I just finished my 2nd IMS job on my car and just after I bolted the transmission up it occurred to me I didn't install the o-ring on he IMS shaft

Kind of one of those points where you just abandon the project altogether in frustration but I have a track day next weekend so it needs to get back on the road. The missing o-ring won't harm the IMS bearing but will cause it to leak if it can sneak past the bearing shaft, and cover, and shaft nut. I'm seriously considering just saying fck it and running the car. What do you guys think is this a clutch compromising leak or a weeping leak I'm looking at. Between clutch replacement, IMS, rms, and input shaft replacement I've had this transmission out more times than I can count.
