Brizo offers the best advice: find the leak BEFORE you take it apart again. Once you have it on the floor it is impossible to run it etc. Leave it in the car and search for the leak. I have laid on a creeper for a long time occasionally with engine idling away and not even blinking waiting for that first drop of oil to appear.

It sounds like you have a million hours tied up to fix this leak.Do yourself a favor and buy a black light kit and some dye.Put the dye in the oil and drive car for 50-100 miles.The dye will leak out and show you the exact place where it is coming out.

I read for a while before discovering it was an old post and I had weighed in before. Looking at the picture again it seems like the oil on the floor is left of center, although it's hard to tell with the angled view.

I would certainly agree with all the comments above to take the time to determine where the oil is coming from, beginning with a clean and dry floor. A guy needs to see where it's coming from initially which is hard to do after it has accumulated on the floor and moved.

Air flow on the road can make the accumulation move rearward on the powertrain as well.

We haven't heard from the guy who started this for over a year. Perhaps someone could PM him to post a follow up. Who me? I don't think so.

I had a friend who had a leaking crank main seal. In his case he had removed and replaced the seal several times. However, his not being familiar with Corvair's for years like some of us, I finally had a chance to get over to his place and look at the situation.
He had nicely polished the crank-seal area. He used the correct seal.
What I noticed is that he never used a clutch housing - bell housing gasket! The previous owner had installed the main seal from the flywheel side when the engine was last torn down. My friend did not know the difference.
So it all boiled down to the seal being installed backwards.

My question, can you stop a corvair from leaking with all these modern gaskets and sealants on the market and if so how many miles can you get of trouble free leaks????????????????.

Incidentally, and FWIW, my last attempt at repairing the seal leak used a Speedy Sleeve. The sleeve installation went fine, no hitches. It leaked worse.

Until I get it apart again I won't know if I simply messed up the seal (not likely as GREAT care was taken to not nick or otherwise damage it) Grease was used on the seal and sealant was used on the bolts, (including the lower bellhousing bolts)

Really hoping the dye is definitive... IF it's coming from the seal I am torn as to how to proceed. Remove the Speedy Sleeve? The crank looked perfect, the sleeve was used in an attempt to increase the diameter of the crank slightly to try and help the new seal. Use Clark's 'spacer' to slightly move the seal to a new position on the crank?

The seal was NOT Viton....

In any case I will take pictures along the way so you tell me what I am missing.

Right now it's looking like it's going to be early October before I can get to it.
