i was reading this web site http://speedprint.com/deves50/oilfilterinstall.php?page=1&itemsperpage=15
and found it interesting, my 235 already has a oil canister with the two oil lines going to the block, that webpage sais that only the 261's should have the 1/2 oil lines, that got me confused, another thing, why is he blocking the passage going to the main caps? would i have to do this?
