The engine makes use of VTEC technological know-how for both equally the ingestion and exhaust camshafts, which makes it possible for the engine to modify concerning two distinctive cam lobe profiles depending on the engine velocity and cargo.
The next may be the valve retainers. This issue is due to superior revving And big oil starvation.
