It's not a scare tactic...we've replaced many a 4.3 engine
because the oil cooler lines blew off. Your lines might
hold, they might not....it's up to you.

Don't even bother, this will do nothing.

If you want lines that are guaranteed not to leak, then you wont
want to buy the GM hoses. Even the supposed "new" design
hoses leak. You might want to investigate the possibility of
having some custom lines made...I know that power steering
hoses can be custom built.
