Nissan Frontier Internal Engine Damage Caused by Screws From Intake Manifold

(1 report)

Screws inside the intake manifold can become loose causing internal engine damage if they fall out completely. Our technicians report that using a strong thread locker on the power valve butterfly screws can help prevent them from becoming loose.
