Is this normal in my oil? As many of you know I'm doing my 110 to 117 upgrade. Bikes in the air tank off ready to pull the heads and I drained the oild to find this. For size sake the big piece is the size of a dime wide and probably the with of threads on a bolt. Thanks

Is it metallic? Definitely doesn't look normal. Can you open the oil filter and see what else is in there?

Was the bike making any unusual noise prior to tear down?  Is there any metal on the magnetic oil drain plug, or is the plug perfectly clean of ANY metal at all?

[Wookie3011]

This was onthe magnetic drain plug. No as far as noise but I had the engine noise delete AKA pro pipe. I'll check the oil filter.

[Wookie3011]

Heres the plugs first is front and 2nd back

 Perfect timing to see what is going on. Once you tear the heads, cylinders off and open up the cam chest you will see what is going on.
  Do you use octane boost in your fuel?

The size of a dime long and the width of a couple of threads (what size bolt - coarse or fine thread?) is an iffy description.  How about a real measurement?

Going by your present description, being ferrous picked up by a magnet I'll guess it's a roller from a cam bearing.  How it got into the pan without taking out the pump is a good question. Was this engine rebuilt after a catastrophic failure before?

I had a 1/2 inch long piece of oil ring break off during assembly and never noticed it. When the remainder of the oil ring scored the cylinder and it started burning oil I tore it down and pulled the oil pump. The pump was functioning fine good oil pressure, no sumping, but it was trashed from the piece of oil ring. I found the oil ring in the oil pan. I was surprised it went through the pump without breaking.

Yes I do use Octane booster. VP Racing, that shard of metal was .015 x .186 long. I got everything apart. Stressing over the Circlips as that's the opportunity to really screw up by dropping them into the lower. I stopped for the nite and decided to watch a few vids onit before doing it. I've seen them before but I wanted it to be fresh in my mind. What size allen is that for the cam Plate? I need to buy a allen socket for my torque wrench. Tomorrow I'll be checking run out, pulling cam bearings and installing new ones.  Put the chest back together then start putting the jugs and heads back on. I have some nasty gaskets on the rocker housing. Any pointers to easily clean them or just a pain all the way around? When I took the throttle Body off I couldnt remove it untill I removed the heads. Is this normal or am I missing something? Thanks for all your help and information guys. I sure do appreciate it and its invaluable to me.

Not as far as I know its never been into. I got with harley and pulled all the records for it. It's a 2016 FLSTFBS. I do use Octane boost VP racing. What made you ask? I have hella carbon build up on the back Cylinder and reddish on the front.

[choseneasy]

The red on the plugs looked like octane boost was used. Or some other additive.

[Boe Cole]

Was it on the drain plug when you removed the plug and saw it then or did the plug fall into the pan and possibly picked up something that could have fallen in the pan?

[kd]

Aha, good point. 

[Wookie3011]

No it didnt drop in thanks. I'm into it and let you know what I find

[Wookie3011]

It's the size of a grain of rice. Its jaggeike a steel splinter.

[les]

It did seem like an inner cam bearing roller, but guess not since you've got the cam chest open.  So, here goes a dumb wild guess.  Someone before installed pistons.  They tried to use a thin punch to pry the piston clip in.  The punch snapped off and fell into the short block.

[Wookie3011]

It's got 004 Runout on the pinion shaft. So that's average. Lifters look together. Though thanks to WFO Larry Got the B slow bleeds going in. I just dont see anything out of the ordinary besides the carbon build up on the back Cyl vs the front which looks like red rust but no Carbon. Any idea why the stark contrast between the 2?

My guess for the difference is possibly the tune being different between the cylinders - or leaky valve stem seals.

To all the Totally Awesome Harley Techs and members of this Forum who gave me Critical advice and guidance thank you. I'm done with the build and it's amazing. I couldnt have done it without you all. Thanks!
