It is all true: synthetic causes oil leaks. What happens is that the gunk deposited by conventional oil and ill care, covers the seals. The seals eventually dry out because they are no longer getting liquid oil, and when someone switches to synthetic, the gunk gets cleand out and the seals leak.

BUT, the seals will then begin to swell with the oil and the leaks will stop.

The EGR is contaminated by garbage gasoline deposits, and oil pushed oit of seals and sucked into the intake manifold.

The best thing to do is to switch to 10W30 synthetic and RUN the engine. Do not coast around town at 1500 rpm doing 5-10 minute trips. The oil will never get hot to burn off impurities, like water.

If you suspect there is a lot of sludge, take off the oil filler cap and take a look at the cam, then get a can of AutoRx, add it to the oil, and run it for a 1,000 miles. This is a 1 time treatment, not a preventative thing. It will remove sludge everywhere oil fumes go.
