Engine Mechanical problem
1996 Nissan Sentra 4 cyl Two Wheel Drive Automatic 200K miles

I bought this car new in 1996. I have kept up with regular oil changes and stuff. I had a check engine light on last year, I took it to 3 different machanics till finally months later they found it was a sensor and dry rot hose. It seemed the car ran like new for about a month, but then my husband checked the oil but forgot to put the oil cap back on after adding oil, I was driving for over an hour before I stopped and noticed smoke and smell from under the hood. So I replaced the cap, filled up the oil and drove another hour to get home. I then drove the car again in a few days, but the smoke smell was making me sick, so a friend said he would clean the engine, and he used a car wash, well when I went to drive home it had no power, and was running so rough, so I took it to a machanic and he found water in the spark plug area, and blew it out with water. The car ran great home. A few days later it wouldn't start, I had it towed to the shop and they tell me the motor is blown, I need a whole new engine at 3,000.00. My question is which event caused this motor failure? Was it my husband forgetting the oil cap? Was it the friend who washed it in the car wash? Or was it just a coincedence that it happened during these other events? And is 3,000.00 a reasonable price to replace the motor?

Thank you for your reply to my situation. I called them and asked them, and I was told the engine had less than 30 psi when tested. So I would need to put in a new engine.

In your first post you said, “it ran great home, a few days later it wouldn’t start.”
If you mean it ran great up until just one day out of the blue it wouldn’t start.
And
The engine has less than 30psi (assuming you are talking about a compression test. And assuming that the engine has less than 30psi from each of the 4 cylinders)

About the only thing that could do that would be the timing chain breaking or some other problem with the valve train.

Sadly, if that is the case, a whole bunch of stuff inside your engine got damaged.

I can at least put one question to rest.
Your husband and car wash friend did NOT have anything to do with it.

Thank you so much for answering my question. Yes it ran great until the day it didn't start. Yes there was less than 30psi in all 4 cylenders, and yes that was discovered with a compression test.

Thank you so much for the information. I didn't get mad at my husband, but there was just this whisper in my mind, that I might be walking because of him. Now I can just let it go.

After hearing you confirm what the mechanic said, I decided to just buy a newer car.

Thanks again.
