I dunno that there is a way. There could be an old piece of gasket that's causing a bad seal, a defective gasket, lack of silicone sealant (if that's what was required or used) in that area, cracking or large scrapes in the gasketed surface, etc. To fix it properly, you'll have to disassemble and determine the cause of the leak. Trying to patch it up might work for a while, but in the end you'll probably spend more time and money trying to chase the issue than you would if you just fixed it once and got it over with. Could try to loosen the bolts and squeeze some RTV in, but if you used RTV around the entire cover already, you may create more problems than you solve by breaking the seal the rest of the way around. Also note that if you do this, it probably won't withstand much pressure as there is a very small amount that will actually get under the front cover.
