Offical: Porous Block Problem Thread
#227
So i have an 09 build date 09/2008. Ive had the car since it was brand new, it has 67k miles and has recently started exhibiting signs of slow coolant draining with no visible leaks or coolant in the oil. All signs are indicating that my block is failing. Only thing that is keeping me from thinking it is certain is the age and mileage, but i saw an example where some one had 80k miles before it happened.

Well I bought a 09 LNF sedan with 140k on it builddate 10/08. The coolant was a smidge low. when I got it. Like, we are talking maybe a cup if that. Let's see how it goes.

I have a 2009 SS LNF with a build date of 10/08 & 82K miles. Low coolant & coolant in the crank case just started Friday 1/22/2017. According to replies to the thread I started for answers to my questions I've got the porous block issue. I have the timing cover off & it sure appears to me that antifreeze is leaking out the water pump so I ordered a new one. I'll update this post if that does in fact fix it. But until then I wanted to post here.
I have read this whole thread & all threads here that show up under "porous block" in a search. I just have to say this... I have never been a GM fan. Until I bought this car I was always a Ford guy & had had a few different imports here & there. I bought this car because I got it extremely cheap with very low miles because it was a rebuilder & I knew the history of it since I knew the owner. I wanted a cheap, fast car with gas mileage. Until now, it has been an extremely reliable car. All cars have some little issues & common problems. But this type of thing is completely unacceptable. The stories of how the dealers & GM "customer service" have treated some of you is ridiculous. If the block happens to be my problem, I'm getting rid of the car & I'll never own anything made by GM again. I can accept some small issues a car may commonly have but this is a pretty big deal. It's something that's expensive to fix & from what I've read GM knows about it but doesn't care since they long ago got the money for it & have walked away.

I've got almost 100, 000 miles on mine and it's been pretty reliable.
Also people usually don't review positive experiences online. So there's a bias

You knowingly bought a rebuild. That's your problem. I work in the autobody trade and have seen the **** people do to rebuilt cars. Rebuilds are hack jobs 99% of the time.

on top of this, being a rebuild has nothing to do with a porous block.
gm did cover the problem under the 5/100 mile warranty, ive heard of special cases where they covered it even after the warranty was up. however the car is more than 8 years old now, you cant expect them to cover it.

My bias of not liking GM is based on my own experiences from previous cars I've owned & 25+ years of doing auto repairs for other people in my own shop.

ive done some rebuilds, all done 100%. most of the cars have been written off for minor damage or engine damage. where i am cars are written off for such little damage. its also not easy to do rebuilds, there are a number of inspections the cars have to go through and they have really tightened up the rules on it. so not all are crap.

Plus he's about to trade in his broken car to an unknowing dealer.

Yes more than likely I do plan to trade the car in. At this point even if it's fixed I might. And you're telling me that you're so morally virtuous that at no time in your life you got rid of a car because it had issues? You'd have to be extremely naive to think I'm the very first person to want to dump a car after a major issue reared its head.

Please explain to me where you see this? My post is relevant to the thread. Yours on the other hand is just trolling.

you spend 2 grand on a down payment for another car, or spend 2 grand to fix the cobalt and have a car with a new(er) engine that's paid off or closer to being paid off. I don't know your financial situation. im just coming from the mentality that id rather be car payment free and have a car with an engine that should be trouble free for at least another 5 years, than trade it in on another car and make payment for 5 years.
99% of people can't

someone posted a link to a "how to" in the thread I made during my situation. at first I followed it, but the swap really wasn't that complicated. and im sure if the person was respectful and asked questions, people on here would shed some light on any issues they were having.

I found the swap extremely easy. took me three days in my garage with no lift. Definitely doable for a person who has some mechanical skills.

alchargo. He kept the car and got a hold of an LHU to swap into it. Swap is done, cars making 25psi. His brakes are like new. Hes really happy with the car now.
i have an 09 SS sedan for 95,500 miles now and I have yet to see signs and symptoms of porus block yet. I noticed my coolant dropped last year maybe a cup (only a cup), but nothing else is showing any signs. I am thinking not all LNF engines went through this issue or at least I hope so.
