter. Oil leaks only after starting car in morning. PCV valve?
ANSWER : Hi There,
It sounds like you may need to replace the oil cap o-ring. If you haven’t done this before there are two O-rings to replace; a small green one on the base of the filter cap stem and the large black one that seals the filter cap (which seems to be the one you are having issues with). The large O-ring sits in a small square-shaped groove that is at the base of the oil filter cap. It is very easy to not properly seat the large O-ring because the threads for the oil cap are quite large and will accept the O-ring if you are not careful. I would suggest having a professional from YourMechanic come to your location to take a look at your vehicle.
