its an 86 oldsmobile cutlass supreme and the compression is zero how would i be able to locate it

Locate what; the compression?

Engine size would also be good to know?

If this is a 3.3Lt V6 the timing chain has likely let go; if it has, there’s a good chance the valves are now bent.

its a 5.0 v8 86 oldsmobile cutlass supreme and there is no compression in any cylinder. the firing order is correct, nothing seems to be out of place. the valves are moving and the pistons are moving and it doesn't appear to jump time. when trying to turn over it just whizzes over and won't fire. example would be if you took the spark plugs out of a regular working motor and tried to turn it over. and all the spark plugs work. i am puzzled and don know what could be wrong
