If you need to ask this question, then I suggest you should contact you car repair centre and get them to do the repair. It is not easy to do this work, you need special tools and it is best done on a car hoist.

Backfires and stumbles when gas pedal is floored

There are a lot of diffferent things possible, the backfiring is usually caused by a timing issue. Which could also cause some of your loss of power, but not always. Try checking your fuel pressure to see if there is a clog, also your timing is computer controlled so this means your timing chain is worn spark plugs and wires could be bad or you have a cracked distributor cap rotor bug bad, or even a bad distributor or even as simple as wrong ground placement for motor. Best choice is to start small and then work your way up. Also if disributor has ever been taken out then you will have to reset your oil pump drive because your distributor runs your oil pump with your cam-shaft.

Stupid question but I'm just not sure. What does it mean when the oil light is on and it makes a long beep like noise from time to time? Should I only get an oil change?

It's an indication of low oil pressure. Could be low on oil. Could be the oil pump. Could be excessive engine wear in the main engine bearings. As the engine runs the main bearings (in the oil pan and between the piston rod bearings) create pressure. If a couple of quarts of oil don't turn it off (if it's low), it could be the pressure switch being bad and sending a false signal. Lastly, the main bearings and oil pump. That's cheapest to most expensive.
Hope I helped. If so please rate my answer, and leave a comment. Thanks.

Car starts and stalls. Don't hear sound of fuel

The mechanic should check on the fuel pump and the Idle of the fuel pump . if the fuel pump is malfunctioning then you have to repair it.Then also the throttle if the throttle is being worn out or malfunctioning then you have to repair or replace it.The Idle should be adjusted because of the engine is stumbling .the reason why the engine is stumbling or the car over heats is that the fuel pump is not functioning good or there is a problem in the fuel pump.and also it is the reason why the engine light goes off when cold because of the engine problem is in the fuel pump.such fuel or is not entering or going to the engine.

White coloured engine oil, overheating

White oil means water or coolant is leaking in via Head Gasket Failure or a crack in the head. Along with repair - be sure to have each cylinder compression tested to see if there is a crack that has developed.

Significant engine damage from oil change

Thank you for asking my assistance. I will try my best to help you.

I have been in the Toyota biz for the last 14 years, and, unfortunatly, have not ever heard of this issue. That being said, I do have connections in the engineering dept at Toyota, and on Monday, I will call out to the west coast and inquire further for you.
Now, to the issue at hand: The shield that was bent down is secured very well to the underside of the valve cover. To bend that device, I can only guess that when the oil was being put into the engine via an oil pump, the nozzle of the pump was *** jammed *** down onto the shield, and broke it loose from the internal retainers under the valve cover, and contacted the cam; this is very possible...I agree with the statement that your SM provided, however, further engine damage? Removal of the oil pan would be in order, to determine if any more pieces are there. Doubt it, though.
And, to answer your last question, the responsibility of the cause for failure is your oil change guy.
He bent/broke the shield, and caused your problem. I hope this has helped, if you have any other comments or questions, please feel free to repost.
