I just want to know your opinions and see if the car I have is worth saving or should I just junk it. I have a 2007 Mazda 6 S 3.0L that I got a long time ago for free from a family member. The car was diagnosed with oil pan gasket leak, coolant leak possible from the water pump, and “transmission problems”.
I never fixed any of those problems because of the transmission. I just didn’t wanted to throw that money away since the car was free. When I first took it to a transmission shop they told me that the fluid was too dark and the transmission might be on its way out and that it is better to leave it like that, but I went ahead and replaced some of that fluid and the car still shifts without problems.
This, however created a new problem which is excess vibration in low rpms and first and second gear. I asked another mechanic to test drive the car and he thought it might be the transmission or motor mounts, which makes sense to me because you can clearly feel that violent shake when you put the vehicle in gear, but once you drive the vibrations will disappear.
He also gave me a quote for the water pump and I was planning on saving up to fix it. I drove this vehicle in this condition for over a month, topping up the coolant reservoir with coolant but eventually just replaced coolant with water because it was just leaking too fast.
Just a few days back I started noticing the heater was blowing cold air. The engine was warmed up but it took a while to start blowing warm air. The next day no heater at all.
Yesterday, I started noticing the low oil indicator blink, stay there bright red or disappear depending on whether I am driving or coming to a stop, so I drove home and shut off the engine because I could also hear either a tapping or clicking sound from the front passenger side and freaked out. I tried to start the engine again but it was difficult, so I bought some 5W20 oil and pour all of it on the engine. This time the engine started so I thought it was just the engine running low on oil.
Today, it started doing the blinking thing again. Smoke would come out from the front driver side of the vehicle. There is no coolant on the reservoir. Temperature indicator raises as I drive faster and goes down when I drive slower or idle. Heater blows cold air. The tapping or clicking is there again.
I know this is a lot to read and I apologize for that. If you have the time, I would appreciate if you can give me your opinion about this. Thanks a lot.
