ok before i begin i want all of you to know that i already know how god damn stupid this was, you dont have to remind me, you dont have to make fun of me and i will already go and call myself a dumb ignorant fuck. now that thats out of the way heres whats up. i tore down my l20b today to get it ready for hot tanking and decking tomorrow i got it almost apart and i went to remove the freeze plug on the front of the block behind the timing chain, i didnt have any trouble on the other freeze plugs but because the #1 cylinder was so close i couldnt get any vice grips on the plug to pull it out, so i decided to use a slide hammer. using the slide hammer required me to use a drill and drill a hole in the plug to get the screw in. well long story short the freeze plug was backed up against the cylinder wall and i didnt feel when i drilled through and began drilling into the cylinder wall, well it didnt look to deep at first and it wasnt all the way through so i contined to take out the crank and the pistons, now upon inspecting the bore you can barely feel where the metal is pushed in towards the inside of the cylinder where i was drilling, it did not go all the way through but i am sure it is very thin there, now i have an l20b that didnt need any boring or cylinder work and just needed cleaned and reassembled. HERE IS MY QUESTION what are my options? here are a few i thought about
1 getting new block
2 welding up hole and remachining number one bore to spec
3 sleeving number one bore
4 sleeving all bores
5 welding up hole and overboring every cylinder
6 sleeving all bores with oversized sleeves
7 weld it up, hone it out a bit to knock the high spot down and say FUCK IT
8 definitely never ever do this again
well boys i need the best advice you can give me, im on a budget so i need to keep the machine work to a minimum, i have standard size pistons with new rings so if i could keep the bore standard it would save me money on buying pistons. and once again i know im a retard.
