Sup guys?

Long story short, I was driving to vegas on thanksgiving day and when I got to 15 freeway, I floored the car in order to pass a car and suddenly the car bogged and lost power. I also noticed that the exhaust note changed, Check Engine Light came on and there's a loud rattling coming from under the car. The car still drives but it lacks of power and something smells burning. Also, when I pulled out the transmission case dipstick, I can see some vapor coming out of it. Now everytime I start the car, a blue-ish smoke would appear and it smells differently than before.

Please watch these videos and let me know what you think is wrong with my car. Any input will be greatly appreciated:





The car still shifts fine into every gear and the rattling would sometime go away during acceleration, but as soon as you let off the gas, the rattling comes back.
No oil dripping from under the car. For the past couple weeks, I noticed that the car would sometime shifts earlier than it should (lag) and I'm not sure if it has anything to do with it.

Thanks for your help.

Check the codes. How does the coolant look? Doesn't sound good...

 

Might be something to do with ur O2 sensors or catalytic converters. If ur throwin codes have oriellys or autozone connect u to a diagnosic scanner

 

Hopefully it's just a cat problem. Kind of sounds like a Jeep Cherokee. Also check the oil it sounds kind of like mine did when I had a rod knock.

 

did you check the exhaust? sounds like a exhaust pipe may have busted before the o2 sensors causing the car to run bad just a educated guess from your story

 

blue smoke? pistons giving out? how many miles on the car?

 

Compression check, leakdown test, and if those turn out fine. Take the cat out and see if that helps. But since your burning oil, I would think its something internally (crossing fingers that its not). But good luck too ya

 

Need the codes first before we can proceed or else its just a guessing game.

 

Any issues with power steering fluid recently?

 

Guys, thanks for reply, some quick notes:

-200k miles
-power steering leaking and have been refilling ever since but it works just fine
-recently the "castle" light came on (radiator I believe) but it no longer appears after filling it with more coolant
-blue smoke not too thick, only during cold start
-as of now, car sounds like something is broken inside and jamming the exhaust everytime I press the gas

I will try having my mechanic check the CEL and let you guys know. I can drive it but I think it's a bad idea since the smell is very foul.

 

I know this is a long shot, but if there's anyone who's expert on this matter and willing to come out and check the car out, I will appreciate for your time and buy you a dinner. I wish I can drive to a local autoshop and have the code scanned but I don't think it's a good idea to drive the car.

I'm located in Westminster area in socal. Thank you and have a great one.

did you check the oil for metal particles? what about the coolant?

what year SC? anything before 95/96 and you can check the codes yourself with a paperclip...

location may be a little different but the idea is the same.

 

if its not something bad internally to the engine, then I would look into the throttle position sensor or mass air flow sensor...

with the whole blue smoke, that makes me think you have a broken ringland or a dropped valve...

 

both of which are exceedingly rare on a 1uz

 

200k miles on the car... Are you willing to put money just to fix it? Or rather save up and get a lower mileage car? Just saying.
