Hi Folks, I had send an email to Chevrolet about 08-10 Cobalt SS/TC porous block issues. I have build date on my car 09/08. I am at 68 thousand miles right now and haven't get low coolant yet but I know I will be if I putting more miles on my car. This engine for this car is too fragile waiting for it to crack. I had seen so many owners of 08-10 Cobalt SS/TC had paid thousands of dollars to have their engine replaced. I don't agree that who is the owners of this 08-10 Cobalt SS/TC should be paying thousands of dollars for general motor manufacture engineer's flaws that they knew about porous block. I had contacted The Schmidt Firm about related to this car porous block that should be recalled. I even send them a link directly to porous block thread.

 

I don't think I see them taking care of it as a recall but I could be wrong

 

Hope this works out to solve this problem

 

"Haven't gotten it yet but I know I will"

No you don't lol. If it was as common as you think then there would be a lot more people complaining. There are tons of high milage lnf's. Not against what you're doing but it's less common than what most people think

 

It's not complaining. It's a concern if it does happen then it will be a complaint. I get what you are saying here. However, I support Cobalt community who had suffered paying thousands of dollars for their porous blocks. If it happened to you and you just got a car without warranty then you're fucked with the loan. Just like this ******* did in another thread lying to dealership. He got out of it from his porous block and got a new ride for his wife.

 

GM has bigger issues then the porous block...

 

I'm at 73,000 miles. Not really worried about it, but it's always in the back of my head. I'm a full time student and I work full time. I don't have the time and especially not thousands of dollars to fix it if it happened. I'd have to park it (while paying for it) and do nothing till I can fix it.

 

I didn't think porous block was still an issue for the 2010s. Well that sucks.

 

I was this close to make a real with 2012 Buick Regal GS Diamond Tri Coat 6 speed manual. DAMN! This car is very nice car to have!

 

I just turned 74k myself with a build date of 12/08 on my sedan. I have basic bolt ons and quite a bit of track time on the car. I'm not worried about it, but it's in the back of my mind. I figure since I made it this far abusing it, it's hopefully fine.

 

I don't really abuse my car. I mean every now and then I like to do some pulls or something, but I have never tracked it. It is stock engine wise. The porous block is more rare than people make it out to be though. If it were to fail on me, I'd be driving around an old Monte Carlo until I can pay for a fix. Which would be a while since school is in. Sucks the car isn't paid off, but oh well. I'm young and doing my best lol

 

I do agree on some level, But if that was the case...

Personally I think the timing chain tensioner should be recalled and upgraded to the new style.....esp cuz this problem isn't model or engine specific.....Just my 2 cents


But good luck man

 

most of the cases ive seen are guys getting the porus block before or around 30k, me i had my porus block issue at 19k and that was all but brand new. Dealership covered it too. yes it can happen at anytime but with higher mileage lnfs you shouldnt be worried i mean hell, you shouldnt be worried because a motor can go at anytime no matter what. if your biggest issue is the porus block then dont worry about it anymore man, youll be fine.

 

Yep, 74k miles with a build date of 12/08. I have basic bolt-ons and 23psi tune along with a slew of road course track miles. I have abused the hell out of that engine. I'm assuming all is well and I'm not worrying. I've had a handful of lab analysis done on my oil and there's been nothing to suggest otherwise.

 

youll be fine man lol keep doing what your doing lol honestly im at 88k right now so ive got 68k on the new motor and have yet to have any issues. knock on wood. getting up there in mileage as long as you take care of your stuff youll fine. clean the valves and do regular oil changes as well as plugs there will be nothing to worry about

 

Mine happened at 72k. Who knows how many cars it has happened/will happen to? GM's too worried about their cars killing people right now. Even if there were some sort of legal recourse, the bailout removes any liability from GM for the majority of us. I'm sucking it up and moving on. I've learned my lesson.

 

I found this at HHR forums and it's an LNF. Here's the proof!

 

That's talking about the cylinder head, not the block. Just something else that could be bad.

My dealer refused to elaborate on their diagnosis, but they were very sure I needed a new short block. Also, this wouldn't cause coolant to pour into the oil pan unless the head damage were in between a coolant and oil passage. Damage near the cylinder on the head would just cause it to pool in the cylinder, like the TSB is suggesting.

 

AH Crap! (Smacked My Head)
