Question about 2002 Toyota Camry

1 Answer

Significant engine damage from oil change

Recently our car broke down out of state and was towed to a Toyota dealership. The Service Manager wrote that "at the last oil change, the shield inside valve cover was bent down to cam. Wore shield off. Broke off. Fell down to crank, de-railed timing chain causing engine to jump time." The car was repaired and we were told there may have been further internal engine damage and to take it to our local Toyota dealer. They told us that the engine will need to come apart for further diagnosis - that there is internal engine damage. Both dealers have heard of this problem before. Have you heard of this problem and who would be responsible for the engine repair? Any suggestions or comments would be appreciated.

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.

    I did get thru to my friend in California.He states that this is a known issue, and Toyota has released a Technical Service Bulletin (EG007-02) regarding this issue. The gist of the bulletin mentions that the baffle in question can be bent during the oil fill proceedure, and damage can occur if the baffle is damaged.

    New one to me. But, this solidifys my thinking about how it happened; it was the oil change guy jammed the nozzle too hard into the oil fill hole.

smoke is a bad sign, on low mileage engines say below 250,000 miles and with noise worst. there must be no noise, on this engine.

Nissan sentra 93 head gasket. Ga16de.

I would have the car towed/ flatbedded to a mechanic that you trust or one who has been recommended by a close friend or relative. It takes me about 4 hours to do on a Honda Accord or my other car, a Toyota Sienna.
It is pretty straight forward if you have the tools, plenty of rags & 6 quarts of oil. ( either 5w30 or 10w30 will work on most cars. ) You should get the replacement gaskets at a dealerships Parts Department.

There are many things that can cause oil loss. The most common are a loose or missing oil drain plug, or a leaking oil filter. With either of these problems the oil can leak out very fast. Your mechanic will locate the oil leak as a first step, then I am sure they will then proceed to inspect the engine for internal damage due to oil loss. I would recommend a leakdown test to check for piston or ring damage, also you need to pay close attention to whether the engine has any new noises. If the leakdown test shows good results, and there are no new noises in the engine, your engine has a pretty good chance of surviving this ordeal. There are many possibility for the leak source, like worn seals, or the tow previously listed items, be sure to repair the engine where it does not leak, because loosing the oil can destroy the engine. Good luck with it.

2003 VW PASSAT. Check engine light goes on and

8.5 hrs + parts sounds about right. But why would a 7 year old cars oil pump fail? They usually last a lifetime. Has there been a lubrication problem? Low oil, cheap oil, wrong oil? But then again my daughters 04 Toyota needed a valve job, head gasket and water pump recently. I'm doing 90% of work and it still cost about $2000. Her problem was bad oil!

Am I getting taken advantage of?

Was the oil changed at that dealership? If so they may be trying to cover up a mistake they did when they changed the oil. Whoever changed the oil may have forgot to put the oil back in, (I have done this myself, they brought it right back and no damage done.) The drain plug or oil filter may not have been tightened and oil leaked out causing engine (piston) damage. I strongly suggest you have the car towed out of there, they might confess if it indeed it is their fault, knowing whoever sees it will have a good idea what happened. Keep in mind I don't have any BMW experience and haven't seen the car, but an engine is an engine, and what you are telling me doesn't sound right.

1991 Toyota Corolla loud and sluggish

You need to do a compression test on the engine cylinders. It appears one of the cylinders is not firing and dragging the rest of the engine down in power. The compression test will show if one of the cylinders has a problem.
