Leaky oil sump and front tappet cover

[Enrique Claure <spanlab@ceibo.entelnet.bo>]

Hi list, another frustrating day today when I detected an oil leak at the 
front of the oil sump and out of the front tappet cover.  I am thinking of 
how to solve this problem.

1. drain the oil and remove the sump.
2. Fit new front cork with silicone sealer and put a fresh cork gasket for 
the sump.
3. Use a silicon sealer for the sump
4. Refit tappet cover gasket with silicon sealer.

Am I doing the right thing? Thanks for any pointers. Enrique
