Timing Gear Cover

I spent the morning under my '30 coupe cleaning the underside of the engine and scraping years of muck off the transmission. I'm trying to find an oil leak. My greatest suspicion is the timing gear cover. There is a little pool of oil on the front cross member and it looks wet around a couple of the cover bolts. I think the oil is leaking down from there and then spreading across the bottom of the engine. I recently got Les Andrews' number one book and it appears that both cover gaskets can be changed without taking off the crankshaft pulley. Is this true? If so, it looks like a relatively simple replacement. I hope it isn't a seal around the crankshaft.
 
the cover gaskets can be changed without removing the pulley, as well as the crankshaft gaskets, as they are made up of two rope seals. one in the timing cover, the other in the front of the oil pan.
 
Hi fins2nv. I am gearing up for that project myself. I just received that parts today from Snyder's http://www.snydersantiqueauto.com/1466 but won't be able to start for a couple of weeks. Good to know the pulley doesn't need to be removed. You will need two of the packing. For ~$15 you should be good to go.

When I bought my Town Sedan I was told it was a rear Main Seal and was even given a "Rear Main Janitor" http://www.snydersantiqueauto.com/search.php?q=A-6768&x=27&y=10 with the deal... Never seen any oil in the "Janitor" since installing.

Upon further investigation it appeared the oil is coming from two places, the front seal and the transmission.

I repaired the trans shaft leak so next up the front seal. Good Luck.

Thanks for the info Christian and Y-Blockhead. I should do the crank as well then. Good luck on your work Y-Blockhead.
 
One more question fellows. What about the front engine mount bolts? Do they have to come out to take off the timing gear cover? If so, how do I support the front of the engine?
 
Just put a jack under the oil pan, but be sure to protect the pan with a piece of 2x4 or something similar.
