400 block problem
I removed my intake manifold to replace the leaking gasket and saw this hole at the end of my block right below the distributor. This is a reman'd block that is about 4 years old and has about 20,000 miles on it. The hole looks like something punched through it as it is not smooth. Anyone know what this could be from or if it is causing problems? I had a timing chain break on this engine and am wondering if that caused the hole. Please help!
