Got an Infinti G35 6MT 2006
I just bought a G35 for $1500 with 224,xxx miles on it. The motor was still strong and the gears all shifted nicely. My mechanic told me to not burn the clutch as it was close to dying out. I managed to shift smoothly after a couple of days of learning cuz i wanted to treat the car right and make it last. Learned rev matching & downshifting too and started messing with it but had a few errors in the process of learning but managed to catch on.
So after a week of driving the g35, the car just suddenly died on the highway and I had to pull over. It happened after I was cruising at 70 mph on 5th gear, the car suddenly made noises below the center console area kinda below the shifter. It was like whirring, so I shifted back to 6th gear and the car was still making the strange noise underneath the shifter. The noise continued for a good minute or two until the vehicle just died out mid-driving. The steering wheel got harder to turn too.
My mechanic tells me the motor is locked due to the front end not turning. He also told me the oil was fine too even though it needed an oil change soon. He says I may have shifted wrong to have caused the engine to lock up which is a bummer to me because I've been practicing the shifts and treated the car like gold. I thought smooth shifting = prolonged life. But anyways, he says he'll charge me 500 to replace the engine (labor) but tells me he personally doesn't think it's worth it. However, I think the car is very beautiful and fun to drive.
What do you guys think caused my engine to die on me? Did i really f*** it up?
What route should I take from here. A new vehicle or fix the engine for most likely under $2000. The vehicle has very high mileage unfortunately. Opinions, questions, insights or anything would be great
