Changed head and noticed after startup that there is very little oil at rocker arms, just enough to fill weep hole on each rocker, am used to seeing a good drip on other engines. Oil press 55# @ idl5. Removed #1 rockers and blew into oil press sender hole and air came out at head bolt hole as it should. Plug head bolt hole and blow air and some comes out under timing cover, assume lube? Unit had blown head gskt between #1&2 plus a cracked head. Any thoughts? john
