This area of the engine compartment looks like a mess to me.
I'm not even sure what I'm looking at...
Looking from under the car there appears to be a hose exiting the oil filter assy. that's probably leaking, and maybe a water hose nearby as well.
Typically, what's going to have to come off to access this area for replacement of these hoses?
Also - some of the bends look pretty tight. Will I need to find molded hoses or will a straight piece be able to bend enough w/o kinking?
Those would be the hoses for the oil cooler and the lower manifold hose.
The easiest way to replace them is to pull the upper and lower intake manifold.
You will problably have to find the molded parts. I went to NAPA to get some of the specific hoses for my engine.
Like Cougar said, 2 two of the hoses go to the oil cooler. There is a thinner longer "U" shaped hose that runs to the lower intake manifold. You might as well do them all, by now they need it. All heater type hoses, on both sides of the engine, front and back, can be made from the cut to fit hoses mentioned in this post;

This does not include the coolant supply and return lines to the turbo, if applicable. Those need to be high temp hose.
The "U: shape hose is the one exception. NAPA used to have a specific molded replacement for that one, But it may not currently be available. If not follow the suggestion made by Ryan in the link above.
The hoses on the driver's side can be done from under the car also. Remove the oil filter for working room. A Dremel with flexible and a cut off wheel is handy for removing the old clamps
If you do it my way, make sure you use about a foot of hose to clear the steering shaft. I think it cost me about $3, I used transmission oil cooler line which is pretty tough hose.

NAPA carries the high-temp hose, also.
Got all 3 hoses on the DS changed -- For the U shaped smaller dia. hose I used two 4-6" pieces with a 90 in the middle. Looked pretty good - cleared the steering shaft by a couple inches.
Wasn't all that tough from underneath using ramps.
My original problem still stands, however -- for some reason I thought one of those hoses was moving oil, and I was hoping to stop/slow an oil leak.
Obviously, the leak is still there.
So - on to my next attempt.
As I was working I saw what appeared to be oil seeping from a small metal tube/threaded fitting.
This is a small tube (1/4-3/8" OD) that exits the engine downward at the rear, underside DS of the engine, just above and toward the rear from the water hoses I changed. It quickly makes a 180 deg. turn upward and disappears (i believe) between the firewall and head.
Anyone following my desc.? Know what it is? If it's prone to leaking?

These are on the PS I hope.
This sounds like the oil feed for the turbo, it exits block on driver's side then goes around back of engine and up to feed the turbo. Flair fitting so it should tighten up without too much trouble. Oil pressure sender is also in the same area check the fitting intop the block and the sending into the fitting. This is the same fitting the tubo feed comes from.

Mike is right, sounds like the supply line to the turbo. The fitting might be loose or these lines are known to crack with time. Not sure there is a good eway to tell which. Try slightly tightening it. I recommend you use a line wrench as it is easy to strip the fitting.
