Question about Toyota Prius
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.

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!

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
