Overhauled a 656 gas, sleeves all pushed in equally smooth. Had it running maybe 5 minutes total playing with the timing and bam it locked up and killed itself but still would crank over afterwards. Pulled the oil pan to find chunks of sleeve in it, get the top end off and pull #6 sleeve and it has about 2 inches broke off the bottom.
What do you think caused this? Bad sleeve? Cracked it pressing in? Something in the block?
We are all scratching our heads here....
Thanks guys
