Oil leaking from underneath oil sump, Murray model 42501X92B

Engine on my Murray rider is 15.5 HP Briggs, vertical shaft. The automatic compression release on cam shaft was broken. I removed the engine, cleaned everything up, replaced the cam shaft, installed new gaskets and re-installed the engine. Oil is leaking (considerably) from some where underneath the oil sump. I have not, yet, removed the engine again. The oil is not leaking at the gasket between the sump and block. Could the leak be from around the sump bolts to block. Bolts were torqued according to specifications in my Briggs repair manual BUT I did not use any type of sealant abound the bolts. My Briggs repair manual did not call for use of sealer on any bolt. I also did not replace the oil seal of the sump at the PTO shaft.

Any help will be appreciated.



Thanks, and we are finally getting lots of rain here in Stephenville Texas,
