Oil misting

[bglidin]

I have a 2010 limited with 23k on it . Sunday it started blowing oil out of air cleaner it has pro-pipe,SE filter, and sest. It has 2300 miles on oil change . Is it saturated breather and should Harley cover it under warranty.

Every four stroke motor has some blow by; the rings have gaps. How long has it been since you cleaned the air filter? Restricted intake air flow can contribute to blow by. Check the connection of the backing plate to the head breather ports; could be loose. Check the internal breather hoses.

Consider venting the breathers to the atmosphere and preventing that mixture of oil mist, water vapor and uncombusted fuel from being circulated back into the combustion chamber and contributing to carbon building up on top of the pistons.

Let the bike sit a few days and it has not puked since . I was told I may have saturated the breathers and to let it sit . He also said it would most likely do it again and I should replace them. Will try to hold out till I can do cams .

It might actually be too much engine oil. I have a 08 FXSTC and if I get just a little too much oil in it, it will spit oil out the intake.

I doubt it. The 2010 models have the "new and imroved" stamped breathers which are supposed to do a better job. Vent to the atmosphere and relieve the pressure in the crankcase. Install some crank vents that will maintain a vacuum in the crankcase and the problem should go away. Plus you won't be venting condensation, unburnt fuel and oil mist back into the combustion chambers.

i have a 2010 ultra classic with K&N stage 1 air cleaner kit, V&H dresser duals and slip-ons, fuel pack and a harley oil cooler. end of last season it started blowing oil after i rode home from sturgis. i thought i over serviced the oil for winter but problem didn't go away. i have the ESP in place till 2015 and i took the bike in last week. i was told that umbrella valves were saturated and stuck open. i have 42+++ on the bike and the cost of the repair to me was 50.00, my deductable. it was covered for me.

I believe that the new stamped breathers started later than 2010. Both my 2010 Road King and Wide Glide have the old style cast aluminum breathers.

I'm extremely curious as well.
Always eager to learn something new.
Please explain.

just saying, the price for those parts is around $12 for the pair of breather rebuild kits

i rebuild the breathers every time im in the heads - too cheap and easy not to

You could be right about the year. I know for sure they were in the '11 models but thought I had seen some in some '10 heads as well; maybe a running change toward the end of the '10 model year but could be an '11 model year upgrade.

Please point out what part of the above is "pure rubbish" and, are you sure it is "pure rubbish" as opposed to just plain old "rubbish"? Like other members, always willing to listen and learn.

Hmmmmmmmmmm...................
This ties in to something I'm thinking of doing when I put a 2 into 1 on my FXD- Back when I was heavily involved in circle track racing, I took a lot of time/ care installing an evac system on the cars I built for customers. I found that by carefully placing the evac tubes in the header collectors, I was able to gain up to 2 to 4 inches of extra crankcase vacuum, and get rid of the oil mist by burning it in the headers- So, better ring seal+ getting rid of messy oil mist+ extra power = all good stuff. Wonder how well it would work on the scoot? Anybody done it/ seen it done? If so, did it work?
