Just got the news that I have #8 burned. Compression at 70. My Aurora has 62,000 mi. Isn't this a common problem? Seems as though I've read about this in the past. Lucky, maybe until today.

Not to sound like an idiot, but what causes a burnt valve?

I have no clue. Haven't had repaired yet as I'm still in shock. I don't believe I'll ever know "why." I've read a lot on this website & I guess I should feel lucky. I've had only a few things to happen to my car, nothing major. I've noticed here that problems begin with mileage above 60,000. Maybe I should count my losses.

A burned valve can be caused by: 1. Too lean a fuel & air mixture. Too lean a mixture burns hotter than an evenly mixed one, or a rich one. That can cause a valve to overheat & burn. 2. Clogged cooling system passages around the valve seats. When the valve is in contact with the valve seat, it is cooled momentarily by the cooling system. If not enough coolant is flowing through those passages due to a clog, the valve won't be cooled adequately & will eventually burn. 3. Any dust particles which get past a damaged or inadequate air filter could wind up on a valve seat and prevent the valve from contacting the valve seat correctly. This can cause valve damage. 4. Knocking can cause valve damage. _________________ GM!!! BRING BACK OLDS!!!  |

Thanks Marc for the info. I wasn't aware that "any" of these symptoms were happening. The car has been serviced regularly. There was no apparent problem when I parked it & then 2 hrs later it was "missing" when I drove it. In June, I responded to the recall on the Fuel Rail repair. Is there a connection?
Thanks !

There could have been a connection between the missing and the fuel rail problem if the fuel rails were leaking so badly that there was a loss in fuel pressure to the fuel injectors. Also, those fuel rails were made out of nylon, which being a basically soft substance, could have warped causing a clog that could cut down on fuel pressure. _________________ GM!!!

My panic is over. Took my car to a certified Northstar mechanic (his comment when I drove in, "God, I love these engines".) He checked the compression. PERFECT ! My husband had seen the gauge at 70 but a compression check was not done on other cyclinders at the other shop. Our MISTAKE ! Obviously we had a bad reading. My problem was a bad fuel injector. Where would I be tonight "if" I had let the other guy tear into my engine?  Hmmmmm, MURDER ONE or SUICIDE ? One more time, this is the most AWESOME car in the world ! |

Hi, MemphisMam, 62,000 miles on a 96. I have nearly 125,000 miles, double yours... envy envy Are you going to pop on over to introductions and tell us about your Aurora with maybe a piccy or two. Good news on the Burned Valve being just a bad fuel injector. Do you st..st.. stutter or was judy taken?  |

Now don't get me started talking about this car. I absolutely love it. I was in a panic when I was told I had major engine damage. I can't think of anything I had rather do than hit the interstate in this car. Just give me a reason to pass someone!!!!!!!!! The power of this engine is still as exciting as the day I test-drove it. SUPER, SUPER Car !
I'm new to this site & haven't done a profile. I wanted information & quick, by fellow Aurora people. Let me figure out the details & I'll post a profile & pic.
