Use a LEAK DOWN test to find out where it is leaking from ! Most mechanics should be able to do this
noo you can find out if your rings are stuffed with compression test

first there's the normal compression test where you pull out all spark plugs, disconnect the distributor plug, remove the fuel pump fuse and plug in the compression tester while someone is inside with foot down on accelerator and cranking 6 rotations

and to test even further you have to squirt some oil into the cylinder and crank it a couple of rotations then do the compression test again 1 by 1 then compare the numbers from test 1 with test 2(with oil) if its a big jump in numbers then there you go its your piston rings
