Have a diferent post trying to figure out why my oil and coolant mixed and if any damage was done to the engine. My question is do these d15 blocks crack very easily? And if so how can you tell?

No, they are bomb proof.  Being aluminium, it's easy to screw up the head bolt tightening, sequence, etc.

It's probably the head gasket, best to pull the head and take a look, also check for bent valves, and chips in the pistons, Dave
