Have you had the car looked at by gm ? And if so are ghey replacing the engine. Or are you assuning you have a porus block because the low coolanf light coming on a few times ? That is a fair amount of miles. I always figured a porous block would cause problems well before 80,000.

A lot of the block material, especially the oil filter cap area, looks like aluminum styrofoam based on the texture. Just an observation...
My contribution to the thread is that I test drove several early 2009 SS/TCs, one of which was at the dealer with less than 100 miles and the LOW COOLANT message was displayed. The salesperson told me not to drive too far with it and turn around. This was a brand new car BTW.

i havent had them replace anything, and per the previous owners records in the owners manual the only thing replaced so far was an exploded pressure plate i think? it was something odd with the transmission..

Oh ok... I get it. You were just saying based on your build date and having saw the low coolant once or twice you were thinking MAYBE a bad block ?
It's funny , because before I bought my 09 TC a year ago I had an 06 ss (lsj ) for 5 years. And every other month I had to add a little coolant to it. It had no leaks. Wasn't in the oil. But about once every 3 or 4 months I had to add a little coolant. But the car ran great and I never thought much of it.

Flush the coolant system with straight water. When all the gm coolant is flushed out add a bottle of Moroso Aluminum block seal and run it for a couple days. That should seal any pores and hairline cracks. .Finally drain water and add antifreeze mix. Did this with 2 porous blocks and worked on both.

I believe I have a cracked/porous block. Had low coolant, temp went up, brought it into dealer and they replaced the head gasket. Drove it home today and same thing occurred. Do you think this is a porous block issue???

My ZZP gen 2 block ended up being a porus block, but that's the exact reason they stopped warrantying them tho. I took the risk and got the bad end of it. Nothing ZZP did tho, they stated loud and clear on there website it could happen. Also not on them but it started as soon as I put the new motor in so I am guessing that's why the owner of the block the last time swapped it out, which is shitty on there part and wouldn't mind talking to them at some point lol, ok, end of post lol.
