Have you ever been in your truck and smelled a horrible oil smell? Well I have and it's quite annoying, gotten many headaches from it. I have been told that it is coming from the oil vent tube that is above the front axle.
Anyway, here is a DIY on extending that tube past the cab so you don't smell it anymore.
Supplies:
10' of 3/4" I.D. (Inside Diameter) Tubing
1/2" - 1 1/4" Hose Clamp
Screwdriver (1 of Each)
WD40
Zip-Ties
First pic is from the engine bay, this is the vent tube...
Also the vent tube, this is where it runs down the side of the motor...
Here is the end of the tube, right above the axle...
First you want to clean all the excess oil from the outside of the vent tube. The tube is 3/4" O.D., slip the hose clamp on your extension tube and spray a little WD40 on the inside of it. Slide the extension tube over the existing vent approx. 3/4 of an inch and tighten the clamp...
Now you need to secure the tube out of the way of everything. There is a tab with a hole in it on the transmission. We will run a zip-tie through it and around the hose. Here is the tab...
Now run a zip-tie through the hole and around the tube. I found this to be the best place to secure it. It keeps it out of the way of the front driveshaft (if you have one)...
Now unroll the rest of the tube and keep securing it with zip-ties all the way back. I used brake lines to secure it too...
Right before you get to the fuel tank, go over the frame and put the tube on the outside of the frame rail...
I secured the end right before the front bed mount to the parking brake cable. If you choose to secure it to the cable, make sure you are attaching it to a spot that has a sheath over the cable, or else when you press the parking brake the cable with cut the zip-tie and the vent will just be hanging there...
Now you no longer have to smell that horrible smell.
Thanks to everyone else who pointed out where the smell was coming from, I know I'm not the first one to do this but hopefully with some pics it will help someone else down the line.
