Yea motor is apparently done for according to the local shop here. I am def getting a second opinion though giving the fact that the motor does still turn over. I had issues starting to arise with the head which I believe was a bad valve. Now the sound has gotten worse, and the car has power loss. Getting car back tot he house tomorrow, and am going to have a look at it. The shop did not break down my car, nor did a leak down test ;|... all they did was listen to the sound of the car.. so I dont know.. I think blown head but they say different?..

 

do a wet compression and leak down test..
also see how much air is coming out of the breather tube wen u start the car...it will run funny wen u take the hose off while the engine is running..if u get a ton of air rushing out the hose i would bet u cracked a piston or more

 

Mm, okay ill def give it a try when I get the car back to the house.

 

Congrats bro. I remember my first LSJ

 

i remember my first 3 of them lol

 

Years ago I had a shop tell me my motor was done.
Didn'te even break down the motor to look.
All that was really wrong, was my oil pump chain broke.
New Oil pump chain and it was good to go again.

 

Would be pretty sad if your motor took a dump on it with only 50000 miles. Are you constantly beating on it? My intake valves were shot at 39000 km but that's because of di and you don't have to worry about that.

 

im at 60000 and i at least floor mine a few times daily. sometimes go for long pulls/races. wonder how long till i pop....

 

the lsj dosent have a oil pump chain the oil pump is greven by the crank through the dampner

 

LoL, dudes I am sorry I have not updated my sig, but now my car has 78,000 miles lmao so Rice be perpaired dude just saying Bahaha! , and ugh yeah I beat on it pretty hard man, and I am not mad it popped I had so much fun driving this car, and out running alot of cars I never would of imagined to be honest. I will get him fixed but will take some time, and it will be time used wisely. Really does suck tho lol because I am expecting a baby next year. I dont know gotta look around for either a replacement or maybe buy a new block fully assembled, not sure yet.. O and yeah I got the car back, and the rod is busted from the sounds of it, not 100% sure tho without breaking it down first..

 

I wouldnt say constantly, but every now, and agin I'll get on it.

 

Wow lmao I dont even know what to say bel, hahaha!

 

did you buy a new motor or rebuildor what?

 

lol **** happens if you need any parts lmk

 

Excellent man I appreciate it I am sure I will need something. Just not sure what I should do first Lol.. Got alot going on, and a bit overwhelmed lmao so I am sure I will be intouch.

 

You bent a rod with a 2.8 pully? Can that even happen? lol

 

mmm apparently? Im not 100% sure to be honest man. I dont even think its bent I think it is broke? atleast that was part of the info I was given from the shop. They started it up heard the loud clanking, and banging lol and shut the hood, and assume broken something lol so I assume broken rod?

 

Have someone experienced with Cobalts take a look at it, i'm sure you can find someone in Ohio. I highly doubt your motor is done especially when looking at your mod list.

 

yea I coud I suppose but it bangs loudly... I started it today and i think its something for sure on the bottom end.. ill have to look around and see whom i can find..

 

Get us a video.

 

I'm willing to bet money you didn't snap a rod in half... Where exactly are you at in Cbus?

 

North Columbus I have the parked right now out front of my parents. When I first started having issues dude the sounds were coming from the head. Over time it got worse..

 

Hmm.. I PM'ed ya.. I could possibly come out this weekend..

 

i would say spun rod bearing..
drain the oil and drop the pan.
and start tryin to move the rods

 

YEa talked to my unc about that. Tryin to figure if you can replace the bearing easly from their.. I would imagine you could but I wonder if any slivers got loose...?

But then again this a loud clunk rather then repetative ticking sounds at the bottom end...
