I took off my air filter today and there was a little puddle of engine oil that came out from behind the filter, maybe 10 drops or so. I just had the 110 recall done on the engine and have maybe 250 miles on the engine and I know the service dept had to have the air cleaner off and cleaned up some when they put it back together so all that oil had to of accumulated in the last 250 miles of riding.

I have the SE air filter assembly part # 29260-08 and the breather for the rockers comes thru the mounting bolts and dumps out near the top of the throttle body so I would think it would get sucked right into the engine.

It just seems like a lot of oil to me, I would think there shouldn't be any oil building up and soaking the bottom of the air filter

Anyone else notice anything similar or have any idea's ??
Could the service tech of screwed something up putting the engine back together that would cause this ?

Check your oil level, if its too high you will get oil in the breather. Also if the oil pump to engine case oring was not installed propely or pinched then the engine could be wet sumping, you would notice a loss of power with this condition.

Drago,
I've seen this before, and in every case with my machines, I've had too much oil in the pan.  "Too much" means when checking the oil on a hot engine with the bike on the jiffy stand, it was more than half way up the reading area on the dipstick.  Try running 1/2 to 3/4 qt low, and check it religiously.  Should cure that problem.

After installing the screw in dipstick did you notice oil pushing out anywhere else?

Nosir.  Just cleaned my air filter last weekend for no other reason than I was bored.  It appeared normal upon removal.  Back plate was clean.  No pooling.  I definitely think it is a "redirect," but I also believe that if oil level is kept on the low side of the acceptable range, blow-by will be kept to a minimum.  Every once in awhile I'll get a dribble, but nothing pouring out.  Best part is, my dipstick never pops out anymore, but back when it did pop out, I never had dribble and blow-by either.  Just a MUCH bigger mess to clean up.......or having to constantly keep an eye on it and stomp it back in place after snatching the throttle.

When they did the recall did the install new rings? If you have oil carry over into the air cleaner it generally means that your rings are not sealed completely. Somthing about pressure in the engine. I had this problem when they changed the cylinder base o-rings the first time and did not hone and install new rings. So, the base o-rings started to leak again and when they did the recall on I made them install new cylinders, pistons and rings. I broke it in per the HD manual, and no more carry-over. Since that time they put a new engine in my bike. I broke it in the same way and again I have no carry over at all. Check to make sure the oil level is right. If you still get the carry-over your rings are not sealed correctly.

DD, what you described is probably the single most common item that Harley riders experience.  Harley never has had a very good  breather system, and it invariably manifests itself as oil carryover into the air cleaner.  Many of us have found, as noted by others in this thread, that just running the oil level a pint or so below full will dramatically improve the carryover.  When the dealer worked on your bike, did they change the oil?  Make certain they didn't over fill; halfway between "add" and "full" on the dipstick (hot) is the recommended level.  Drain a little if necessary and then see what happens over the next 250 miles.

Well I now have the LCD dipstick, what a surprise - the only one they had in stock 

That locks in but I am still concerned about the pressure purging somewhere. Don't want my bike looking like it has a 110 in it ya know 

[grc]

I think it's time for one of you guys to design a vented dipstick cap with a one-way valve to keep the nasties out but let the excess pressure out.  I can help you drill the hole, but the one-way valve is up to you.  Maybe a little rubber flap glued over the hole?

If you increase your oil pressure (new pump, shims, etc.) would this likely increase your chances of oil purging?    spyder

Duane,
"I think" the pressure is going to purge as designed......through the pushrods, to the heads, into the air cleaner.  That's been my experience since installing the Baker spout.  I mean.......a dipstick popping out is NOT normal.  The MOCO redesigned it to screw in on '07 and subsequent, so installing a Baker spout is no different.  The pressure will simply purge through the heads as designed......although there will likely be some blow-by if the oil level is too high.  Pressure is always going to escape via the path of least resistance, so if the push-in dipstick is slick and oily, it would be no wonder that it would pop out when snatching the throttle as opposed to escaping through the tiny holes in the pushrods, to the heads and into the air cleaner.  JMVHO.

When I got the bike back the oil level was actually on the low side, down at the bottom of the cross hatch area and I have been driving it like that, usually I keep the level at about 3/4 with no noticeable drips before. I changed the oil today and only got out about 2 1/2 quarts including the filter and put about 3 1/4 quarts back in to bring it up to the 3/4 mark area. Service manual says 4 quarts with a filter change but I have never gotten that much out or in. I noticed also that the Ultra service manual says 4 quarts and the SE service manual says 4 quarts too but what about the oil cooler on the SE ? That must hold a half quart or so. And has anyone figured out a way to get the dirty oil out of the cooler when doing a oil change ? I was thinking a air blow gun in the passages after the oil filter was removed but I didn't want to take an oil bath 

Why doesn't the oil that gets pushed into the air filter area get sucked into the motor ? Don't the rocker covers have any baffles in them so only the oil fumes get pushed through and not the actual oil itself ? You would think that after making bikes for 100 years this wouldn't be an issue.

I'm not sure if the stealer replaced the rings and honed the cylinders or not but if the assembly they did on my bike is any indication they probally didn't. The mechanic that worked on it was to say the least an idiot. I got the bike back with parts missing, which I ended up getting back and putting on myself, chemically stained lower fairing doors, which they have ordered new ones to replace and a chemically stained gas tank which they have ordered a new replacement. 

I'll try to get a few more miles on it (of course it's supposed to shower all week now) and see what it looks like again after that.

Hopefully my replacement SE air cleaner, thats on a recall will be in by then and I can swap it out.

Don't really think there is much of an issue with oil remaining in the cooler during an oil change, Drago.  We change it and the oil filter often enough, and enough gets drained out, where the little that remains just doesn't matter.  As for the oil mist going into the air filter, some of it does get burned, but not all of it.  If someone can figure a way to get a 100% burn of that oil mist from the breather, I'm betting they'll be able to live richly in Fairfield County.

Well....OK......maybe you're right, but it was doggone sure funny.
