venting out pressure
Both oil & coolant leaks will keep venting pressure until you manage to prevent heat accumulation in pistons.
No1 item to deal with is $49Ea. 4x cam sensors to prevent "$10k oil-in-harness" when oil spreads throughout electricals.
PCVentilation conduite can get obstructed by oil residues given sufficient mileage.

COOLING PLASTICS OPTION
The other 3 will be wet if you sneeze twice.
It's like most maintenance: change all found bad parts at once.
You need to keep all your cylinders running as equally as possible.
Check but keep your "VVT Solenoids": they usually stay okay unless engine got beyond extremely hot.
You really best to avoid oil travelling around tge whole engine bay harness.
Heatsoak is the enemy once engine stop... it's not a bad idea to pop hood to help preserve engine plastics... or cancel stock heat accumulation.
