WTF?  That's a lot of oil in a running engine when it pumps out like that with a small turn.
You had any sumpers through the shop Bob? That's got to worth a look if one pops up aye?
To be perfectly honest, I have not seen a single one yet, going to tune a 19 today that I just did cams in that didn't have the new backing plate which I installed.  Pulling a cvo 19 apart as well and will have a look at that area. Crazy to see something like that.
If you don't have a sense of humor you probably have no sense at all.

Sorry to say, but technically what the poster is doing is illegal, it's the same thing MOCO got busted for. He may have had second thoughts about opening up that can of worms :idunno:

How is it illegal ??  He is showing an engine case for a bike what is the legal issue there ??  I have and would again tell HD go pound sand . When I posted the new parts books I got a call  , told them to jam it , 


here is the video ,

Just pulled down a bike to install a cam lifters, etc.  I can see where this could easily be a place for problems as it gets thing in that area of the lifter bore.
It appears that the oil passage from the lifter bore to the piston oilers is where the machining may be off or the case may have some serious core shift. Do you have any more pics of where the oil is actually getting through?

so forgive me if I'm wrong, but so jb weld or something to bloke the hole might fix the issue!!!. explains the sumping on high rpm runs and the supposed cavitation on the return side of the pump as if all the oils in the cam side and none the crank chest causes it to suck air. s&s pump might help but would be over whelmed when only getting oil in one return side not both

JB Weld? I wouldn't trust that stuff inside my engine case. I'd be calling HD insisting they replace the POS that they sold me with something that doesn't have massive casting flaws.

Agree!!!  Hopefully the warranty is still intact .

 :agree: but in a few mouths the first of the m8's will be out of warranty, so looking at the cheap fix for thoughs guys that will still have the problem when there warranty runs out. would i use jb weld, probably not. but the thread had stalled and this is one important tread that needs to keep going even if it mean saying something like that to get it going again and to make people think. thank guys

That hole could be welded up, if warranty was over. Would be a better shot than JB.Weld.

How do you propose welding it without clogging the oil gallery?

I have some experience with JB Weld. No warranty? I would consider JB.
I am an adult?? When did that happen, and how do I make it stop?!

The first M8s (2017 models) were out of  warranty last summer, as they were bought in August of 16.  Has anybody else seen this? Is this a one off casting flaw, or a common issue? Anybody else with an M8 apart can confirm there's more than 1 like this?

Just had a 2017 107 FLHX apart for a stg 4. Checked this area while it was apart and it was good. Lifter bores were smooth too. Have seen lifter bores that are full of pockets and pits.  I think it is hit and miss.

I had a co-worker years ago that once worked in a shop that worked on new engines and components from a major auto manufacturer. He said they did all kinds of "fixes" to correct manufacturing flaws mostly resulting from core shifts. He said they did all kinds of goofy stuff to save a block. He also said he wondered what an engine rebuilder got one of these down the road for reconditioning and saw some of these one off parts to work with such things as offset cranks, cams, odd sized lifter bores etc. Unfortunately these kinds of things happen to all manufacturers. Too bad they aren't caught before the customer gets one.

Well I was thinking that also or some kind of epoxy . I had a set of angle plugs the intake ports were some kind of epoxy that came off a g gas car that set the record a long time ago .I bought the heads and several other parts to build my street motor.  . Never gave any problems

True I was a mechanic for GM and I think that they had a bad run of blocks and seems like the fix was to use a stand and and under size main bearings . After all of the warranty work and crap I saw I went to work in the oil field never looked back

Had a tiny hole like this in a cast iron head many years ago from spring seat machining and core shift. I used one of these to fix it. https://www.youtube.com/watch?v=Pq0wfU4ZaKk
If it was my own bike I would use an epoxy and never look back. Customer bike is a whole different deal.

Thatís pretty cool.  Iíd like to see what pressure it would take to make the lock stitch fail.
