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.

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.

ANSWER : It would be fairly easy for me to say you do need engine repair or replacement simply by your description and 30+ years of experience. However, you can try refilling the oil to correct level to see if it does start and/or sounds normal. Did the oil leak out all at once or did the level drop over a month ? Even if it was over the course of a month, a 4-5 quart oil loss over 4 weeks is still a substantial leak. The cause of the leak should be looked into before trying anything

Your best bet may be to have the vehicle towed to a local repair shop. Explain what happened completely. You can maybe negotiate a set amount of diagnostic time you are willing to pay to find pout if the engine is repairable or requires replacement.

ANSWER : Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.

Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.

To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.

ANSWER : It is possible that they put in the wrong viscosity oil. In rare instances, a defective filter will also cause low pressure. If there is too much oil, it will aerate and cause low pressure. Be sure the oil level is really not above "max". The P2187 code will appear if the oil fill cap is not tight but it will also appear due to a myriad of causes because that code only "generally" identifies a lean running condition. Consequently, numerous parts would have to be tested including the O2 sensor, gas cap seal, manifold air leaks, any vacuum leak anywhere including PCV and EVAP systems, exhaust leaks, and fuel system faults such as failing fuel pump, clogged filter and more. Since the car has relatively low mileage, you would not expect a failed oil pump, although the pressure sensor (or switch) could be bad. However, the occurrence of the oil pressure warning light is quite coincidental to the oil change, thus I would suggest bringing the car back and asking them to redo with a new filter and double check the viscosity of the new oil that they use. If the problem persists after that, you will have to test actual operating oil pressure (at idle for instance) as well as the oil pressure switch. Finally, if the oil pressure warning light comes on continuously, unless the warning circuit itself is malfunctioning, that means the oil pressure is too low to operate the engine without damaging it. Anytime the light comes on for more than literally an instant, you should shut down the car and thus an issue like this obviously has to be repaired.

If you’d like, a YourMechanic certified mechanic can come to your home or place of business to inspect the vehicle and perform an oil pressure light is on inspection to diagnose the vehicle and suggest potential repairs.

ANSWER : Hi there. There should be a select button with two directional arrows on the button. Push and hold the right directional arrow on the button and the dash should go from the odometer to the menu. Then scroll up by pushing up on the select button and you will be able to view the oil life percentage.

ANSWER : You might have a problem with the oil filter leaking when you rev the engine and increase the oil pressure. This can be from a collapsed oil filter media or excessive oil pressure from the engine. I recommend having the oil and filter replaced using a good quality filter and have the oil leak verified to be from the filter. Make sure to not run the engine low on oil. If you are finding you do not want to drive with the leak, a mobile technician from YourMechanic can come to your home or office, and replace both your filter, and oil.

ANSWER : Hi there:

It’s really difficult to tell you for certain what’s wrong with your Saturn without completing a visual inspection. However, if you had to add half of a gallon of oil, that’s not a good indication that internal components were not unharmed. I’d recommend that you contact a local professional mechanic as soon as possible to complete an engine inspection to determine of damage that has been sustained.
