It doesn't need to be external breather to work but a catch can is engine basics. At least they don't have to suffer exhaust gas recirculation which is really messy.
The real question is..Where did the oil come from? It’s a paper filter, so it didn’t come from there. Oil doesn’t come out of the intake, so not from there. Oh yea, It must have come from the motors breather tubes that go in to the intake to the cylinders. Imagine all the oil that must have been sucked in to the intake of that motor and into the cylinders. Even with all that suction there was so much oil coming out of those breathers that there is still a good bit of oil that couldn’t be sucked in and ended up in the bottom of the air cleaner. I can only imagine how much carbon has already built up on the pistons and valves. I feel sorry for the owner of that bike. It will probably take its last breaths shortly after the warranty expires, as if almost by design. Wow, wait a minute, those engineers at the factory are a lot smarter than we give them credit for.
That stock air filter box is one hell of contraption 😅. I just avoid that mess all together Thanks Doc Harley for the obscene visual of what HD is putting you through to help fix our bikes
Don't have that issue after doing the crankcase pressure to air intake bypass. I am a bit anal retentive and make sure that I clean everything to new condition whenever I am doing any work. My bike is a 2010 with 30k+ and looks like new, even the mechanicals.
@@Badgerbiker Don't know, but I'm putting one on my 04 Ultra, had to install a breather on the crack case to oil filter spout to stop the dip stick from blowing out.
Great tip as always Doc, I just rechecked mine, dry as a bone on the outside, then took a flashlight and looked through the front screens,,,,all dry, looks like new.
It cost me $7 bucks for a 3/16" tee and 2.5 ft. of heavy duty reinforced hose and 2ea. trimmed plastic christmas tree plug car fastners siliconed in to fill the 2 holes on the back of the filter. And a 1/2" drilled hole in the back bottom air box... On my new 2023 M8, 114 ci. Tri-Glide from mile one!. My engine is not going to eat or digest it's own poop!. And never will get an half oil soaked/ plugged up air filter that can't breath!. But this is something Doc can't tell you on here or at his dealer!!..
I got a little more created with mine. I have a hyper charger that I like but hate a carb and filter coated in oil. Ran 2 lines 1 off of each crankcase vent under my gas tank and fabricated 2 small L brackets. Then bought 2 chrome cased filters that were reusable and mounted them one to each bracket. This allows a few things. The engine vent as it should, does not allow oil all over my engine, and when my engine is shut off it allows any oil in the lines to drain back into the crank case. It also looks nice and very professional.
If Harley would fix the blow back to the filter one won't have to clean as much. Harley use to vent everything overboard no problem with oil blowing. Caused me to do a complete top end redo at 4200 miles Harley paid but if they would of fixed the oil pressure problem.
Wonder if there would be any harm in putting a folded piece of pig mat in the bottom to absorb the oil?? I change my aur filter ever oil change. Take the old one and wash it for the next time. And even after 4000 miles, its pretty grungy down there!!
Well what the heck. Thanks Doc, as a first year tech, this is something that just never occurred to me. Id check the filter but never looked down. Im gonna make sure reinforce this habit into the services I do. What other habits would you recommend to reinforce? That could be simply missed like this, by some of us more (admittedly) less educated/green techs.
Attention to details. Take the time to create a Critical Fastner sheet with tools needed. Make it a habit. As you are torquing look around each area for things that need attention. And keep your area clean. When a customer is brought back to your bay to see the issue, confidence is projected in a clean bay…..Doc
My 2019 Road Glide has not leaked one drop of oil. I run a Fueling vented dipstick to help in the venting of my motor. I also don’t abuse my bike. I keep the rpm’s in the low range and use the motors low end torque to move it along. Helps keep the motor cooler and last longer. Air cooled Harley engines are not designed to run hard and fast. I run mine like I run my diesel semi , low and slow.
Common thing for many motorcycles companies.For Harleys as i understand its not big deal if you see oil in filter box as its coming from breathers, but, for other companies as japanese engines if you see oil in filter box this is very bad for the engine.Sometimes this happened because of viscocity oil engine, too thin.
Well if Harley -Davidson would have only return the oil mist back into the lower engine case with steal tubes. Running oil into throttle body and engine in a bad idea. The engine vacuum shows it can't keep up with the oil all over the air filter. I hate this about Harley-Davidson motorcycles. Also techs need to add blue lock tight to the air cleaner bolt replace the air cleaner bolt. I had friends that got their Harleys serviced by Harley techs and the air cleaner bolt unscrewed and air air filter and cleaner crushed on the road. I would like to see a 1328 Revolution Max in the Softail frame and touring frame as well.
Love your videos my 2009 ultra classic yesterday throttle stopped working wont go above 2k rpm code P1511 and P2135 i have been looking on the net but i would like your opinion.
I’ve got a 89 fltc and just been on a run and had oil spray over throttle side of bike from rear cylinder to pannier and oil cover oil been same since last oil change not sure what going on it could be from rear cylinder head gasket but any ideas please

External Breathers for the win
yes sir got mine at DK customs, don't need that crap inside the motor. screw the EPA.
External breather system with a catch can will fix that right up.
It doesn't need to be external breather to work but a catch can is engine basics. At least they don't have to suffer exhaust gas recirculation which is really messy.
External breather is the solve
I went one step further on the oil bucket. I put a drain pan over the top of the funnels to keep dirt & dust from collecting.
The real question is..Where did the oil come from?
It’s a paper filter, so it didn’t come from there.
Oil doesn’t come out of the intake, so not from there.
Oh yea, It must have come from the motors breather tubes that go in to the intake to the cylinders.

Love that purposed pulley. I have one, and a bucket, so I'm in! On my bucket list!!!!!!!!
Maybe harley should fix the issue of oil going though the breather bolts and install a catch can system
That is why us smart folks bypass those internal epa garbage things to a setup where you are NOT dumping oil back into your air cleaner.
Great tip! I actually had that happen to me with the oil leaking from my Softail.
Great tip with the funnels.thank you
Thanks Doc for another great tech tip👍🏻
That is such great message, Doc.
Another good tip from Doc, thanks.
Both were good advice,thanks again, Doc.
Did have that problem with my pan, but it did drip oil, just in different places.😂
You sir earned a pass for historic purposes….Doc
Awesome advice for technicians. You rock Doc those details make you the best.
Such great advice and with just a bit of effort to make such a big difference
Always appreciated Doc 👍🏻👍🏻👍🏻
Much appreciated you watching David…Doc

No problem 👍…..Doc
Its the fed not harley.
The moco would install velocity stacks and low restriction exhaust if they could get away with it.
How do you avoid it?
Thanks for the great information Doc, keep up with the great work.
Thank you George….Doc

Air/oil separator with a return line to the sump. Aviation uses them all the time on big air cooled engines. Motorcycles can too.
STC required and not allowed on all aircraft.
@@Old940 true. But STC probably not required for a Harley. Lol.

Andrew what model are you working on and what year Service Manual?….Doc
Love your vids man so cool just got 114 2023 heritage. Peace ✌️
Thanks Jaman for watching….Doc
I like your previous video on this topic better. Rerouting the lines that create the oil problem. Perminate fix
Another reason to do the bypass
Great tip Doc………
Thanks 😅
Or just install an external breather and the oil won’t get on your air filter.

So basically it has lot of blow-by. Got it! Lol

Dude, could you imagine only working an 8 hour day!?
Wonder if there would be any harm in putting a folded piece of pig mat in the bottom to absorb the oil?? I change my aur filter ever oil change. Take the old one and wash it for the next time. And even after 4000 miles, its pretty grungy down there!!
The more permanent solution would be to externally vent your crankcase. :)

Or better install a Moroso air-oil separator/catch can system and you won't have that issue.

i have a 2009 Sportster. People are constantly putting 3 QTs of oil in them. IT CALLS FOR 2.8 QTS.
You might need that bucket next to you as an oil catch can on that bike.
