It started out with oil pouring out of the main seal. 73 bug, dual port 1600. No big deal. I have parts on hand. Pulled off flywheel, installed new seal. Scraped off old paper gasket thing, put new one on. Put fly wheel back on. (never checked for end play) Put motor back in. Started it up, was going for a spin around the block when it started to stall out. Giving it more gas didn't help much so I shut it off. While trying to figure out my next move, I noticed there is zero end play. Great job. Pulled the engine today to fix the mess. With the engine out I get the correct end play (maybe a little tight but it's in limits). What's up with that? What should I look for next?
Thanks for any help you can give me

Re: End play problem
First, a '73 shouldn't have any gasket 'tween flywheel & crank - the oil sealing is accomplished by an O-ring on all mid`66-up engines.
It's not a problem to use one, however, provided that the endplay is set to compensate for its presence (the paper gasket adds ~.008").
The early non-O-ring cranks used endplay shims with a larger I.D. than those for an O-ring crank; I suspect that anyone who'd use a paper gasket on an O-ring crank may be unaware of that fact and might have used some early shims too - these tend to sling about on the nose of the crank and slice a groove into it where the shims can be trapped, fouling up the crankshaft endplay...I suspect this could be the issue here.
Once the crank is "sliced" like this there's no proper fix short of replacing it

Re: End play problem
I think that the paper gasket isn't an issue on this one since there is the correct end play with the engine out of the car. I might pull off the flywheel again to check for grooves on the crank. Anything else that would affect end play when installed in the car???

Re: End play problem
If the clutch is adjusted too tight, or the cross-shaft is binding, there could be no endplay when installed...

it happens also that if the cut is so far, that goes thruough the flywheel pins, and oil escapes from there to the outside also if all the sealing is perfect.
some years ago i welded such a crank (cut was slight) and worked well.
