I have a 1995 previa with 175K miles on it. Its had a small oil leak for at least 4 years, but recently dumped all its oil over night. I crawled under and saw a crack in a small hose about midway between the 2 front seats. Any ideas what this hose is and how difficult it is to replace?
Hmm... is it your radiator hose? There is a large range of starter replacements kits you can get. I don't know what exactly you're looking for but two really good sites for parts are www.tautopartsdirect.com and www.overnightautoparts.com It might help.

could it be the oil hose that comes off the oil tank that is under the hood? I have my leaking but not bad. previa has to feed oil to the crank case and it takes out of the reserve tank, if needed, so you might have a leaking hose.
