Changed my primary fluid yesterday on my Evo motor. The magnet on the end of the drainplug looked like something had taken a bite out of it! Wondering what the hell could do this! Could find any chunks in the fluid so only who knows where all the debris has gone now. Any suggestions on how to flush the area or should I be concerned?

thanks!

 

Is it one of the tapered ones that you maybe screwed in too far and the chain caught it? If you're overly concerned, pull the primary cover and clean it out.
