I was putting ARP headstuds in my A6 block i guess i didn't get all the coolant/oil out of the hole and when i was torqueing down the studs(only to 15 to 20 pounds) i seen coolent seep out a hair line crack straight down,right at the bottom of the bolt hole on the outside of the block.Know do you guys think its ok.Has anyone else had this happen.I don't think it cracked through the block but i don't know.And another thing do all the studs suppose to be the same height because one of them if your looking at the motor in the car the top left one on the dizzy side is higher than the rest.TIA BTW its A6/Z6 mini me

 

It's normal for the top left one to stick up. It's made to do that.

A pic would help to see if it's cracked.

 

Never posted pics before not sure how to do it,lol.But you can't see any crack i just seen a little seeping from a spot the lenght of a thorn(you know from like a bush,lol) or smaller,seen like three or four little air bubbles its the second to last on the bottom right at the bottm where the bolt would bottm out i guess but on the outside

 

Sounds like you got some air and coolant in the threads. BTW: coolant doesn't compress, it's a liquid. Therefore it had to get out somewhere, and made a crack.

 

Soooo you think its alright?

It is physically possible to compress liquids But in this case there was most definitely not enough pressure to accomplish it.

Whats the worst you think could happen?Maybe start overheating?Don't want to screw me head up,it's getting cleaned,milled pressure checked.
