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.

    Lost power 600 mi. from home,we drove it like that and took it to the dealer next day. Power valve butterfly screws backed off,2 on one valve 1 on another they passed through with no damage to the engine
    (very Lucky)cost us $1200 to fix 'cause we were out of warranty. 3 years later I suspect is what has caused our catalytic converter to fail.
