I missed a gear and may have blown my motor

95 5Spd 140K

Cliffs:
I went from the top of 3rd into 2nd for a split second, the car seemed fine on the way to work and leaving work then just died while driving and now it won't start. There no external fluid leaks.

When it happened, I went to fifth, slowly cruised, I didn't hear anything wierd at all. I believe the oil light came on a minute or two after it happened. I HAD to get to work and the car seemed fine so I drove there. I watched the temp gauge and it didn't move at all. I parked, the car idled fine and everything seemed the same but I thought I heard a little more ticking than usual. No leaks anywhere I can see. I get off work 8 hours later, check the fluids, they seem fine. I start the car, It starts right up! nothing unusual. I check the fluid levels again, everything seems fine. I took it really easy on the car leaving 3000rpm max, cruise fine on the beltline. I signal to for my exit, push in the clutch and the car dies, It kinda barely restarts, after cranking 4-5 seconds and I slowly release the clutch and the second the engine feels load it dies. I tried to restart 2 times I would "putt" a few times right after I stoped cranking and then die. It's definatly getting gas and I'm sure it's flooded. My battery is charging now..

Codes:
Cyl. 3 misfire
Camshaft pos
KS

Red oil light is on.


It's obviously not as bad as it could be, I bet I could get this thing running but it's in bad shape as it is. The previous owner didn't take good care of the car. The entire outside was terrible so I can't imagine the engine neglect. Let's say I bent a valve in cyl 3 so it's not compressing. Does that sound right? how can It drive completely fine for 30 minutes then just not work? Would 1 useless cylinder cause the engine not to start?

Any advice would be greatful!

The VQ's has known to take ore damage, so unless you could stop being and prove that it doesn't have compression in a cyl, then stop being a paranoid

well you might have overspun your oil pump (heard of that happening, dont know anything about it though), ive seen people take their VQ's up to 11000 and only screw the oil pump, but who knows, every engine is different.

cam sensor would prevent your car from starting up. Test and replace if needed.

The cam sensor wouldn't go bad from a overrev and It wasnt bad a couple weeks ago when I last checked codes. The cars been starting fine for months.

it wouldnt, but your getting a code for it, plus your car is not starting/hard time starting.
Test it with a multi-meter, and clean the sensor off. Reset ecu and see if the code comes back in a few days.
if it does, then replacement would be the next step.


ninja edit
: well the cam sensor is to determine TDC for when cranking, the over revving must have done something if you werent throwing a code for the cam sensor, then after the incident it is.

If the car does not start you replace or diagnose the things that prevent it from starting believe it or not the cam sensor can prevent the car from starting!

Other things that prevent the car from starting as it should are crank pos sensors and coolant temp sensor. You could also check the starter which I doubt is the problem and the ignition switch.

You seem to be a very close minded for someone that can't even put the car in the right gear

Negative. That's what the CPS (REF) is for.

By driving the car with the oil light on you probably did more damage to the motor than the over-rev did.

BTW, don't post again until you do a compression test. We can only do so much to help.

All my posts were made within 24 hours of eachother, I wanted to get a few opinions before doing anything. I still have to work I can't stop my life because of this, give me a break.
