Switching to synthetic oil after +/- 100k miles on non-synth oil, often but not always will lead to new leaks at the rear(front of car rear of engine) main seal located behind flywheel(oil will drip from flywheel inspection hole), the front crank seal located behind crank pulley/harmonic balancer(drip near firewall), and/or the oil pump seals(drip near firewall). Perhaps oil filter bracket and distributor shaft. These are all under pressure. Existing leaks at valve cover gasket(not under pressure) can get a bit worse, but I do not think a leak will start here when you switch.
I ended up replacing the front and rear crank seals and the oil pump seals, because once the leak started with synth, the leak persisted even after I went back to non-synth. With new seals, I have been leak free for 145k miles with synth.
Theories on synth molecule size and ability to dissolve deposits have all been proposed and disputed, so who knows? Often you get leaks and sometimes you don't.
