    Default Cracked Block: Oil Return Drain

    Folks, looking closely at the oil return drain, 4AGE 7 rib, noticed a bit of a crack. At least I think it's a crack, could just be the way they're made. If it is a crack it doesn't look like it's going to be problematic, fingers crossed!

    Comments?



    Cheers.

    Seems an odd place for a crack to form.. Maybe the metal didn't come together properly during casting? Who knows..

    not a crack, that's part of the casting process where the metal from either side of the mould has joined together.

    DNeg, BlackFox, Sam, thanks. Couldn't make my mind up whether it was a crack, and therefore a potential problem, or not. Think I'll put it down to poor QC and ignore it.

    Cheers.

    I checked and both of my open 20V blocks don't have this, does it go all the way through the rib?

    The "defect" extends for the length of the "join" in the top of the oil drain. It doesn't extend any further into the block, that's why I'm not too worried about it.

    Cheers.

    I'm inclined to that opinion myself. 7 rib.
