Hidden c5 coolant leak
I’ve been searching high and low for this coolant leak I have on my 2001 c5 corvette it’s coming from the drivers side right behind the wheel and leaking down the middle of the block there doesn’t seem to be any way that coolant could get there in my mind I’ve changed the head gasket 4 times now and I’m just starting to give up anyone out there that’s had the same problem?
It’s a 2001 c5 corvette with a 5.7 ls1 with a btr stage 3 cam

Try checking the block plug on that side. Should be a giant Allen head (17mm I believe). Seems rare that that would be the case. Is it running down the front middle or rear of the engine?
When you did the heads, did you make sure that all debris was clear of the threads and torqued the heads to spec?
You can also use a mirror and look for the leak while running they sell little inspection mirrors that’ll make a world of difference with this big engine in a bit of a cramped engine bay. GL you got this

it’s running down more tward the rear of the block and yes I scraped the surface and cleaned the bolts also put lock tight on all the head bolts they are torqued to spec as well ////////// if the heads weren’t torqued right wouldent it have coolant in the oil ? Or leaking oil as well it doesn’t appear to have either of those problems or would it still only leak coolant ???
