Hi guys,
I am rebuilding my 340 and found a crack on each side of the block. The area looks quite strange to me since I could not find any pic on the internet where another block looks like mine. It looks a bit like some sort of plug but I am sure it is not. Can anyone explain what it is and how serious the crack in this area really is? Is the oil galley behind it or a water jacket?
Data:
LA 340
Casting Number 2760930-340-4
Built 6/22/67 (nightshift)
Engine was running before tear down, no smoke or other indicator for burned oil or water. No noticeable amount of oil in water (but a huge amount of rust in water channels and jacket)
Thanks a lot for your help!
Chris
