IMS replacement. Well I messed it up again.

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.

You do run the risk of a major oil leak without the O-ring on the center bolt.

Oh man, I can totally see myself in your position! One thing for sure is that if you fix it, you will feel much, much better!

I decided to take it all back apart and of course feel good about it. There are so many ways to screw up an IMS job.

I recently pulled the airbox out of my car to re foam it. After I had the dash in and was nearly finished with re-assembly I realized I had put a damper door in backwards inside the airbox. I had the same thoughts, and made the same decisions you did.

I didn't want to say anything earlier because I've been there and know the feeling.
It can take a moment. ...a few moments, to get ready to face it all again.
Good decision.

I've seen worse like the guy who rebuilt his 993 engine and forgot to install the rod bearings and ran the engine. True story.

Good call putting back right.
I have been there, not with as complicated of a job but that feeling.
Patting your self on the back, big grin on a job well done.
Looking around and then that incredible sinking feeling when you spot that one piece, the first one to be installed, sitting in the corner.
Then there is that calm before the storm

I almost did it all over again. After I installed the o-ring and reassembled everything I spotted the clip that holds the bearing in laying on my hood. I Completely panicked. Then I realized the kit came with a new one and luckily had photos of the install the verify. So glad to have this all behind me. The old bearing by the way looked great, it's been in since 2012, has been around 40,000 miles and seen dozens of track days

that was a painful read.

Agree, it always sucks when you have to redo something. I usually just call it a day and address it the next day. bonus is that it typically goes much quicker the second time.
