Question
hi i have a 92 seville the low oil pressure stop engine sensor went on. i was about a block away from home when this happened i decided to drive home sense i was close by. when i got home i heard sum rattling noise as i pulled up to my drive way i turned the car off and i wasn't able to turn it back on. i call a mechanic and he stateted it didn't have any oil at all and that was why this happened. i don't know anything about cars but i do know that it did have oil a week before this problem. the mechanic told me that the engine got stuck and that i need to replace it. he is selling me a engine with 72000 miles on it for 500 and 500 for the service. i don't know anything about cars and i don't know if he is being honest with me. please help me out it would be much appreciated. i want to know if i really do need to repair the engine or is their another solution to this problem?

Answer
Hello,

I just ran across a question similar to yours. Cadillac has not made a good engine since 1981 (even that one had problems). You should have the 4.9 in yours. Once the oil pressure light comes on, its all over and too late. You have less than 4psi and internal damage to the engine is imminent.

I love Cadillacs as well as know most of their flaws over the years. They are not a good car for someone who knows nothing about cars. Cadillacs can be money funnels.

The price you are being quoted for an installed replacement engine seems very fair to me of $1,000 total.

I would seriously suggest getting the car running and dump it and go with a Chevy or something. More reliable and cheaper to repair.

Good Luck!

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
