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. The manual transmission models reportedly do not have the intake manifold power valves.

I heard loud engine knock that lasted a few minutes before disappearing. I removed upper intake plenum to discover 1 missing power valve and two screws. The knock I had heard was power valve screw inside cyl. before it made it's way out the exhaust. I found the loose power valve stuck in an intake runner.
