So my first question is in regards to this hose. This hose was leaking out of no where yesterday, probably leaked about 1/4 cup onto the ground, and it's definitely gear oil, not ATF. I parked it in the same position that I usually do, so im confused as to why it would have leaked. I'm pretty sure this hose should connect to something...
It looks like a differential overfill to me, but I have never seen or heard of that before

second pic provides a better over all picture of where the hose starts


Then I came across this hose that comes down, I don't know where it starts, it doesn't pull out, I don't know the purpose or function of this hose.


any thoughts? I am baffled by the second hose, haven't had time to try to trace it back, engine was hot when I found it.


My transmission also has a whine to it, I checked the fluid it was low, added fluid (too much, drained it out to the proper amount). Still is whinning, I really don't want to be replacing this transmission so soon, I bought the truck like 1 month ago.
truck is a 98.5, bone stock with about 122k miles on it, auto tranny. transmission was replaced with a rebuilt one about 3-4 months before I purchased it.

 

The first is a vent hose for front axle. Look at the rear axle find the same thing

 

Second tube is the blow by tube for the motor

 

Just seen you said it was a 98.5. Looks more like a 98. Does it have the 12v or 24v?

 

It's a 24v, what makes it look more like a 98 than the 98.5? It says 24v on the side of the truck

 

That vent tube for blow by

 

I thought the 24 valve had the blow by tube on the front of the motor, not by the starter. Does it have a one piece valve cover or individual valve covers with a plastic cover on top of them ? Somebody may have changed the doors

 

can be your filter housing drain tube mine has one that goes down past the motor..

 

Ya but the drain isn't that big.

 

My buds '99 has the blow by tube on the side of block right in front of the starter.
