Hi.
A diesel running backward will be very rough. Yes there will be no oil pressure and would seize very quickly. The timing will be retarded as rightly said will inject after TDC, this is inefficient and increases the heat which may have blown the gasket. The main issue for me would be oil starvation. Running any longer than 20 or 30 seconds would most likely ruin the big end and main bearings.
