Flywheel ?'s
When I put together my new engine on the engine stand, I attached the flywheel while it was still out of the car. When I started the engine up, oil dribbled out of the rear main seal. Basically, I failed to tighten the flywheel down enough, and oil was able to seep between the gap between the rear main seal, and the flywheel. So today, I got back under the car and worked to tighten the flywheel down, and I believe I have it as far down as it'll go, but I still see a 1-1.5 MM bit of the machined part of the flywheel that goes into the engine.
I'm pretty sure that I assembled the front assembly correctly, and my end-play is within spec...so what gives? I know I have to put some hustle into the torqueing of the flywheel nut, and maybe I need to put a bit more into it, but I think that I've done a decent job of that. I have the Racing Beat flywheel nut wrench which multiplies torque by several times.
Any thoughts on this? I'd really like to get my car running within this year (god knows it's been long enough! )

Some rear main seals need to be installed a certain way, before you flame me, yes a rear main seal can be put in the wrong way. Most people just pull them out and they dont look to see how they come out of the motor. I've seen this done several times on other cars. You should probably go look at your old rear main seal to see if one of the sides are different, if you installed it wrong its never going to seal no matter how much you tighten the flywheel. You should also use the the torque specs for that nut that holds the flywheel on, thats what they are there for tightening things as tight as they can be is not a very accurate measurement. There are multiple tools that you can use to stop the flywheel from moving.
If you did, by some chance put it in wrong, just keep checking your oil until you can plan to fix the problem.

That gap is about right, but it's almost impossible to tighten the flywheel nut without an impact gun or a torque multiplier tool.

Are you sure the leak isn't coming from the front seal on the transmission? that is a common problem area.... just a suggestion.

I ruined a brand-new clutch disc in the process.

As for the acid-test...I can either opt to remove the flywheel and check the NEW main seal, which I'm 90% certain I installed correctly, and take my chances. Or reinstall the clutch along with a brand-new ACT clutch disc, install the transmission and pray that the damn thing doesn't leak.
If there's a way to get the engine to spin fast enough to check for leaks at the rear seal without reinstalling the transmission, I'd LOVE to hear them.
