Because of age/mileage, it's probably bad plastic, rubber, seals, or gasket.
Preform a smoke test to pin point the cause, and focus on the EGR, PCV, and air intake systems for leaks.

Use a Black & Mild shorty for 50cents, and a recycled plastic bag for the air filter to block all air incoming into the engine.
