well guys i purchased a 1941 chevy 3/4 truck with matching numbers and it was a barn find....well i got it running and had 15lbs of oil pressure while it was running about 2 minuts...then i heard a low nocking so i turned the engine off and took off the valve cover to find the brass oil supply line that runs to rockers broken off at coupler...then i found a bent rod and frozen valve @ intake valve #4 ......it ran pretty good even with the bent rod.....the valve is totally froze....so i dumped oil on it and will wait until tomorrow to try to move it...is there anything else i can do to get if free again and were can i get a manual to rebuild it.....and is there a replacement brace line for that oil line that runs from the rockers down into the block.........any help would be appreciated...there seems to always be a catch in these barn finds.........
