Purchased a 33 pickup with according to the previous owner a re-built engine.
Engine was missing some parts when I purchased it and I never heard it run.
Have just done a compression test and found 1 cylinder at zero. The remainder from 100 to 135 lbs
Have removed the heads, intake and base to check for any issues before going further. The zero compression # 4 cylinder appears to have a stuck valve which has been freed up. As you can see in the 1st picture this #4 cylinder valves look like they are both intake valves, not one of each. Would these valves work ?.

Also in Picture #2 the top of valve springs have some sort of clip with a tab on top of the spring. All of the valve clips except this middle one are tight and the tab cannot be turned in either direction. the middle clip and tab is loose and sloppy. Would someone know what these clips do and should they all be tight ?.

Thanks for any information you could share.
