We got our new to us 96 w900 home over the weekend and we have a few questions. first off we pulled the drains on the air tanks and a bunch of water and looks like engine oil came out (probably about a half a gallon total) im assuming this means we need a new air dryer? That seems like a lot to me. Also should there be that much oil in it too? does that mean the air compressor is going bad too?

Also we dont seem to have the low side of the splitter, Im goin to go drive it here quick and see what i can find. any ideas? its a 13spd if that helps.
