hi folks, long story short. and i think i know the answer(a different block), just don't want to hear it. <br />just went out to start cleanin up the block on my il6 chevy 250, 1972... heads off bein repaired. looks like i'm doing things backwards as i just descovered i got a crack on the block. port side, front screwhole. right by the waterpump. think it'd be the #13 bolt. no water leaks externally or internally that i'm awhere of... oil is clean.<br />so did i freeze damage it? where does freeze damage show up at usually on a il6. not like it makes any difference. i winterized dry. drained block, manifold and riser and removed waterpump hose at bottom. so felt i had a pretty dry block. anyways...live and learn i guess..<br />the crack is visable right down the screwthreads. 2 cracks, 45* apart, cracks leadin to front and port side. i can't think very seriously that i'd ever get a bolt to torque up to 90 ft lbs without breakin the corner of the block off or just pullin the screwthreads right out of it...<br /><br />any advise? am i hopeless? i guess money can repair anything, but i aint got a lot... i can't even think that a good Machinist could be ontoit(gonna ask one though) as the crack is inside the screw hole leading outward. surface of block(deck) shows the crack too. the surface of the block on the outside, ft and port side show no eveidence of a crack. well, right at the very top front of the block, 1/32 showin on the front, maybe.. crack is all the way down the screwthreads, visiable... what me next best step..... ![Frown :( :(](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
