As far as I know its all there, yes. even brought it to a shop, and they didnt say anything about it. granted, its like the shittiest shop ever but... I only have it torqued a enough to stop the play, but like I said, there is no preload on the bearings at all. they still spin totally free no matter the torque.

It might be a stupid question, but is the stem loose?
Is there enough of a gap between topcap and steerer that some compression is possible?

Has the top cap topped out on the steerer?

^^^ This
Check if the top cup pressess on the steerer before sufficient preload is applyied on the bearings, add a headset spacer and also check for clearance betweel the top cup and steerer, it should be 4-6 mm when everything sits in place

with and without a spacer on top of the stem its the same. no preload.

im not talking about the cap sorry im talking about the plastic lid that covers the reserviour in my case the part that says Zee on the brake lever

Does your lever look like this?
Shimano Zee brakes

If so, you're not supposed to remove that reservoir cap. You bleed through the bleed port with a Shimano kit. There's no need to remove the cap anymore, Shimano uses a much more controlled bleed method these days.
yea that's what it looks like I'm not trying to bleed them I'm trying to sort out where a leak is coming from and I'm just wondering how tight that T10 screw should be that holds the 2 assemblies together not the bleed port screw the other one.

Tight. It should bottom out. If you're leaking around the seal between the two pieces you may need a new bladder. But Shimano levers are super cheap and all over the 'web. I would probably just get a new one entirely.

Anybody know if poc offers crash replacement discounts on a one year old dented helmet? Google is failing me on this one.

Any reason I get skip in my three smallest cassette cogs?
New chain/chainring/derailleur and the smallest 4 cogs on the cassete are new also. At first it was just the 11t, so I limited it from shifting into that gear, but now it's doing it in the 13t and 15t as well.

Bent derailleur hanger? I checked mine the other day I was having similar issues and when I checked I was out 1/4 inch front to back and 1/2 inch top to bottom

I'm having a problem where my bike won't shift from first to second in the stand (skips second, goes straight to third), but works fine when pedaling it. I was wondering what I'm doing wrong with my derailleur tuning?

How many chainrings do you have?
Does the limit screw stop the derailleur in 1st?
What happens when you shift into 3rd gear?
Is your b screw adjusted so there is minimal clearance on biggest gear?

I have 1 chainring, and the limit screw stops the derailleur in first.

When I shift from 2nd to 3rd, it goes down correctly while pedaling, however it skips over 2nd when in the stand.

I haven't adjusted the b screw yet, I'll adjust it tonight and see how that affects it.
