Has anyone experienced oil out the breather on their 103 motor?

Has anyone else experienced oil out the breather on their 103 motor?

I think you are going to get oil out of the breather no matter what harley you ride.  I am using the Ness Big Sucker and it vents back into the motor and I haven't seen any oil since then.  I am using the filter cover that they provide which looks pretty custom.  It is a round not oval milled cover that fits over the front of the filter not completely around it.  I think it gives much better air flow than a Stage 1 Kit.  I have also noticed that I have almost no back firing anymore. http://shop.arlenness.com/productdetail.asp?SID=16&Category_ID=12&Product_ID=396   Here is another view. http://shop.arlenness.com/store/productdetail.asp+SID+16+Category_ID+12+Product_ID+398

You're going to get oil out the breather when you ride the bike that hard . I would guess at 95 mph you must be north of 4000 rpm! The geroter scavenge side of the oil pump can't get enough oil back to the tank before pressure forces it up and... out! Fixes  include TP Pro-vent rocker boxes... S&S reed valve and Feuling Oil pump. Probably no oil if you keep it around 80. [smiley=beerchug.gif]

PCC,

It is not recommended to use the Feuling Oil Pump and the S&S Reed Valve together.
Use one or the other but not together.

Geezerglide:

You misread my post...I identified the options...no combinations were mentioned.

Hey Geezerglide;

Why nt use them together? The reason I ask is because I DO use them together on my SERG with a 116 S&S top end and I no longer have the oil blow by at high rpms?
[smiley=nixweiss.gif]Your input would be appreciated.

When I built my 95" last winter, SE Heads Ported & Polished by Short Block Charlie, SE 251 Cam, Stage II remap, S&S Rollers Rocker, Feuling Pump and lifters along wuth S&S Reed Valve. At first compression test, front was 160, rear 170, leakdown cold fron 30%, rear 8%. Thought rings had not seated yet.

Posted this question and info on HTT and got in touch with both Feuling and S&S. Here is the info provided by them and various others.

S&S mention that they are unsure if the holes in the brather/reed valve are large enough when a Feuling pump is used.

The Feuling Pump and S&S Breather Valve are known to have compabiltiy isuues. On page 2 of the installation sheet (at the top) is a disclaimerthat states the Reed Valve "Is designed to operate with OEM style pumps and lifters and may not with some after market components"

Bottom line run one or the other, but not both. Wets sumping, loss of power may result from the use of both. Which happened to me.

After removing the S&S Breather Valve and putting back together bike ran great no wet sumping and power loss. Eventually Dynos at 98.6 HP and 104 lb ft.

My 03SERK with 33,000 miles is now having a lot of oil blow by. I have tried the Arlen Ness air filter and this has improved the situation but it still persists on hard rides. The bigest concern is the loss of power when this occours which, I believe is from a build up of crankcase pressure. Harley tech tip #54 states that this can be caused by mis-alignmnet of the oil pump but I am not sure if that will truly fix the problem. I am debating between intstalling the Feuling oil pump or the S&S reed valve but am not sure which one will give the best results.

Take a look at my posts on the 30,000 mile cam chain shoe. The excesive oil was a symptom of damge to the scavenge side of the oil pump from parts of the cam chain shoe. If you are having this problem I would get those shoes checked.

Wow Guys, Please help a poor lass who's husband is so far away.

Mrs. WeCVO,

Your not having much luck with your bike, are you?

In regards to the Air Cleaner coming off of the intake, I hope your mounitng holes are not stripped off of the intake. I have seen some Air Cleaners come off due to the fact that the fastners were not tightened enough. Saying that you can not over tighten or you may pull the threads out of the intake, aslo you should not use Red Loctite or you won't get the Air Cleaner off. I wonder if that may have happened to your bike.

You mention it just come out of the dealers, what did they repair, maybe they did not tighten AC properly.

Did the oil puke out all over the bike because the Air Cleaner and backing plate were not attached?

I would be having a "Chat" with the various personnell at your dealership & HD in regards to all of your problems.


King103,

On my recent 2004 03 SE 103" engine build, 103" Heads redone by SBC and S&S 585 Cams, also had the S&S Reed Valve installed, during my heat cycling period and break in, running the bike hard on and off, have had no puking.

Will post Dyno results when back in Phoenix in late April.

I look like what I assume a guppy looks like out of water, standing in the parking lot of a HD shop that is closed gulping in disbelief.

Mrs. We, above and beyond all the maintenance issues you have (and most of what you described are unfortunately the likely results of poor maintenance) you also have one straight up warranty issue.  If the low fuel light isn't coming on the speedometer needs to be replaced.  There's not a separate bulb in there to change.  So you'll need to talk with some shop somewhere about that so they can get a speedometer on the way with the mileage set if they don't have equipment to do that at their shop.
