sheared flywheel?

[AceGAGT]

so i finally figured out that there's a bleed screw on the clutch master cylinder. so i got that all bled and drove my car today :D. made it to rippey 6 miles away. filled up with fresh gas. made it almost home and all of a sudden i had no power at the wheels. it idled just fine. so i coasted up the road almost to the shop. didn't quite make it tho. turned it off n went n got my dad to help me push it. got back n it wouldn't start. so we pushed it into the shop n jacked it up. i can turn the wheels w the flywheel. i can turn the flywheel w the started. but it doesnt turn the motor over. so we believe that i have managed to shear the bolts off in the flywheel. hopefully it didnt fuck up the crankshaft. has this ever happened to anyone else before? and is there anything specific i should b doing when i put it back together? o ya, and when u hold a wheel n spin the other one u can hear someting metal clinking around like its falling in the clutch area. clutch is fine also. grrrrrr after $2500 and 2.5 months of tinkering and painting......

yso it turns out we were right. sheared the bolts off. apparently i must notve gotten them tight enough. also the vibrations from the motor and coasting cause it to wear the inside edge of the flywheel, and surprise, surprise it fucked up the end of the crankshaft too. i can move my other flywheel bout half a mm in any direction. great. so i get to tear apart the lower end of the motor, remove the balance shafts, and replace the crankshaft. and go over every bolt i can reach twice more to ensure theyre tight.

ok so this may be a dumb question but i want the answer anyway. how different are the 99-02 ld9's from a 96? like especially the main journal bearing bolts/studs? the 96 has 11mm torque-to-yield bolts w 1.5 thread pitch and they r 3.13 inches long... sry dont have a metric vernier caliper that i know of. gm does not offer them for the 96-98 anymore. and the parts houses cant find a part number... unless maybe o'reilly's does... f that tho.

ok so its finally done. 140 miles on one tank of gas, might get 40 more... kinda shitty. itll get better. swapped the cams from the '95 2.3l. i definitely the low end torque. but at about 4k it really picks up. finally shut my lil brother up about it. hes been raggin on my car but mostly on the motor. cause "its a fuckin quad 4" ya well from a dead stop he had a car length on me in his 2002 police interceptor when i hit my limiter. hes not making fun of it much now. my dad quit raggin on it when i finally started gettin it put together the first time. hes not a big fan of the timing chain set up. and i cant argue w that much but my lil bikes got chain timing and it works great so.. w.e. no more mufflers. they were rotting anyway. now its quieter in the car itself but it sounds better (i think) outside. i put the stock tips back on tho lol and im still fightin the driver side one to get it to line up correctly...

has anyone ever had problems w the motor after a cam swap? at around 2500 rpm cruisin down the road it shugs. likes its misfiring either an injector or plug. let off the throttle and it stops when u push on it again. put it on the floor n it kinda putt putts a second or less then picks it back up n goes. but its a noticeable delay. my bike does it when its still cold at WOT. put MTF in the cylinders when i had it back upright to lube the pistons. thats all over the back of my car now. but could the plugs just b dirty? i dont have the tools to pull them now that im back in dm. ill go borrow some from advance across teh street this week but id like to get some opinions?

o and my car wont turn the reverse lights on. the lights r good tho. could that be related to the ground problem w the speedometer? except that something is gettin a signal. the ODO works. kinda at a loss about this. dont have the money for a FSM set... dont have the money for anything except maybe insurance and a tank of gas... thanks in advance for any and all help and opinions
