Sounds like it threw a rod cap through the oil pan. You will have to get under it to verify but it will be obvious.


Yes, tennis shoes may be right, or you have had a valve drop and detonated a piston, which could give the same results, this can be verified also by removing plugs individually and checking for damage to electrode or excessive oil on plug, or by using a compression tester if you can crank the engine at all, chances are if piston shattered the rod may lock under a cylinder wall and heavily damage your engine block. Just another possible scenario.
