Possible cracked block?? HELP!!! 5M

[Mitch1jz]

Before I go and buy new headbolts and spend un needed money I need to know If my block is cracked. After pulling the head I noticed the cylinder bolt hole was full of oil. I cant upload pictures till I get home. But the thing is full of oil. Is this bad? I drained the oil to.

That doesn't indicate anything. A lot of oil get hung ip in various areas of the block and engine even when drained... hence the two different specs for "dry capacity" and "oil change capacity". It's not the easiest thing to check for if you're looking for a hairline fracture... Pour in UV dye, thread in a headbolt with teflon tape around the threads to prevent the dye from escaping through the top and tighten the bolt as much as you can (keep under the regular torque spec though).... let it sit for an hour and then use a blacklight to see if anything.

But really it's wasted effort; Oil isn't going to get in a fill a hole which was populated by a bolt... there's no room for the oil and it's too thick to press through a hairline fracture at even double the system's normal operating pressure.
