Not really sure where to start, need help..

EDIT x2: got a compression tester and currently charging battery and gapping my new spark plugs, can I test for compression with the valve cover off? or Do I need to reassemble everything?

You can compression test with the valve cover off. Worst case, a little oil may leak, no biggie...


The picture with the valve cover off looks pretty good. Like stated above, there's much worse...

Do a compression test on each cylinder wet and dry and post the results.
