2011 prius engine blow

My husband did a oil changed about 10 days ago. Yesterday morning while driving to work the engine light turned on and said engine oil pressure low. I continued drive for another 4 miles and the light changed to "Check Hybrid System". After another mile driving the car just stall and managed to pull over. I towned it to a toyota dealer and they disnosgtis we need to replace the engine. There was no oil in the engine? Is it possible that something defect with the oil pump system or the oil handling panel system? Just want to find out is it possible to blow an engine on a almost brand new car? Is there any factor with other part the car was build defective?

SOURCE: Oil pressure gauge

Low oil pressure is generally caused by internal engine bearing wear, not a "bad" oil pump... Pumps become "bad" when debris from a failed component gets into it, causing damage. (exception being pressure regulator spring/plunger assembly becoming clogged with gunk in engines that do not get proper maintenance; likely not your case)
Were there any tapping noises coming from engine when pressure was low? If not, The most common problem is the pressure sending unit, sending bad info to the warning light. If passage going to it or internal passage is gunked up, this problem usually disappears when oil is changed. sometimes the sender just goes bad, in which case, change it.
To get a proper diagnosis on your problem, have someone put a mechanical oil pressure gauge on it. This will read the actual oil pressure and will tell you a lot about the condition of your engine!
I have never seen a valve job that corrected any oil pressure problem. I mistrust anyone who would even think that!!!
Mlinimum low pressure at idle is 15 psi Max is about 60psi running (higher can explode an oil filter) A reading of 15psi indicates the beginning of a problem. although considered "safe" it is not good.

SOURCE: High oil Consumption, BMW M5

Look for Castrol TWS 10W60 Motor Oil. This car should not burn so much oil, you need to use a different kind. It is recommended by BMW as well. I also heard the VANOS isnt an issue anymore, can be fixed with a different MAFF. Good luck!

SOURCE: 2003 Prius Hybrid System Warning Light

My Toyota Prius hybrid warning light has come on three times in eight years. If I turn the car off for 20 minutes, the hybrid light is off but the check engine light is on. After a while, the check engine light goes off. I think this problem is related to moisture somehow entering the hybrid vent on the driver's side. All three times this has happened, the weather was wet. Kevin Cardiff

This could be a low oil pressure problem or a failing oil pressure sending unit (sensor). It could even be diluted engine oil. If it has been a while since the engine oil was changed, then change the oil and filter. If you still have the problem, then perform an oil pressure test and measure the actual oil pressure. It should not drop lower than 7 PSI at idle with a warm engine. If it does, then there is an internal problem with the engine like failing oil pump or worn bearings. If the oil pressure tests ok, then have the oil pressure sending unit replaced.

I had the same problem after 5 months of purchasing a 2011 Edge. The Oil Engine Pressure light comes on and stays on after driving 10 minutes and stopping for gas- it turns off shortly after I start driving again. I had a 2007 Edge as well and never had this problem. I just took the 2011 Edge back to the dealer. They could not duplicate the problem and instead reset all computer settings. The next day the same Oil Engine Pressure light came back on. Anyone out there with any suggestions?

Possible that the OIL filter is clogged and is reducing the pressure due to this when the engine is idling or in low RPM. So before you run the engine further and make it more damaging , it is worth to have the engine oil / oil filter changed. If there is still no result, check the oil pressure switch. If not the oil pump can be faulty. This needs a technical help and should be consulted.

Check engine light on after oil change three days ago


Your "check engine" light is an emission light. Oil is fine. You have to find the code to check whats wrong. Usually an engine light is just a tiny problem, but in other cases it could be anything from a sensor, to a bad cat converter. With a check engine light on a vehicle will not pass smog tests. You can turn it off by unhooking your pos side to the battery for about 3 min. Then you will have to drive it 30 miles non stop for the computer to put the code back in and the light will come back on

2005 Prius change in MPG after dealer service


What was the weight of the oil that was put into the engine when it was changed? Prius engines are VERY PICKY about the proper weight of the engine oil. Trust me. I see this quite often. The wrong weight oil can do bizzare things, and def lower your mileage. Something you can check: Take off the tube leading to the throttle body, and look down into the intake. Do you see any oil laying in the intake manifold? If so, you DEF have the wrong weight oil. This will NOT set a Check Engine light, either. Hope this helps.
