there is a metal hose that comes out of underside of turbo that enters the
engine block around the oil filter, what is it? the previous owner looks
like he had sealed it with some sort of putty, while putting new head
gasket on car this got loosened and started leaking oil, does anyone know
what it does and would caulking fix it? thanks

It's the oil drain hose for the turbo, it should have a silicone O-ring to
seal it into the block.

Also, you don't mention what year you have. Our '85 has a straight drain
tube, but later models have a reshaped tube to allow the oil filter to be
removed without swinging the PS pump out of the way. If you have to mess
with the drain tube and yours is a straight variety, this might a good time
to look into replacing the drain tube.

Just a thought.
