Has anyone every heard of small block cylinder wall damage due to water pump or timing cover bolts that are too long? I've seen a couple of references to this over the years, and didn't think much about it.
I just freshened up my 318 after years of not running - new gaskets, timing chain, water pump, fuel pump, etc. When it warms up, it has a mild "squawking" sound which seems to match the crankshaft speed. I've checked some of the obvious things (belts and accessories, torque converter and flex plate) but everything seems okay. I've used a stethoscope, but can't seem to trace it to any particular location.
Looking at it, I can't tell which bolts would actually line up with the cylinder. Is it even possible? Writing this down, it sounds crazy.
Your thoughts and advice are appreciated.
