Nice writeup and pics. Thanks for taking the time to do that.

Now if we can just get over this winter bull$#it and start riding...

 

HELP - I am lost - I installed the new High Volume Oil pump kit with enhanced scavenging and it seems my front rocker box breather is being overwhelmed with oil. Idling forever it never happens but is I ride it around the block, the front breather tube inside the aircleaner reminds me of a snot nose kid. A little burble of oil pushing out and being sucked back in, back breather tube is dry and breathing.

1 - Took rocker cover off to inspect my Doehrty Myst Free Breather. Disassembled to confirm no debris in umbrella seal area.
2 - Rode around the block and had oil in the bottom of the air filter
3 - Took rocker cover off and removed rocker assembly to confirm O-Ring in place. O-Ring was in place between rocker arm ASM and bottom rocker box.
4 - Noticed umbrella seal tittie was folded over and had been since I installed these several years ago. Just in case tittie was holding seal up I trimmed the tit.
4 - Blew thru rubber vent hose and capped breather hole in head looking for a leak. No air leak, between lower rocker box and vent tube in throttle body.
5 - Relaced Rocker ASM and top cover, rode around block and again a few drops of oil in air cleaner from front breather tube.
6 - Less than 90 miles on this build. Oil level is mid way on the stick. It just seems the oil is filling the head up faster than it can fall back to the bottom or faster than the oil pump scavenging can get it to the tank.
7 - I folded a blue shop towel and pinched it between bottom of breather cover and bottom of filter. I want to think this will go away with better sealing of the rings but can't get it outside to ride with bad weather.

 

Not sure where to look? Did you do a compression check?

 

What is your idle and running oil pressure?

 

Is your lower rocker cover gasket on upside down, blocking the drain hole?

 

I see that your oil pressure is high, is the relief valve (ball) stuck?

 

Knew back when you posted your oil pressure, it was way too high but I assumed you wanted it that way. All the manuals say on a TC that the idle oil pressure should be below 12 or so so you do not overwhelm the cylinders with the cooling oil jets and maintain pressure thru the engine at idle. Also the one way umbrella seal are out so they restrict inward in like a intake backfire. Back when Harley first stuck the injectors in for cooling, they discovered that at idle, the engine can take more heat then the oil. Your pressure relief should probably be set at 40 max. Interesting when you bump up pressure and the return, guess you need another 3rd system check to work around the jets on a TC.

 

Some had this issue with the early SE plates. All options still on the table till the OP does some work.

 

1 - Oil pressure was way high at first start, almost pegged the gage. After cool down and 2nd start the oil pressure went back to what I remember when it was new, just above 32PSI cold and around 32PSI idling warm. Yes I think the relief valve was stuck the 1st startup. Can't say I have seen hot idling yet as it has been too cold to ride and I want to be sure to seat the rings under compression.
2 - Compression seems fine but have not tested yet, wanted to seat rings 1st. I barely have enough starter to crank over without pushing compression releases and starter drag sounds balanced between cylinders under compression
3 - I thought about the bottom rocker gasket being upside down which is whay I tested air pressure thru. I assumed if it is upside down the air would leak as the breather pocket is not sealed.

 

possible the rings havent seated yet? gasket upside down? Did you drill out the drain hole to 1/8" ?
