Enough to drip about 1-2 oz on the ground when i took the intake tube off.

Dealer called, turbo bearings are shot and the exhaust manifold is cracked.

 

$700? Did you buy the zzp stock turbo and have them install it? Good deal then. Ive been on 24 psi for over 2 years now. no problems yet. 24 psi seems okay, I think there are just some turbos out there (a very small number) that are just bound to blow no matter what.

 

Nope, family friend is the service manager. New gm k04 and exhaust mani installed for 700. All parts ordered by the dealer

 

Got it back. Gonna go easy on it for awhile

 

damn for that price I'd rather buy an S20G

 

Isnt that like a couple grand? This was with the new turbo and all parts included in that price. I paid no more than that price for parts and labor

 

Yeah i guess with instal that is decent.

the s20g is 989 IIRC. but you need a BOV

 

I priced it at like 2 grand

Quick observation, did about 2 pulls with my base tune and the turbo boosted to 22 twice. The failing turbo boosted to 24, is it possible the old turbo with bad seals and bearing required more boost to make the same amount of power?

 

Or a t3 mani

 

Why in the world did you get a new exhaust manifold? You could've saved yourself an extra $200 right there.

I had to, generally a cracked exhaust manifold isnt usuable anymore. Dude I paid 700 for everything installed. You cant even get the turbo from GM for that.

 

You never once stated it was cracked. You confirmed it was a blown turbo. Still don't understand how you cracked the manifold.

It was probably the standard crack in the exhaust manifold

 

Yes i did, go back a page(if your own mobile) and read my reply to leemanfor about excess oil. I clearly state "bearings are shot, exhaust manifold is cracked"

Reading > You

Not exactly sure didnt see it, but on the turbo side, right where it connects to the exhaust mani, there is a splitter in the center of the pipe kind of like an S. That had a crack right through the middle of it. Tech said the exhaust mani had a crack from inside to out. Didnt get to take the blown turbo

 

Yup thats the standard crack, a lot of ppl have those, doesnt really effect performance from my understanding.

 

What causes that? According to the tech, the exhaust mani had a separate crack. I dont mind, my payment amount didnt change before or after they told me the mani was cracked

 

yeah you got fucked if that was the crack, 100 bucks says your current manifold will have it too after a bit. it doesn't hurt anything.

 

we all got that crack.

 

not sure what causes it to crack but its not a big deal for the operation of the car. I think all the turbo cobalts have that crack. I havent even looked at mine and im certain its there. Not a big deal. The new one will crack too. Im sure the service guy didnt realize they all get that crack. he just knows it didnt come from factory that way.

 

Meh, i don't think so. Remember my qoute from my fam friend was 700 before they even got the car. Nothing changed when they found the cracks in the turbo n exhaust mani
Thats what im hearing

Yeah but not a big deal to me. The manifolds were essentially free. Bad design? Overheating?

 

considering new turbos from GM are more than what you paid for both + install you didn't get screwed, but now when a tech tells you the manifold is cracked in the middle where it "scrolls" the exhaust to the turbo you know its a ok!

 

Thanks! Im curious about the crack in the exhaust mani though. I didnt get to see that one

 

here you go OP.

Normal Turbo Cracks - Pontiac Solstice Forum

its for the turbo, but the matched exhaust manifold does the same thing.

 

Wow. Normal lol Im beginning to think that a blown engine would be normal to GM

 

I bought a new K04 from the Classifieds for $250 back when everyone was ditching their stock turbos. Keep an eye out and buy one just to have an extra. I haven't needed it, yet, but I'm on a 21 psi tune.
