Le Mans 1000 Breather Surprise!

[MikeW]

I had one of those "oh s##t" moments recently.

The main seal in the Le Mans had been weeping for a few months so I finally bit the bullet one weekend and pulled the engine out.

Imagine my surprise when I pulled the sump off to discover a good layer of mayo in there. The only saving grace was that it was too thick to go through the oil strainer. Took a few years off I can tell you. My hair would have gone white except my kids did that to me years ago 

Now it hadn't that long since the last service so this was a fairly recent event.

Needless to say I flushed out the breather system and it was completely jam packed with thick chunky snot

Don't know if the 1000 has the same head breather hoses as the 850 LM, but they are mayo generators; I removed mine and blanked off the heads and breather box at these hose connections.
My main crankcase breather goes to a catch bottle behind the battery and so far is mayo free. I've also just had the rocker covers off and done an oil change...no mayo.
