Is it bad when oil gets into the throttle body?
In November my throttle body was acting up. Lightening bolt n traction control light came on. I had it cleaned and all was well. 3 days ago it happened again. This time worse, where it wouldn't drive right, made noise, had to get it towed. Engine light never came on. I had the throttle body replaced. The mechanic told me there was a little oil in the old throttle body and that my engine, i guess, could have blown up. Now I am really worried about the oil that was in the old throttle body. He said the new one could last 6 months or 6 years. They don't know how oil got into it. Maybe
Experienced mechanics share their insights in answering this question :
Hello,
I believe what you are describing is a problem with your PCV valve. A bit of oil in the throttle body is not going to harm your motor and is certainly not going to cause it to blow up. At an idle, the PCV valve restricts air flow, to reduce this problem. At high manifold vacuum (idle), a spring loaded valve is drawn up and partially restricts flow to the crankcase. The PCV system is relatively simple. An inlet hose connects to a filtered air source. This is used to supply clean air that is drawn through the engine. Most of the time this air is supplied through the engine air filter. On a few designs there is a separate inlet filter that cleans the incoming air for the PCV system only. This filtered air flows through the engine, picking up fumes and vapors. The air exits through another hose, connected to manifold vacuum. The flow of air draws fumes from the crankcase and burns them harmlessly in the engine. This also creates a slight vacuum, relieving any pressure that may build. Negative pressure helps to prevent oil leaks and oil consumption by the engine. The PCV valve also helps regulate the amount of air flow, which helps prevent oil being drawn out of the engine. When the PCV valve is not working correctly, this will cause an imbalance in air flow and vacuum causing the check engine light to come on. i would suggest having a professional from YourMechanic come to your location to take a look at your Jeep.

Yes. Oil in throttle body passages can cause idling problems. It also restricts flow through the intake, reducing power.
However, excessive crankcase pressure can cause oil to be pushed out of the breather and into the throttle body. This can be caused by worn rings or worn valves, oil sloshing (hard cornering), or too much oil in the crankcase.
Common symptoms
Throttle body and electronic throttle body issues can result in the engine stalling, failing to start, warning lights on the instrument cluster, and hesitation or power surging on acceleration.
Filth, carbon, and dirt can build up in the housing creating problems with air flow. Known as coking, the normally smooth service for air to travel becomes full of gunk and creates an imbalance. This interrupts that perfect mixture of air and fuel which can cause the butterfly valve to get stuck.
This ventilation system manages the effective removal of combustion gases between piston and liner while allowing a very small amount of oil to escape past the pistons. Such a small blow-by is completely normal.
On many engines I`ve seen coolant is circulated through the Idle Air Control valve and the throttle body.
Take the snorkle off the throttle body. Spray brake cleaner on the throttle plate. Scrub plate with a brush. Spray the brake cleaner again.
If you notice that the gears are not changing properly, get the throttle position sensor (TPS) inspected. A good mechanic will clean the throttle body during a tune-up.
Fuel injector nozzles can become clogged over time, which can lead to a sputtering engine, slow acceleration and the car not having enough power. Fuel injectors can be cleaned if the problem is caught early, but as the conditions worsens, the injectors may have to be replaced.
The throttle body controls your engine`s air intake, so keeping it clean is vital maintenance to keeping your car running smoothly. Throttle body cleaning is a necessary part of vehicle maintenance since the throttle body plays a significant role in the smooth running of the engine.
Here`s how the throttle body gets dirty. When an engine shuts down, hot exhaust gases and unburned fuel float to the top of the engine. As the vapors bake from the engine heat, they form black sooty carbon deposits inside the throttle body.
While throttle-body cleaning is good preventative car maintenance, it should also help engine drivability. In fact, if you`ve noticed a rough idle, stumbling initial acceleration or even stalling – all when the engine is fully warmed up – a dirty throttle body could be the culprit.

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.

Can I ride my car with a bad oil pan for at least a month until Ican get the MONEY TO GET IT FIXED
ANSWER : Hello. If the mechanic at your garage is telling you that the oil leak is severe, I would highly recommend replacing that as soon as possible and not to drive your vehicle until it has been fixed. Leaking oil from a cracked or damaged oil pan or rear seal can increase due to heat and excessive driving. It also will cause internal component damage as the engine will rapidly loose oil pressure and lubrication. An oil leak from the pan is one that should be resolved ASAP and without further driving if possible.

Is it bad to drive a car with a bad throttle body??
ANSWER : Hey there. This may not immediately affect your car’s engine. However, it will continue to cause intermittent misfires and will gradually get worse. This may also have an impact on other parts as well since the missing cylinder will still be receiving fuel. This fuel only has one of two places it could go: either out of the exhaust as raw unburnt fuel causing damage to the catalytic converter (which may also trigger more fault codes such as the O2 sensor), OR this fuel will end up down in the oil with the oil which causes the oil to break down. When this happens, the oil loses its effectiveness on protecting other vital engine parts. For more help, I would recommend having an expert from YourMechanic come to your home to diagnose and repair the misfire for you.

Low oil pressure light comes on when idle. Check engine light is on as well. Both came on after getting an oil change 3 days ago.
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.

car burning too much oil and can’t find where it’s going
ANSWER : The engine is sucking it in most likely. The oil control rings are bad or the intake valves are leaking. You should have a mechanic check the intake PCV system to see if there is a problem. After the diagnosis of your leakage, a certified mechanic can make necessary repairs.

I am upgrading my 2007 GT’s throttle body to a BBK 62mm throttle body.
ANSWER : Hello. The meter setting will depend on what BBK requires you to set the throttle body at. If the setting is voltage related then you need to set your meter to DC volts. That is usually what they recommend. If it is a resistance reading that they need you will set it to Ohm’s. If this is something that you would prefer to have done, consider YourMechanic, as a certified mechanic can come to your home to adjust this and insure a proper replacement of your throttle body.

I have a bad throttle body, so instead of paying the dealership ridiculous prices, I order a throttle body myself.
ANSWER : After you replace the throttle body then all you have to do is turn ignition on with all accessories off. After 29 seconds of not touching anything the engine computer will relearn the new throttle body. Leave it on for at least 2 minutes before turning off. Start the vehicle and see if vehicle idles good and throttle works before driving. If no Check Engine Light comes on then you are good to go.
If you run into any problems or decide to get some help with the job, consider YourMechanic, as a certified technician can help ensure the correct installment of your new throttle body.
