Its easy to see how bad o-rings on the twin pipes to the water accumulator on the back of the engine could be diagnosed as a bad valley pan gasket. But while you're in there it only makes sense to do the VP gasket.
I'm really concerned that by not putting some silicone on the o-rings they are leaking. Doing the job again would no doubt be a lot faster since I don't have to examine everything before I remove it and/or spend so much time thinking things through before I put them back together. Been there done that...and that's why mechanics who've done these jobs a dozen times can get it done so quick. Hell, it took me about three 6 hour segments to do the job that the dealer only charges about 8 hours to do.
