家园 您要看温度表。

看温度表正不正常。机油不够,温度上升,要小心。

You need to find out what is the noise. You can listen to the noise when your car engine is running with all windows down and then step on the gas pedal. Muffler noise should be coming from under the car or behind it. Engine noise should be coming from the front where the engine is located.

If you can confirm you have a leaking muffler, then don't worry too much about the oil leak as long as it is not too bad.

If the noise is truely engine noise, then make sure it is not too noisy. A little bit is ok. My car's engineer sound better right after an oil change, over time it get a little bit noisier.

I won't waste money on oil leak protector.

When I was driving those old cars, I monitor the temperature gauge and oil pressure gauge(one of my car has one) all the time. I never accelerate too fast. I usually slow down early when I need to stop so that I don't need to brake too hard. I also learn fixing my car on my own so that I don't have to pay someone else for their time. I know you didn't ask for it. But those are my advice on driving old car.

Good luck!
