Even resleeving with stock sleeves can cause things to crack. This has already happened to a few members on here. It requires some exact and knowledgeable machining.

 

Went ahead and pulled the motor the other day.

 

So looking at these pictures, I assume you dropped the motor with the sub frame, removed the crash bar (and the other jazz there) and slid the motor out the front sideways while lifting the front end up slightly?

 

The crash bar is still installed in both pictures, but it looks like the rest of what you said is right. out the bottom then forward.

 

^^Yeah I thought *maybe* he put it back on then took the pics...

 

If the head is still on then you need to remove the crash bar. With the head off you can get enough clearance without removing it.

 

good **** man. think you'll be able to lay some times down before the end of the season?

 

Oh okay. I see. Thanks for the info. I always find this stuff intriguing.

 

So does zzP consider a block with a cracked sleeve a core I also just blew a sleeve and in the process of getting money together to get a shortblock

 

No it is no longer able to be a core.

 

Not sure. If I could get my lights sold and what not maybe. I don't know if I should just wait and do it over the winter and do the 2.1 and electric water pump and all the goodies.

 

Dam good luck man that looks like a nightmare. How the heck you remember where everything goes perfectly lol. I'm nervous swapping my trans out that I'm gonna forget somethin.

 

I have done it a couple times lol.

 

Subd for a always good show and good luck

 

crazy with the motor out n all..

 

Good luck my man!

 

good to know..

a cracked block becomes a ecotec paper weight.. or sell it to the junk metal shop - i think aluminum is now at 70 or 80 cent a lb.. the place near me is at 76 cent a lb..

i've pulled out a couple already at the shop..PITA

 

Holy Crap. GL man

 

Pulled the motor apart. Crank, pistons, and rods are all good, no wear on the the bearings at all. Might end up having to sell the pistons to get 86.5's since zzp uses the 86.5's on the lsj's.

 

wow in for the rest of the build....I want to see how crazy ur Cobalt will get....nice

 

OUCH...sorry to hear about the sleeve. At least you know what you are going to do next and can get it done

Good luck man. All the best!

 

can you post your build sheet again? or even your new updated build sheet?

 

if u rebuild ur motor but is the break in time ur looking at? i was reading ZZP short block becuz thats the options im goin with and it seems to be a pretty lengthily break in period unless u do continuous driving.

 

You should really give it some time when breaking in an engine. How ever I drove the car easy for about 50 miles. started giving it some mid throttle pulls to like 4500 and let off a few times, drive the car for awhile then do it again at a higer rpm. One of the big things are heat cycles with the motor to get everything seated good. About 500 miles is what I have always heard.

 

Before it was simple lol. Stock motor, k1 rods, wiseco pistons, zzp cams, supertech springs, and zzp balance shafts. Now I just have to think if I want to get it done on a budget or wait through the winter to go a little more indepth.
