O-ring out of last oil change..

Any idea what an O-ring would be doing at the base of a cylinder sleeve?.. What adverse effects might a missing one have when ran? (93 zx6d if it makes a difference). There's a seperate hose from the main oil passage to the cylinder head, so I'm not too worried that the head has lost lubrication at least..

I'm most likely not going to mess with it, unless I'm bored over the summer and decide to tear it down for fun, and to check exhaust valve condition (was a dumbass when I first got the bike,and didn't know what kind of havoc an opened exhaust could cause)

Here's the microfiche

That o-ring typically seals the coolant passage from the crankcase. No o-ring, might get coolant in your oil (might stay sealed with steel flange on aluminum). O-ring slides around the cylinder sleeve and rides under the top flange......which is all slid into the jug assembly, then installed over the pistons, and sandwiched by the cylinder head. Sometimes the bottom of the cylinder sleeve is captured as well (additional sealing point).

I'm confused why you think its missing. Milky oil?

Well I had a relatively long O-ring come out while draining the oil, and that's the only one I could find in any parts explosion that looks close in size.

I haven't ridden it since though, so no chance to look at oil for coolant contamination. I suppose I could borrow a workmate's coolant pressure tester to see if it holds pressure or not. Thanks for the info btw!

Pics? Could be a bead of sealant. Has the motor been recently rebuilt (or valve cover pulled / sealed with black RTV)?

Most of the cylinder sleeve o-ring arrangements I've seen, can't make it to the sump....or if they did, it wouldn't be in recognizable pieces. If you still have your old filter, cut it apart (can opener or dedicated filter cutter / NOT a hacksaw or cutoff wheel). Check for debris there.

I would say, without metal chips or making oil (water / fuel contamination), run it until it goes BRAAAAAP........BANG! Clatter clatter ka-chunk.

I had thought it might be a bead of sealant..but it looked too perfectly cylindrical when I looked at it.. And now that you mention it being at the top lip of the sleeve it'd make sense that it wouldn't likely make it to the pan in one piece. I did do the valve cover gasket ~6 years ago, can't remember that I used any RTV except for where indents for cams are installed (excuse the lack of correct terminology lol)

Sorry, no pics.. I remember it being about the length from wrist to near fingertip, maybe 1-2mm thick. This was last spring actually, haven't gotten to ride since then

I doubt it was the oil filter gasket, it's a spin on filter up front with a square seal..

The bike's a bucket of problems though, seeping oil from front center of head/piston mating area (head gasket failure?), sounds like valve chain slaps, poor response off idle, poor performance >3/4 throttle.. not to mention needing to do brakes, tires, and cush drive. I'm sure a lot of the performance issues are carb related, as I just used needle height settings from a similar altitude/temp/modification chart when I jetted it for the muzzys exhaust. Still need to research/learn how to tune carbs yet.. (more complicated than I first thought haha)

It would be fun to tear apart, but I've got none of the tools to pull/install anything on a shaft, compress rings, work with valves, etc. yet.
