Ok perfect. I didn't think that was possible, so I skipped even thinking about it! Haha
Now, I noticed the aft rubber cushion ring/seal looks a little worn with some little cracks in it. It doesn't leak at all and I haven't had a problem with it, so should I just leave it in place and worry about replacing the aft cushion ring some time in the future?
If you disturb this area, you will want to at least replace the inner rubber cushion ring (the inner ring does the water sealing).
The combination of the two cushion rings provides the rear engine isolation (I.E., rear engine mount).
Pull the lags from the side engine mounts and leave them attached to the engine so that it can go back at the same elevation.
As for removing the six clamping collar bolts (Tap Bolts), be careful...... these are wet area threads, and may be corroded.
While you have the engine out, you can take a small propane torch to each of the six thread insert bosses. The heat will gently expand the material, giving you a better chance of tap bolt removal.
If you do not need to do this now, I'd wait until the season is over with. If one of these tap bolts was to snap off, you'll be sending the flywheel cover in to a shop for EDM.
