How to Fix Oil Leaking From the Crankcase Breather

on May 08, 2019

 

Stop the flow!!!

A customer writes, "My crankcase is puking oil! HELP!!"

UH OHHH...

In MOST cases, this is an easy fix. TJ walks you through it in this video.

WATCH IT NOW!!!

 

The customer writes, "My crankcase is puking oil. Help! I vented the crankcase breather down the back of the motor like you suggested and now I'm getting excessive oil coming from what I believe is the hose and higher RPMs -- to the point of it coating the swingarm and sidewall of my rear tire. Any ideas on where to start to get this corrected?"

Well, SH*T. That's not good!

Luckily, we have encountered this situation before... and out of the dozen or so times people have dealt with this problem... every single time it's because someone over-filled their oil. Be very careful when you're filling your oil because there are different amounts for different processes. TJ discusses this in detail in the video above.

A few takeaways:

1. Make sure you're putting in the right amount of oil in your bike

2. Check your blow-by; it could be excessive (what's blow-by? watch this: https://youtu.be/V71Jv14_ljk)

3. If that's not the problem it could be a motor issue
