Metal cracks on engine blocks
 

Hey guys, it looks like there are cracks on my engine block, they are all over the engine. Was wondering if it's normal. It's a 2017 brz

Not cracks at all, just texture left from the casting process.

casting flash or maybe mold release agent related
Nothing to be worried about


Any casting experts here?

Sorry to see that ...... one more freeze thaw cycle and the block will completely disintegrate ......:sigh:

I'd sell it immediately and stick the next buyer with the problem. Just to help out, I'll give you $2000 for your car.

Did it for a few months back in 83. Worst job ever.

You guys nailed it though. Other than the release agent theory since they are sand cast.

Good video here.
