Okay guys who have had their engines go, did they sound like someone swapped in a diesel engine??? And nothing above 4K rpms.
The sad thing is this car had all the cooling mods done already.

 

Wasnt this another SS/SC you had?

What other symptoms do you have?

 

RIP Cobalt

 

Oh ****! That's not good! Is it a blown headgasket possibly? I see I have a PM, so I think I need to go check it.

 

No power and she sounds like it had the diesel swap. Oil light is on but there is plenty of oil.
It will be resurrected but I would have preffered not spending the $$$$$
That was me

 

Dang....

Hope it gets better for you!

 

Ok, PM sent back. I need some more details. When you say sounds like a diesel, is it knocking or is it sputtering and billowing out white coolant smoke? Did you pull the plugs yet?

 

so.....about that "awesome" tune you were telling me about......

check the oil for coolant

check the coolant for oil (it'll be dirt nasty black)

pull the plugs, that'll give you your answer.

looks like you get to re-build two cobalts.

you should have plenty of stock parts sittin around to use!

 

Me too but to be safe, I won't be crossing any streets today

 

sry to hear

 

Just got back home. I think a nap will happen before I rip into it
The oil is as clean as brand new. No coolant, no foam, no sludge.
I haven't really got the time to rebuild. I will likely order another and build this one later.

 

so its all clean....

any smell or smoke out the exhaust?

 

You are ordering a 3rd Cobalt??

 

I can't blame you on the nap thing, but I certainly would like to know what went wrong as I'm sure you do as well. Make sure you go get a cup first because the wifey is probably going to kick you in the nuts!

 

Geez Victory, order up a new motor... where the heck do you work, or what do you own! LoL!

Best of luck bud, you are Mr.Cobalt thats for sure.. LoL

 

No smell/smoke/water.
It all seems normal.

The wife would kill me for a 3rd Cobalt even a 3rd engine but the engine will likely be what I order.

I want to know too but when things go wrong, I find a nap prepares me for the worst. I am getting my cup on as I type. The wife just got out of bed. Maybe I need to just do her first, to make her all giddy



Other symptoms.

Oil light on, battery light on and the serpentine belt not spinning at all. The belt is tight and turns by hand with normal pressure.

 

sorry to hear about that man.. give me some more info and i maybe able to diagnose the problem... and if im not mistaken.. you havent pulled the plugs yet right?


EDIT>.. i see you selling a spare engine in a few months/weeks

 

hmmmm i wonder if we are going thru the same problem.

actually i think yours is worse than man.

 

You think the blower could have locked up? Matty did say that his previous blower failed in a similar fashion if I remember correctly. You might just be in luck! I'll keep my fingers crossed for you!

 

the belt doesn't turn when the cars on?

huh?

when dans blower took a dive, the same happened.

i think i have a blower "around" if need be.

ya dig?

 

Thanks. As for how do I afford this, I am cheap and don't spend money on anything else, except the wife.

If I have a spare, I will likey keep it just in case. Then again, the wife will likely wonder why 2 spare engines are sitting in the garage.
I will pull the plugs after my nap.

I feel for you too. I hope it's not too bad for you.
The S/C pulley spins, no problem. I will talk to Matty when he gets up as he works afternoons.


One other thing that has been happening which Matty thought were the Iridium plugs, it would idle rough. Over the last couple of days the idle got worse to the point of hesitiating when taking off from a stop.

Okay, so if the blower took a dump, and the belt doesn't turn, the oil won't flow which would cause the knocking.
But why would I be able to spin the pulley by hand with no trouble?

As for that spare S/C I call dibs, just in case.

 

****, not the blower then eh? I hate Iridium plugs, and that's why I went back to the good old $2.00 NGK ones.

I'm running out of guess and all the signs are pointing to #4 here. Damn it this really sucks for you.

edit:

If the screws locked together and then broke the gears or snapped something, the pulley might spin afterwards. Just a possibility.

 

Rod, i'll get back in on this and back with you in a hour or so, more meetings to attend......

 

I was going to change out the plugs on the weekend because Matty said you weren't happy with them and I was getting annoyed with them as well.

I guess it is nap time and then time to get up and remove the plugs, then S/C and then the head. Yippee. I guess that means I have to clean the garage first to get in out of the rain. More Yippee.

 

Rod, I really feel bad for you. (no homo) Maybe you can get the wifey to have some "happy time" with you before the nap, and then work on the car later. Don't tell her it's blown until you know for sure. If it is the supercharger though, now would be a good time for that TVS without getting you into trouble!
