msggunny Posted January 17, 2011 Share Posted January 17, 2011 This 2.25 petrol block i inherited has a hole in the partition between the water passages. Its kind of hard to tell from the picture but if you look closely just past and on the top corner of the casting plug you can see a black hole with silver blob sides. Everyone here i have asked cant seem to tell me if its benign or the making of a catastrophic overheating failure later down the road. Any ideas? Anyone seen something similar? Thanks. For reference, its the upper right passage coming from the water pump. Two different perspectives. You can see light through the hole when you put a torch on the closest water passage to it in the block. Quote Link to comment Share on other sites More sharing options...
Jeff Young Posted January 19, 2011 Share Posted January 19, 2011 What about using one of those epoxy fillers for repairing cast iron (JB Weld or the like)? Jeff. Quote Link to comment Share on other sites More sharing options...
Betsy Posted January 21, 2011 Share Posted January 21, 2011 I don't think it will cause any problems, because the the port takes water to the cylinder gallery area anyway, so a small hole between the two will not affect flow at all. Its all internal, so no water loss will occur. Quote Link to comment Share on other sites More sharing options...
