Help! 97 breather lines

I've been watching these forums for years. Best friend growing up had a 93 v6 and a 94 4 banger. Best trucks ever. I have a std cab 1997 with 139,000 miles on. Only replace with factory toyota oem parts. Just recently had the clutch replaced. Long story short the shop ripped my breather hose out, then capped it off and couldn't find the leak. I found it then just ran a new hose. I've looked for a solid week trying to find the factory hose with breather that runs up to front fender! Does to connect to the transmission? And could anyone possibly please direct me to the right hose pn????? They also broke the clip holding it to fender . Amy help is very very very much appreciated. 97 standard cab. 2.7 4x4

 

The 1997 Tacoma with 5 speed manual transmission (W59), 4x4, and 2.7L has four breathers:

• Rear differential
• Front differential
• Transmission
• Transfer case

I discuss each in detail below with additional guidance and advice.

The rear differential breather plug (P/N 90930-A3001) simply sits atop the rear differential on the driver side. It frequently clogs due to exposure to the elements. It would behoove you to extend the line for that breather irrespective of whether or not you drive through deep water. In order to do so, I suggest installing P/N 90404-51016 union into the breather plug hole in the rear differential. Cut about 5' of 5/16" fuel line. Insert that fuel line onto the just-mentioned union. Add a Dorman P/N 924-284 breather plug (differential vent) on the opposite end of the line. You will need 3/8" fuel line for that plug, so find an appropriate 5/16"-3/8" brass barb to connect the different sized fuel lines together. Run the fuel line somewhere high. Most people run it along the parking brake line and up to the pipe running into the fuel tank. Use zip-ties to secure the line. As a word of caution, the threading for your rear differential cannot accommodate the couplers included in the ARN differential breather kit. Save yourself some $$$ and use the above-mentioned method instead.

The front differential breather plug is different. It consists of a solid pipe coming out of the front differential which connects to a piece of 3/8" fuel line that terminates with a breather plug (differential vent) visually resembling the above-mentioned Dorman P/N 924-284. The breather plug is in the engine bay on the driver side wheel well. It is just below the EVAP box, and it connects to the wheel well with a C-shaped plastic clip.

The transmission and transfer case breather plugs (90930-03114) are situated on top of the transmission and separated from each other by only a few inches. Go into the cabin of your truck. Remove the shifter balls and housing using a screwdriver until the transmission is exposed. You will see two little metal nubs on top of the transmission which wiggle when touched. Those are your breathers. If you drive through deep water then it might be worth extending those lines. Follow the advice which I provided above concerning the rear differential. You might want to consider using a small filter pod instead of a breather plug for your transmission; this, however, is completely up to you.
