They say it's one of the things to check. I replaced mine but it didn't seem to change anything.
I'm still trying to figure mine out. Whenever I get off the trail and back on the paved road I get a steady stream of blue smoke out the tailpipe for a mile or two and then it's clear again. Could the bumps or angles be causing oil to go where it's not supposed to be?
On street driving it doesn't burn very much. I'm a little dismayed that it burns at all--it's only been 40k miles since the rebuild.
