After about 3 years of searching, I have finally found how to install the lower dipstick tube in a small block chevy engine.:D The block has a counter bore about " deep. The lower tube goes in first from the top, then the upper tube.http://www.trifivechevys.com/attachment.php?attachmentid=1976&d=1372095782:D The flare or ring on top of the lower tube keeps it from going all the way thru the block.
