Days before, I changed the engine oil in firestone, but soon after that I found some fluid leaking. ( I am so sure there was no leak before that, because my garage floor was always clean ). The leak was not serious, but it did made the floor wet over night.
Then I came back to firestone, and they checked my car and said valve cover gasket leaking. They asked for $300, and changed 1.VS50059 valve cover gasket set; 2. replace valve cover gasket; 3. replace spark plug tube seal; 4.pcv276 pcv valve. After all these work, my camry stop leaking.
But leak happened 3 days later. I was so frustrated,

and I came back. But they told me they could do nothing this time, because new leak start. 1. rear head gasket leak, 2.the timing belt cover leak. They told me the some other shops can do that for me but not firestone.
Now, the leaks start when the engine starts, stop when the engine stops, and about one minute one drop. Is this situation very serious? I just don't want to spend too much money for an old car and I don't want to know they take my money and tell me "they can't". The car, my 95' camry is in great condition, I trusted firestone before, but after that leaks...
Could somebody help me ?
