already

so last weekend went cruzin about 50 miles and while downin a rockstar beverage I noticed the valve cover was seeping fresh repsol all the way around as if the cover was loose goter home cleaned and re torqed(not loose). went out today and after 20 or so miles and there it is again a wet looking valve cover gasket it's never done this before and the only recent change is a oil change about 300 miles ago and I switched to a k and n oil filter it only has just under 10000 miles. has anyone experienced this? I would hate to think I have to replace the gasket already.

Whatever you do, don't assume that torquing down the head bolts will 'fix' the issue - you'll only cause more issues when you snap a head bolt.

You may have to take it off and replace it (the gasket).

I don't think overfilling the oil would do this, but is your oil level ok?

If this did this on my bike, it would indicate oil seepage from the airbox, where oil gets thrown if it's too full, but the 919 airbox is not above the valve cover, so that's not it.

The only other question is are you sure it's oil? Not radiator fluid or fork oil?

Normally there shouldn't be positive pressure inside the crankcase to cause a leak. You may want to verify that the crankcase breather tube isn't clogged up or pinched off somehow. It vents from the valve cover to the airbox.

Unless the pair valves are still installed and either got disconnected at the plug or failed I think.

Wow 90 bucks for gaskets and seals this better be the problem I just cant think of anything else it could be I know its 9 years old but the cover has never been removed, but just curious anyone out there use a k&n oil filter I know its very doubtful but I did just put one on 300 miles ago for the first time.
