Ok so heres whats going on. I noticed my coolent light was on two days ago and thought it was just a false light because i have had that before. Today im driving to work and I look at my dash and the light is on again but this time I check my Engine temp and its started to go up. The temp climbs up to about 235 when i shut off the car and coast into work. I look and there is no coolent in the overflow tank at all. So i go and fill it up and drive it for about twenty minutes and its emptying again. I dont smell anything burning off my engine and i cant see any leaks anywhere. I read a thred on the Porous Block problem and so I checked my oil and well lets just say it was pretty milky. I also noticed that my ehaust was lighter in color and more visible so im not sure if thats oil buring or something maybe water. Anyone have any ideas im thinking either Headgasket blown, Bad oil and a coolent leak I havent found yet or worse case senario I have a cracked block.

What do you guys think?

Also I still have full warrenty soo in your opinion what do I need to take off to get my car covered. I dont have my stock Intercooler anymore or my stock Exhaust. I already detuned it today.

Thanks for the help

 

Id say you have a porous block.

 

Do 2008's just now show up with a porous block after 3 yrs? Wonder how many else will start leaking in the future if so?

 

Could be the head gasket but I doubt it, the head gasket is very durable in these cars and 08's have been known to have porous block issues.

 

I thought it was just the early '09s. Ugh............I have an '08.

 

this is what happened to me and i had a porus block, could be something wrong with the head though

 

it seems as though when GM started laying off people and cutting hours their quality when down. i have not heard any problems on early 08s but the later 08s and 09s seem to have problems

 

would look into the head gasket.

 

Thank God. Mine is a first-run '08.

 

what the heck is with these engine, why have so many of us has porus block?

 

Thanks for the feedback guys shes getting demoded this week and heading to the dealer soo hopefully they dont give me **** for my exhaust if they do GM will be getting a Lengthy phone call/letter

 

check the coolant line going to the turbo. Mine was leaking bad. went to oreillys and got some heater hose and fixed the problem. total cost was around 7 bucks for new clamps and hose

 

Ok yea ill check it but i doubt thats it since I have milky looking oil

 

Damn that sucks. I was loosing alot of coolant and it was that hose

 

had the exact same thing happen to me... it was a porous block.. have the dealer check it.. im pretty confident that is the problem.. if it was a head gasket you'd probably have a huge white cloud following you around and the smell similiar to antifreeze/maple syrup when you turn your fans on.
