So it wasn't tightened? I thought he said it just failed, how do you check for a defective gasket before it goes bad?
i think the jury is still out on that? he said after a visual the o-ring appeared to have failed, but as AR7 suggested he's only seen it happen when you double up on the o-rings by mistake. I'm willing to guess it backed off and blew the seal. It happens and will happen again. That's why you check your drain plug and oil filter (at least i do) again at the track. I will even check again around lunch time after riding a few sessions. Nobody wants to be that guy. I feel for him, but give him props for manning up.

The oil filter in question was safety wired to prevent it from backing out. It was on tight, even after the oil blew out the seal.

hopefully the OP will post up his findings after better inspection. If that is the case then maybe this is a potential problem with the 06 gsxr 750 that needs to be rectified. I want one of these bikes and am REAL interested in finding out how it happened.

It was nice to meet you 675Trip despite the conditions. I was the one behind you on the R6. Despite the carnage and painful sight of a Ducati 749 missing peices, those last crashes were my sign to call it a day.

There wasn't much happening after the 3pm hour and after a bit of a wait, I got my clothes and headed in to the showers to change. I was in the midst of taking off my boots when I heard the tower call out for C group and I jammed out of the shower back to the bike.

Even if it was on properly, if the old O-ring was still on the engine block it will fail as descibed.

Was the old O-ring on there or not?

In the dark nooks and crannies of an engine, you can unscrew the old filter and not really see the old O-ring stuck on there.

We'll know soon enough whether there was an extra O-ring in there or not. Troggy wasn't feeling too well today, so he went home sick (got too much oil in his system? :teeth). I'm pretty sure it was a K&N filter, though.

Usually double o-ringed oil filters leak immediatly, not saying that this didn't happen, but it would be a rare occurence that it decided to just puke halfway through a trackday, you would think it would of been leaking before hand? Maybe it was and he didn't notice?

before my first trackday with my 675 I went through and checked everything.. I had just taken it to the dealer for 600 mile service and had them switch to water wetter, etc because I was going to the track. they were/are supposed to be track savvy people. I checked the oil filter and it wasn't even hand tight.

I talked to the lead mechanic and he thought it was supposed to be contact plus half a turn, when in fact it is supposed to be 11 lb-ft of torque for the Daytona 675. the K&N I have says 8-12 N-M of torque (I would have to check my wrench to see what that equates to in lb-ft). Needless to say, the torque on the oil filter is extremely important.

To safety wire the oil filter, put a large hose clamp around it, tighten it (don't crush the filter) and safety wire the end of the clamp metal to something. needless to say, line it up so that it is pulling in the correct direction.

It was a K&N filter. The old O-ring was not left on. The K&N filter comes with the ring greased, so that wasn't the problem either.

I have not pulled off the filter yet. I will when I get home from work. Then I'll now more.

Pay attention to all the details. Photograph it before touching anything if you can. See how easy or difficult it is to remove. If it was loose, see how many turns it takes to tighten it up. Inspect the casing. Look at the O-ring itself. There's a reason hiding in there somewhere. You may have cause for seeking reimbursment from K&N if there is some sort of defect in the filter itself.

I've used K&N filters for years with never a sign of any trouble whatsoever.

What K&N filter part number did you use? How tightly was it installed?

If this thing was pissing oil, you were losing oil pressure. Did the light come on? Did the motor make any noises?

Plus one... many of us want to know if there is an issue here. Last time I remember a filter issue it was with some Frams on F2s in the early nineties.

K+N's also have holes in the nut on the end for safety wire, so you don't have to use the hose clamp. I have never seen an oring "blow out"? How do you know there weren't 2 gaskets if you haven't even looked at it yet? Also K+N's are very beefy filters, I suppose if you had some kind of really weird high pressure spike, the O ring would blow before the filter would. I've seen filters blow from extreme pressures but K+N's are extremely beefy, so I wonder if it was possible that a spike in crankcase or oil pressure blew the O ring if it was the weak link. but thats a huge fat guess and very unlikely.

After pulling off the filter I found the problem. It had nothing to do with the filter. It was user error. Despite looking at the engine block to make sure original O ring was not there, it was. Alan is right. it is easy to miss.

Not much else I can say. Rookie move.

I'm glad that has never happened to me, what a mess. It's hard to be mad at someone so willing to admit their mistakes, but if that was me out there and I crashed my bike do to somebody not knowing how to change an oil filter I would be pretty pissed. I would hope I too would have the maturity to let it go and be a good fellow biker. I can't give you kudos just for admitting it, but I will give a huge thumbsup to the fellow riders who are being so acceptive! Glad no one was hurt, and a big knock on wood for anyone else who might ever have a problem like this

Also do you think it was possible it was leaking and you didn't notice before it puked it all out since you have the catch with the track fairings? Did you change the oil before the trackday without testing it before arriving at the track?

Dave, can we move or copy this thread into the crash forum? This is REALLY good stuff, in fact. Alan's on the money.

Sure thing. Perhaps I should have posted there to begin with.
