How does a chain tensioner work on a timing chain?
A timing chain is kept under proper tension by a chain tensioner. A chain tensioner could be operated by a spring-loaded mechanism or oil pressure. Timing chain, tensioner and chain guides. See timing chain animation. Chain guides and silencers are used to keep the timing chain from vibrating. All these components wear too.
How do you replace the tensioner on a Porsche?
Use the Porsche timing tool or an 8mm Allen wrench to lock the crank pulley to the block. Lock the crankshaft (and, when required, the camshafts) in position. It is crucial to lock the crankshaft to prevent the timing chain from jumping when the tensioner is removed.

When do you need a timing chain tensioner?
A timing chain tensioner keeps the right amount of tension in the timing chain by using hydraulic pressure or spring tension. Over time, the tensioner can begin to wear and need to be replaced. Signs of a failing timing chain tensioner can include loss of power, vehicle shaking or backfiring, hard starts, or a rough idle.
What happens when the timing chain stretches out?
When the chain stretches out it can affect the ignition and valve timing. This can cause whining, buzzing, whirring, or rattling noises. Worse, your vehicle could jump time, causing it to struggle to start and run.
