Cylinder Casting

[Clark6]

can someone give some i put I may have missed it over the years but up in the underside of the block is this webbing possibly cylinder casting or is the cylinder walls coming apart? I only see it up in all the passenger side cylinder wall & driver side #1

Looks like casting artifact. A crack would be much more defined and start at a stress riser like sharp bend in the casting surface or near a main cap bolt hole.

Thanks Inky that's comforting to know!!

All of them have it except 3 & 5 but Cylinder 4 is the worst one.

The right side of that looks suspicious. Get more light on that spot. It's probably just a shadow caused by that casting flash line that starts in the middled.

This is one of a million reasons to deburr/deflash a block when you have a motor apart. Cut down flash and then when you do inspections later with an inspection camera you reduce scary things that end up being shadows or bad lighting.

Inky My Guy You were correct again! I have a cheap endoscope with a lighted camera & it's just as you said... it's a solid drizzle all of them. It's like when we use RIGHT Stuff or silicone, or rtv & it keeps coming or drizzling out the nozzle even when you're finished. It's like that but metal. Whew! Dodged a bullet.
