How do you replace a Porsche timing chain tensioner?

Use a 27mm socket and ratchet to break loose the tensioner. Note that the tensioner has lots of threads; therefore, it will take a lot of turning to remove it. Replace one tensioner at a time. Prime the new tensioner. Soak the new tensioner in engine oil; while it is soaked in oil, pump it a few times to prime it.

What causes the timing chain to wear faster?

Lack of oil changes, low oil level or poor oil quality can cause the timing chain to wear faster. 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. Chain guides and silencers are used to keep the timing chain from vibrating.

How often should I change my timing chain?

The most common cause of timing chain tensioner/chain failure is low engine oil. If you follow the MINI/BMW maintenance intervals an oil change is only recommended once a year or every 15,000 miles.

Where is the timing chain located on a Mini Cooper?

Unlike most cars, the Mini Cooper uses a metal timing chain rather than a belt made of composite materials. One of the features of the BMW Prince engine is that the timing chain and tensioner are located inside the engine; the major drawback of this design is that when the timing chain or tensioner fails it can cause catastrophic engine damage.

Why to change timing chain?

Improved fuel economy – Changing the timing chain is also going to improve the gas mileage in your car. A new timing chain will ensure that the crankshaft and the camshaft are working perfectly in unison. This ensures that the valves on the engine are able to deliver great combustion. In the end, you will save a lot on fuel costs.

When is it time to change timing chain?

A timing chain is a major component used to keep an engine’s timing in sync, and replacing it is often an essential part of automobile maintenance. Timing chains typically last longer than timing belts and are preferred by some automakers for their durability. Most experts recommend replacing a timing chain every 100,000 miles or so.

When do you need to change the timing chain?

The timing chain normally needs to be replaced between 40,000 and 100,000 miles unless there is a problem. Issues with the chain are pretty common in high mileage vehicles, so if you are driving an older vehicle, or one with a lot of miles, it is best to be on the lookout for symptoms of the timing chain going bad or failing.

How many hours does it take to change timing chains?

Why does my Porsche make noise when I start the engine?

One of the most common issues that cause Porsche engine noise for about 5 to 10 seconds on startup is a weak timing chain tensioner that is not maintaining hydraulic pressure when the engine is turned off and parked for an extended time. Engine won’t stay running. Record the timing marks before you start work.

How many tensioners does a Porsche have?

After you replace each tensioner, crank the engine by hand two full revolutions before you start it. Porsches typically have three tensioners.
