Major Problems Help!!!!!

i changed my headgasket... and put everything back together.. re did the timing...

started it up and sounded normal... was letting her warm up and about a minute or 2 later... i hear a loud BANG and a super loud metal to metal sound... then the motor just died down and shut off


now it will barely turn on and once it starts it will die rite away..


ANY IDEAS!!!!!!!????? i'm at a loss rite now i have no clue what to do..?

Have you done a physical inspection of the motor to see if you threw a rod or something through the block? Look around the front and rear of the lower half of the block. Make sure to look BEHIND the exaust manifold because it could be hiding something. Your going to be looking for a hole of some sort and metal chunks. Also, what does your engine sound like when you try to crank it. Don't go and try to crank it again because that could do futher damage. Just a more detailed description of what you heard. I know this sounds obvious as well but did you drain the oil when you changed the head, and if so did you remember to replace it?

i did not drain the oil before replacing the headgasket... so i know it had oil..

and when the motor died.. it just made a LOUD METAL TO METAL BANG

and no havent tore down the motor to check what is wrong yet... i know it's fucked up.... cause it wont turn on anymore...

im just too pissed 2 fuck wit it... i ordered a b20 long block

What's the info for your car? (year, model ect.)

95 acura integra ls... with 92 b16a motor....

Have you been running it hard? What I meant by a phsical inspection is just simply a visual once over to make sure there aren't any holes or anything in your block.

maybe timing belt was too loose and it jumped and bent your valves which is why its not starting anymore. but i dont think it would be a loud bang.

i would recommend check the timing putting everything to tdc and check timing. then pull the oil pan and inspect the rods and bearings for play or scoring or heat marks on anything. also check the oil pick up and see if anything is on it

i know you dont want to but tear her apart thats the only way you will know for sure .. besides its not run might as well
