I think ive found a tiny hairline crack in my rear iron when I was searching for the source of a oil leak.

The oil isnt coming from around the crack, and its near where the motor mount is bolted in.

Anyway, heres a pic, let me know what you think.

 

nvm...

 

poor picture, is it running down the center of the stud for the engine mount? if so, can't really suggest anything except just keep an eye on it and see if it gets worse. cast iron isn't really a repairable meterial with any decent capacity.

 

Yeah. Its tough to get a camera in there to take a picture. But it is coming off the engine mount stud.

 

can't suggest anything aside from that doesn't really look like a crack to me.

 

Hmm. I'll see if I can get a better picture of it then! It feels like one to me if I run my fingernail across it. Im just wondering if I tightened down the engine mount bolt too much...

 

if it is then i doubt it, it's probably more or less a stress crack from the FD mounts coming across so far to attach to the FC subframe.
