Oil light on, oil level good, small leak at rocker cover...
Hello everyone,
I just rolled over 2100 mls on my '17 FLHXSE and for the last 300 mls on a trip the oil light came on. As soon as it did I checked the oil level, it was good. I noticed a small leak at the rear cylinders rocker cover, just enough to drip down onto the engine.
The oil light only comes on when idling.
I dropped it off at the shop and they looked at it, saying it might just be the leak, but need further testing.
HD told them to replace the sensor first, and it is still doing it.
Next HD told them to use bore scope to check for scarring in both cylinders. They told me if the see any, they would have to replace the engine.
The tech was aware of the oil pump spacer (or what is called with he shavings and so on) and also mentioned that they 'may' have used the wrong oil pumps on some models. Water assist vs. oil assist, but I have never heard or read about that.
I just heard that they are going to take the engine apart. I assume they did not see any scarring...
They will let me know what they find.
I will update this if I hear anything...
Thank you

Head Bearing
Went for 1000k service on my FLTRX. All seems good except - the head bearing is bad or the front end was put together wrong...
the whole front end is skewed. Wtf?
oh and the fairing or windshield whistles from 15 mph+

or in this case, possibly a bad sensor? Low pressure is also a concern as well in this case. So have it checked as QNman suggests

Since they have looked 3 times, if must be internal with either a problem with excess blowby from piston rings dumping oil into breather box. It could possible be a piece of trash blocking the drain hole back to the sump in the rocker arm box. Excess blow-by or high oil level in the head is going to dump raw oil into the vent system by simple overwelming the 180 turn baffle and filter screen designed to catch liquid oil as blow-by exits the one way out poppet valve and vents the air into the air filter box. That air is drawn into engine. The air flow into the engine does not pull in liquid oil and it drops down. As designed, previous models could hold this oil in air filter box. Make sure you gasket on air filter box looks OK. It only takes few drops to make big mess. You air filter box just could be letting outside air in bypassing filter element if something is not right with it.
The vent baffle in the head with the 180 turn and filter mesh has one way out poppet valves. They are only there to stop reversal air dor that brief overlap in the piston travel, so it's not that.
Before you take it in, open the airfilter box and see if it's full of oil. If it is, it's one of the above.

Had a strange one yesterday and today. Turned on the bike (2500 miles) and the oil light stayed on. Shut it down checked oil, all good. Started again all normal. Today did the same but I decided to not worry about it. After about 5 miles and not turning off I got worried and pulled over and turned bike off and re started it... oil light turned off and all good again. No change in motor sound etc.

Def. get it in. I was having the same thing, intermittent oil light but on restart it would clear. With the excess oil blow by....dealer now thinks its an oil pump issue and I've now seen a couple other posts with same issue. So at least three bikes at my dealer with metal shavings in the oil....This could be a major recall???

Metal Shaving in Oil
This has been an ongoing issue from almost day one of these bikes hitting showroom floors, some literally never made it out of the dealer parking lot before popping up. Harley seems to be handling the issue, but I am curious as to just how many have had this issue now. Reason I am not a Beta tester and hoping my son's SGs doesn't have any issues.
Hello..just bought a 2017 SGS about 2 weeks ago..so I have some Skin in this Game..I am trying to understand how the Oil Filter is not picking up the metal Shavings in the oil..I keep hearing about a check valve in the Oil Pump Assembly ?
I had them throw in the service manual so I will look through the oil flow diagram and see if that sheds some light.
I have 411 miles on her as of today..have been keeping tabs on threads like these to see what's what with these M8'S.

1. Don't worry about oil pressure/shaving issues! Ride the bike and enjoy it as so many other are.
2. If you can't help yourself but to worry, add a cam. The whole cam chest is disassembled along with the oil pump. If there is any scaring, you'd see it or the tech would see it. Then ride and enjoy your bike.
