Not knowing how exactly to get this information out there, but I think this symptom and repair may be valuable to other people out there.
Would one of you please make sure this diagnosis and repair is seen by others.
Thanks.
I was off at 1st by the OBD code, but your help and persistence won the day .
Thanks
Thank you guys for your advice.
I found my problem. It was a little deeper than the rotor and points.
I pulled the entire distributor apart. Clear down to the sensors.
What I found were wires that had deteriorated and had begun to pull apart. Exposing the bare wires. There were many. I’m guessing when the engine heated up the wire jackets expanded and allowed an electrical current to pass into the distributor housing.
I red necked the repairs by painstakingly wrapping all of the broken electrical wiring with electrical tape. I did this just to see if this was the problem.
She fired right up. Ran for an hour in idle in my drive. Then took her out for a drive.
Runs great.
I’ll be replacing the distributor with a new OEM part.
Thanks again for helping me out! Cheers!
Checked the distributor and points. There was some carbon build up on the rotor and two of the points. Cleaned them up and let the car run for almost 30 minutes. No check engine light. All seemed well. Dropped the hood to take her for a drive. I was cleaning up my tools before I left. Heard the fan kick on. Just before climbing in noticed my engine light was back on. OBD code was 4 & 8 again. Can one or both of the sensors be failing due to heat?
I did replace the O2 sensor. Runs for ten minutes then dies. Wont restart till it cools.
I believe i read the OBD code incorrectly. 4 & 8 not 48.
Distributor?
Mechanical timing?
Car sounds and runs great till it, well doesn’t. About ten minutes. Just dies. No noise no jerking.
Maybe just me, but the exhaust may have sounded a bit louder than normal.
ThanksThe o2 sensor was definitely part of the problem. Car starts runs nice, then after about ten minutes of run time. Dies abruptly and will not restart till a couple hours of cool down time. Ideas?
I can’t speak for your exact model, but often times a weep hole is built into the bottom of the water pump. Many water pumps will provide this to show an early development of a seal leak. This is a preemptive sign of water pump wear and or seal failure. While your system is hot or under pressure, fluid will leak out, but once the engine cools it will stop. This is the beginning of this symptom. Will only get worse as the pump gets older. Hope this helps.
