Frequently Asked Questions (FAQs)

1. What does a camshaft plug do?

A camshaft plug is a seal that prevents oil from leaking out of the engine. It is inserted into the side of the engine and helps maintain proper lubrication by keeping the oil inside. The camshaft plug is crucial for the smooth operation of the engine's camshaft, which controls the opening and closing of the valves.

2. What happens when a camshaft breaks?

When a camshaft breaks, it can cause various issues in the engine. One common problem is cylinder misfires. The damaged camshaft prevents the valves from opening and closing correctly, disrupting the air-fuel mixture in the combustion chamber. This leads to poor ignition and can result in engine performance issues.
