So I figured out why the engine doesn't work...

I bought this car with the motor like this, I was planning to do a 6 bolt swap, then thought about fixing the motor but I guess I have no choice but to do the swap. what do you guys think, Spun Rod bearing?

Unless there was some friction causing the rod bearing to be tossed from it's location, I would say definitely not.

It looks like you might have thrown a rod, though. Or maybe your connecting rod snapped... many things. Plus, I can only tell that it's on the bottom side of your engine, due to the location of your catalytic.

Thats not a cat, its a Flex pipe, cat is behind it. Its the oil pan, and no trust me, i spun a rod bearing. Its a dsm 7 bolt motor, and they are notorious for doing that, mitsubishi effed up BIG TIME on the 7 bolts. for lack of a better word, my car Crankwalked..

I have had a bearing spin on a 302 Windsor and a 350 Chev which causes a very distinctive knock but only an idiot would continue to drive it until it threw the rod (assuming its a rod bearing that spun), but its a possibility. I have also stripped an 305 engine that the rod cap had broke off and had put a hole in the sump very similar to the photos above, checking the bearing it also looked like it had been spun and someone must have driven like that for awhile because it was very chewed out. The rod was also bent and the piston got jammed in a odd way that broke the piston skirt and cracked the cylinder wall.

So it could be caused from a spun bearing, or maybe it just let go form excess thrashing. Who knows what condition you will find the internals of that motor if you pull it apart, you going to pull it apart?

*EDIT*
Funny how you ask if we think it was a spun bearing (while we didn't know what car it was) then toyomatt84 give his opinion that it wouldn't be and you reply "no trust me, i spun a rod bearing."

No, trust me, you can't cause destruction of that magnitude with just a spun rod bearing. There's more problems than just a spun rod, if you KNOW it's spun.

Maybe he means the spun rod bearing caused the major failure? A spun rod bearing that someone stupidly continues to drive and put power down can easly cause the rod to throw.

Best thing is to pull the motor and find out for sure what you did.

Yeah. What happened was I copied this originally off the thread I made on a car club im in that specifies for dsm's, a Spun bearing was the cause of that hole. Its also known as crankwalk in the dsm world.

Well yeah okay it wasn't you so why are you concerned?

I'm just curious as to see the block myself, I knew it had something wrong with it, I was just surprised to find a gouge in my oil pan...nearly missed the transfer case though.
