Volkswagen Jetta - Leaking seals / Intake manifold issues

My 2009 Volkswagen Jetta has 87700 miles with 3 Intake Manifold replacements. Volkswagen recently extended the warranty of this model intake manifold to 120K miles because of malfunctions. I recently had to reseal the cylinder head cover and upper and lower timing cover because of oil leaks. I just returned to service because of blown Rear Main Seal. Can intake manifold malfunctions help to wear out and blow seals? I have never had a vehicle with so many seal and oil leaks.

Turbo 4 cyl?

Yes. Turbo 4 cylinder
