Just bolt it up and be done with it its fine no need to try and fix

 

Watch a small piece of weld come off and take out the turbine

 

yeah that would suck super big ass! I'm in a rock and a hard place it seems. Fix it, or slap it on? I'm struggling to make a decision.

 

^this , if its shipping then it would have a dent
it looks like a heat fracture

 

all the lnf k04's do this. it's no big deal

 

I told you this was normal. I'll look for the tsb on it from gm

 

Send it back bro. If you're not happy with it, why would you keep it?

These things aren't difficult to find, so you can get another.

 

TX.SS.TC didnt even install it on his car >.< jus put it on your car, drive it for a lil bit an take it in under warrenty an see wat they say

 

im just going to throw mine on. i really dont care if theres a small crack on it. im sure if everyone pulled their turbos anyway thered probably be a small crack on half of them.

 

I think you can put it on, nothign should happen. i've seen this happen to evos and stuff too cause they have the twinschroll mani too. Shouldnt be a problem I've actually seen this happen on this forum too.

 

I have same crack on the turbo housing and my manifold mine look bigger than yours its nothing to sweat

 

X2..........that was most likely there before shipping

Me and Brian@BNR even talked about the dividers being cracked 3 weeks ago when I rode down with a Alabama Cobalt SS/TC owner to buy one, his had a crack in the stock K04.

My Stock K04 off my HHR SS I traded in on a BNR 2871GT with only 10K miles on it had a crack, no big deal.

 

Well, I'll slap it on then! No worries!

 

While I understand this crack is no big issue, please re-read your comment and ask yourself if it makes sense....

The crack is on the exhaust side big guy.

 

NP ....Glad to help!

 

Might want to read your own comment again

 

Yeah bro. Theres no way shipping caused that crack. If it did there would be proff before the crack of it hitting somthing. That was there before.....get ure money back.....

 

Even tho its a little crack. It can and will get larger with hot and cold. .. Once it cracks more the stress on the crack can cause it to break (peices or the whole damn thing.) dont install it spend ure money on somthing larger.. or better

 

James, all stock LNF turbo'd do this

 

Lol i know this i know the tsb. ( ill explain more. .... The dealership that i work with for doing aftermarket tunes came to me and said he theres a tsb for this car and we arent replacing the turbo, what do you think)....??? I said the same thing i did here. Later on about a year or a little less that crack became a larger crack which also warped and it caused bad exaust flow. The reason the car came ba k to the dealer was because its turbo fluttered un any boost. Put a new ko4 on it and it was gone. I am more or less saying it can happen ( safety first).... theres prob some stuff that caused it as well egts getting to hot. But who knows lol..

 

That's from the heat they do that

 

thats a heat stress crack in the divider there is no real easy way of fixing that and mine has two in it and i just put it back on it will be ok. the fix requires heating the housing with an oven and while its glowing cherry hot then you weld it up.
